The price of a double conversion UPS will be some lost power efficiency. In the conversion from AC to DC and back to AC will cause some of the energy to be lost as heat.
Standby UPS : the utility companie's AC runs the connected AC equipment , Directly . The UPS only needs to run the float battery charger maintainer voltage. ( Very efficient ). When the Standby UPS goes on Battery power , the efficiency drops because now the the connected load is powered from the DC to AC Inverter ( 1 conversion ) The battery must supply this inefficiency loss . A connected 240 watt AC load will be using 240 watts + a small extra amount when running on AC directly . When on battery , a connected 240 watt AC load will be using about 360 watts of battery power . Thus the Standby UPS is inefficient only when running on the Battery ( which rarely happens ) Online UPS , The DC to AC inverter is powering the connected AC equipment Full Time . This is very inefficient to get 0ms switching time . A connected 240 watt AC load might be using 360 to 410 watts of AC , Very inefficient which occurs when running on commercial AC power from the wall outlet . When this UPS goes on battery power , the connected 240 watt AC load will cause battery power to reach about 360 watts ( same as for the Standby UPS when on Battery ) The high current DC power supply will also have it's own internal power loss ( more inefficient ) Double Converision , 2 Conversions back to back: AC to DC then DC to AC sounds cute , but is very inefficient . summary : when on Battery power , the efficiencies are the same for both types of UPS . when running on commercial AC outlet power , the Online UPS is Very inificient . Most Homie's will want to go with a Standby UPS . If you want an increased electric bill , then go with the OnLine UPS . Online UPS is basically OFF Grid , as ALL AC is now coming out of the DC to AC inverter . a Facsimily of the commercial AC wall outlet . I think i want to stay with the Standby UPS . Standby : the battery is maintained at 13.5 volts and the battery is in Standby ( not doing anything ) the UPS DC to AC inverter is in Standby ( not doing anything ) the commercial wall outlet AC is Passed through the UPS to Directly power the connected AC equipment . The Entire UPS is truely in Standby .
Can the output of offline or line-interactive UPSs be a pure sine wave when delivered by the inverter, or always a square wave or modified sine wave? The Online/double-conversion models shall never deliver a crappy AC signal, that is clear
This is great instruction, I also have a home inverter and as it doesn't always turn the pc on bought a line interactive ups, so virtually without any load I guess my UPS will run longer?
Hi, which UPS would handle the power variation from a standard emergency generator (not equiped with an inverter) and therefore adequatly protect electronic devices such as computers, tv, router, etc.? I understand that on-line double-conversion UPS would be the best choice, but could the less expensive line-interactive ups work just fine? thanks.
Can you explain the operation and maintenance of three types and cost of purchase compared of all and finally reliable and long life cost effective design compared to another and target customer per each would be extremely helpful. Thanks
Bro I'm searching for a servo voltage stablizer...... Does the online UPS compete with servo voltage stablizer in controlling or defending the low and high voltages ?
Also, they are contained inside most technical devices anyway, so they's is just a selling point to the uneducated. Unless you plan on using sensitive medial equipment.
Jobi - a line interactive will be fine in your home environment and would be one of the better options for you. As you see from the lights, the power supplies in your equipment will still see voltage fluctuation, but it (line interactive UPS) would really shine over the offline during a brownout or sag situation. As an example, if your community had a brown out and you had 100 volts coming into your house, the line interactive would use the transformer to bring that power back up to a higher voltage and deliver more power to the load during that time. The online double conversion units are obviously the best, but they also carry a cost that may not be in the budget for the common home owner. They are normally used for critical loads in an environment that would need as little downtime as possible and as stated, they isolate the load (in your case, your router / pc) from the grid. Hope this helped.
I have a doubt, by using offline ups can we save power from unwanted charging of ups battery?... so can i save electricity from using this type of UPS?
You would in theory save energy in regular use by using an offline UPS compared to an online as the AC-DC-AC conversion isn't 100% efficient. But the point of using an online UPS is that the equipment on the load side is sensitive to interruptions and that the regular wear of the batteries and extra electricity usage is a cheap insurance compared to repairing expensive equipment due to blackouts and grid failures etc. It all depends on what's downstream.
