I'm quite a fan of your video tutorials. But in this one, one point is not entirely correct: double conversion UPS are not the most efficient version, quite the opposite. They offer the best power quality, since there is no interruption at all and the AC is newly generated, so no variations or harmonics from the grid are getting to the equipment. Even the frequency can be corrected or changed from 50 to 60Hz of needed. But this process of double conversion is not the most efficient, since it has permanently the losses of an AC-DC conversion plus the losses of a DC-AC conversion. A UPS with transfer switch has very little loses, as under normal operation no conversion is occurring. But you get all the power quality problems from the grid to the load. And you can not influence the frequency.
Thank you for your comments. You are correct about the differences in efficiency (~96% for line-interactive, ~90% for double-conversion), but this is rarely the decision point for selecting one over the other. As you indicated, there are specific advantages to the double-conversion design, which are necessary in particular applications. Both UPS designs provide efficient operation; >90% efficiency is very good for any electrical device.
An ups battery will burn for 3 days non stop if it has a minor problem. So extreme caution should be taken when using them. Similarly big computers. The fire cannot be stopped because it is an electric dc shot circuit. At least 50 metres gaps are required for usage. Any DC system is like that. Some of them can burst to a range of 2 miles. Similarly huge TVs. Don't ask me why again and again.
THe animation shows a dirty sine at the source, and a clean sine at the output. Do all of these UPS types provide a clean sinewave by nature or is that another feature that some UPS devices may or may not provide?
Hello, @PspiralifeTutorials. Thank you for your question. Yes, it should be clear on the output side. All good and industrial UPS devices should provide a clean output power source because they protect expensive devices on the output side. Happy learning from RealPars!
Sizing of UPS systems is based on load and required time for supplying backup power. A simple way to do this is to add up the loads (in VA or Watts) of all connected equipment and multiply by 1.2. Then go a UPS manufacturer's website and select a UPS that will output at least the total load that was calculated. Then, decide how many minutes of backup power is required, and select the desired model from the data given by the manufacturer. Most manufacturers can help you do the calculation, and many have "calculators" on their websites.
My co-workers at my job let me have a UPS battery like this to hook up my TV, game console, and Blu-Ray player at home for my own personal enjoyments in case the power goes out. I have a TrippLite Internet Office 550VA Ultra-Compact Standby 120V UPS, and got me wondering how long it lasts when the power goes down.
do standby USPs provide any additional protection from surges, voltage drops and instable supply for the load, in other words, could it be used as a protection means?
Hi Hamza, Thank you for your question. Yes, it can. But UPS power, depending on your load, will be limited until the batteries die. Regular UPS for backup use at home will last about 30 minutes. Many date servers have more significant UPS that can last as much as 2 hours. Those types of systems have a generator to back up the UPS.
@@realpars my question is about the case where the standby UPS is standing by, and the power is coming from the mains and not the battery, does the standby UPS provide any protection in this case?
The battery charger shown in the video is a rectifier (definition of a battery charger). Thank you for pointing that out, as other readers may find this information useful!
Thanks for your comment and topic suggestion! We don't have a video covering that at the moment, but I will happily pass this on to our course developers. Thanks again for sharing and happy learning!
A UPS has one or more rechargeable batteries inside. These batteries typically last 2-4 years, at which time, they need to be replaced. The batteries are modular and can be removed and replaced fairly easily. Most can be recycled.
Would a UPS help protect against power problems like surges or poor wiring in a house? Sometimes my soundbar makes a loud popping noise when someone turns off a light switch in my house, and it also causes the lights to dim in my room. I'm worried about it damaging my computer. I also live in an area where there is constant storms/hurricanes and experience several power outages every year.
Yes, a UPS would help protect against the power problems you are experiencing. A UPS gives good surge protection as well as providing a backup for power outages. Make sure you have a UPS that will give you an adequate amount of protection (based on the wattage of your computer and the length of time the backup needs to provide power in the event of a power loss).
The concepts shown in the video apply to commercial and industrial UPS systems. The main difference is in size and capacity of the batteries and switching systems. Commercial office and home UPS systems are typically 1-phase whereas industrial UPS systems are typically 3-phase devices.
What about the power consumption of those three types of UPS? I have a 1Kav Online UPS and when I check with an energy monitor I feel it consume more electricity than it should be.
Every type of UPS consumes some power, even when not connected to the battery supply. On-line UPS systems, by their design, provide the highest level of protection against power loss but exhibit some power consumption during normal operation. If your "losses" are >10%, then there may be an issue with the incoming power (cycle variations, "dirty" waveform, etc.) that is switching your system to battery in order to maintain a "clean" power feed.
Hi, Thanks for your comment! Our courses are mainly based on LAD, we currently do not have courses on STL. Please, feel free to have a browse through our course library to see what topics we cover at the moment. bit.ly/30AVJaR Feel free to reach back out if you have any further questions. Happy learning!
As we stated in our video, you can have more than one UPS as a backup in your data center, protecting your data servers. The transfer switch is normally used on the AC side with generators and the utility power line coming into your plant. You can have more than one generator in parallel, too, depending on your engineering design and risk factors of power loss.
Pls inform do we need to keep ups switch on from switch board( switch off from powwer button) all the time even when we are not working on computer. Keeping switch on all the time affects internal part as ups get little hot. UPS ( APC BACK 600 IN).
You don't need to, but since UPS devices do draw current even when no loads are connected, you probably would want to. By the same token, UPS's have batteries which should not be allowed to fully discharge and set idle for long periods of time.
Hello, @joshuachu2445. Thank you for your question. Yes, you can, provided your extension cord meets the wattage requirements as your UPS's spec sheet requires. Ensure you stay within the length needed in the UPS manual and your local electrical codes. Happy learning from REALPARS!
While the UPS is on-line, either on main or battery power, the static switch is in ‘Load On UPS’ state, connecting the inverter output of the UPS to the load. However, if a UPS fault should develop, causing either the voltage or frequency at the inverter output to exceed acceptable levels or an overload , the static switch changes over without power interruption to ‘Load on Bypass’. The circuitry is all sold-state, with voltage and current comparators determining the health of the UPS output. The static switch fails over to bypass power if a problem internally to the UPS is detected by these circuits.
@@realpars You've left a LOT out. He asked how it works. Lot's of UPS use different methods. Some fully rated solid state, some a mix of contactors and partially rated SCRS. You've not mentioned the two pairs of SCRS, (usually), or much else.
is the battery charger coming with rectifier in online and offline ups just like the double conversion ups?is there any battery charger in double conversion ups? please clarify it for me
The online and offline UPS with transfer switch uses a separate rectifier and charging circuit to charge the battery. The electronics in a double conversion UPS is a little different, but achieves the same result: charging the battery. In a double-conversion UPS, the DC current from the rectifier is usually reduced to keep the batteries from overheating or overcharging. So yes, a double-conversion UPS has a battery charging circuit, but it is different than the circuit used in a transfer-switch type UPS.
Yes. The UPS would be recharged from of the electricity that is produced by the solar system. UPS's sized to power a modest home or cabin are not too large, but can be expensive. A 1500W UPS can cost up to $3000. If you have a refrigerator, TV or electric water heater or stove in the off-grid dwelling, you may need a much large unit or multiple units if these need to be operated during "dark" hours.
UPS systems will charge when the source of electricity is available. When the electricity source is interrupted, the circuit will automatically switch to provide stored power from the battery.
@@realpars Actually I wanted to know does the UPS need to charge separately by switching off the UPS power button or it is charged automatically while it is connected to power source???
Most laptops have a built in battery that acts as a UPS. A small office-grade UPS is a standby (offline) UPS which kicks in when the main AC power is lost.
The UPS should be plugged in whenever the PC is powered on. If you power off the PC, you can power off the UPS, but you want to make sure the UPS is fully charged again before relying on it to provide backup power for the PC.
Confused on how much wattage of the UPS I should buy, I have a high end gaming rig and here are my specs. CPU: ryzen 5 3600 RAM: T-force delta 2x8 16gb ddr4 3000mhz GPU: RTX 2060 SUPER 8gb PSU: SEASONIC 750W Do I need a UPS with a wattage higher than my PSU? Any advice would be appreciated!
A quick way to determine an adequate size for a UPS is to calculate the Volt-Amps required by each device. Multiple the service voltage by the amp rating (on the device nameplate) to get Volt-Amps. For a 750W device like you, considering a power factor of 0.9, you require about 850 VA. Add up all of the Volt-Amps for all devices to be added to the UPS and multiple that number by 1.2. That is the capacity of the UPS you will need. If the device you described is the only one to be put on the UPS, then a UPS of 1000VA would be satisfactory for about an hour of backup power. Don't forget monitors or other peripherals that will need power!
From an electronics standpoint the AC/DC rectifier is separate from the regulator that manages the battery charging. These two circuits work together, and from a "package" standpoint are indistinguishable. The illustration emphasizes that the AC voltage needs to be rectified prior to charging the battery, and then inverted back to AC in the output circuit.
The number of devices that are backed up by a UPS is not an important factor. The total connected load and the amount of time you desire the UPS to back up the load in case of a power failure is what is important. Of course, depending on the number of devices, you will need to have the means to plug in or connect all of the backed-up devices. In your case, an appropriately sized standby UPS wired directly to a set of distribution panels with either appropriately-placed hardwired or plug-in outlets would be recommended.
@@realpars I'm trying to build a project for where I work . I get constant power fluctuations and outages, worse these types of UPS are not easily available. So I'm having hard time to find it.
Hi, when my PLC program is running, sometimes there is a power failure. And the process ends directly, and the program cannot continue. Do I need to select PLC with back up battery? or maybe use UPS? Do you have solutions for this? Thank You
If the PLC has a battery backup, it should continue running the program if incoming power is lost. Sometimes it is difficult to know when the batteries are near depletion, so I prefer using a UPS to back up all PLCs and the network switches to allow the network to continue to operate during limited power outages. You may also want to consider backing up I/O racks as well, but unless you have a very large Rotary UPS backing up main power to the production areas, you won't be able to keep pumps and other equipment running even if the PLC program continues to run.
Enrique is correct. UPS's and VFD's are very different electrical devices. Usually, UPS systems designed to supply AC to motors and drives are very large (rotary UPS) or alternatively, backup power can be provided for these large loads with generators.

For a 750W device like you, considering a power factor of 0.9, you require about 850 VA. Add up all of the Volt-Amps for all devices to be added to the UPS and multiple that number by 1.2. That is the capacity of the UPS you will need. If the device you described is the only one to be put on the UPS, then a UPS of 1000VA would be satisfactory for about an hour of backup power. Don't forget monitors or other peripherals that will need power!
Try to connect multiple UPS to one another and see hoe many time you would have...
3:48 why separate the battery charger and the rectifier? Battery chargers already have rectifiers in them.
From an electronics standpoint the AC/DC rectifier is separate from the regulator that manages the battery charging. These two circuits work together, and from a "package" standpoint are indistinguishable. The illustration emphasizes that the AC voltage needs to be rectified prior to charging the battery, and then inverted back to AC in the output circuit.
Great video
Thank you, Simon!
Could you make a video of what is an Industrial UPS?
Hi Rob!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
What kind of UPS you buy for more than 200 Pcs and 60 projectors?
The number of devices that are backed up by a UPS is not an important factor. The total connected load and the amount of time you desire the UPS to back up the load in case of a power failure is what is important. Of course, depending on the number of devices, you will need to have the means to plug in or connect all of the backed-up devices. In your case, an appropriately sized standby UPS wired directly to a set of distribution panels with either appropriately-placed hardwired or plug-in outlets would be recommended.
@@realpars I'm trying to build a project for where I work . I get constant power fluctuations and outages, worse these types of UPS are not easily available. So I'm having hard time to find it.
Hi, when my PLC program is running, sometimes there is a power failure. And the process ends directly, and the program cannot continue. Do I need to select PLC with back up battery? or maybe use UPS? Do you have solutions for this? Thank You
If the PLC has a battery backup, it should continue running the program if incoming power is lost. Sometimes it is difficult to know when the batteries are near depletion, so I prefer using a UPS to back up all PLCs and the network switches to allow the network to continue to operate during limited power outages. You may also want to consider backing up I/O racks as well, but unless you have a very large Rotary UPS backing up main power to the production areas, you won't be able to keep pumps and other equipment running even if the PLC program continues to run.
@@realpars Thankyou Real Pars, btw do we also need to use capacitor bank? for the supply
Perfect😁👍👍👍👍thank you a lot
You're very welcome!
i love real pars
Awesome! Thank you
You're very welcome!
Good informative video, thanks
Glad to hear that!
Nice video Sir. Please make video on SPD, Barriers and Isolators. Difference between barrier and isolator
You are very welcome! Thanks for the topic suggestion, I will definitely go ahead and forward this to our creator team. Happy learning!
This video was wow thanks alot
Glad to hear that! Happy learning
Like to know about Probes &Vibration Monitoring systems can you do a video on it
Can we get a variable frequency drive that is also a UPS?
NO, a UPS must keep the frequency fixed to say 50Hz in Europe.
Enrique is correct. UPS's and VFD's are very different electrical devices. Usually, UPS systems designed to supply AC to motors and drives are very large (rotary UPS) or alternatively, backup power can be provided for these large loads with generators.