main difference is that in Line Interactive the buck boost(or Voltage Regulator) will try to keep regulating the input voltage to supply load directly from input but after reaching a certain low voltage level it will shift load completely to battery.while online will not regulate voltage and directly shift load on batteries at once which is not good for battery life.
Depends for each brand... Ideally it should be less than hold-up time of computer PSU. Usually it would be less than 5ms. Today's PSU would generally give a hold-up time of 14 ms. I.e. In the event of power cut, the PSU would be able to supply for at least 14 milli sec. Before this exhaust, The UPS should take over the supply.
This was a brilliant explanation. I can't tell you how many hours I have spent researching UPS and trying to make sense of them. Thank you so much.
Yea. Just spent hour myself. Dudes 4 min explanation made for dummies like me
The best video about UPS I have ever seen.
God bless who created that video. Finally, simple and to the point.
This demo has been very helpful. Great showcase of electricity output and how the UPS actually activates
See our very own Tom Calo explaining the different UPS topologies and the varying degrees of power protection they provide.
have you seen our video describing the different UPS topologies? Learn more by watching this fun and educational video today!
*Thank you for the Explanation. That's the video i searched for. Perfectly explained and visualized!* 👍
The price of a double conversion UPS will be some lost power efficiency. In the conversion from AC to DC and back to AC will cause some of the energy to be lost as heat.
And noise too. Online UPSes are most noisy due to fans and also the constantly active power inverter (buzz, coil whine, etc noises are common).
Great explanation video. I must admit I was a bit triggered by the beep beep beep of the offline UPS.
exactly the video i needed. thanx a lot
Great to hear +Md Rishad !
this is what im looking for
100% agree. Very well explained and visualized
Very clear and concise, thank you! Exactly what I wanted to know.
Very Simple and easy to understand. Thanks alot
+Sailaja Rachamreddy Excellent!
That's a very pedagogic demonstration!
+Andreas Lindhé We hope you found the video helpful~
This is great i have learned more from this than from my lecturer all year!!!
Complete Explanation Very Good suggestion
What about interference like EMI or even harmonic distortions ?
Thank you, great explanation !
very nice demonstration
Thank you!
The perfect explanation.. Thank you. All I wanted to know is here.
very nicely explained.
Standby UPS :
the utility companie's AC runs the connected AC equipment , Directly .
The UPS only needs to run the float battery charger maintainer voltage. ( Very efficient ).
When the Standby UPS goes on Battery power , the efficiency drops because now the
the connected load is powered from the DC to AC Inverter ( 1 conversion )
The battery must supply this inefficiency loss .
A connected 240 watt AC load will be using 240 watts + a small extra amount when running on AC directly .
When on battery , a connected 240 watt AC load will be using about 360 watts of battery power .
Thus the Standby UPS is inefficient only when running on the Battery ( which rarely happens )
Online UPS ,
The DC to AC inverter is powering the connected AC equipment Full Time .
This is very inefficient to get 0ms switching time .
A connected 240 watt AC load might be using 360 to 410 watts of AC , Very inefficient
which occurs when running on commercial AC power from the wall outlet .
When this UPS goes on battery power , the connected 240 watt AC load will cause
battery power to reach about 360 watts ( same as for the Standby UPS when on Battery )
The high current DC power supply will also have it's own internal power loss ( more inefficient )
Double Converision , 2 Conversions back to back: AC to DC then DC to AC sounds cute , but is very inefficient .

The only good video I could've find. Thanks a lot 👌
The best explanation. Thank you.
You're welcome +LifeRider 96
Amazing video and comparisons between UPS types

Awesome. Clear and easy explanation!
Hello:
Can you explain a scheme in another video when you do a bypass in the UPS On-Line?
Very Good. Muy buena la explicación. ;)
+Metaconta thanks and yes we will create a new video to explain bypass on a UPS. Thanks!
+Titan Power Inc Hello:
I'm glad to make a new video. I'll be waiting.
Thanks for everything.
This is great instruction, I also have a home inverter and as it doesn't always turn the pc on bought a line interactive ups, so virtually without any load I guess my UPS will run longer?
very good and helpful .... thx
What about the On-Line difference? You show the "Double Conversion On-Line", but what about the "Delta Conversion On-Line"?
But you never showed the online ups as you were lowering the utility voltage??
Thank you very much.........it was really helpfull
+Riad Ahmed that's great
thanks for sharing great knowledge with practically
+pramod raut
You are welcome!

Is there a way to increase the battery operating time of my online UPS?
what's about the sine wave shape (pure or no sine wave)
THANK YOU!!!
Woderful explaning keep it up
Thanks! +عبدالله الربيعي
I have a problem in my building, everytime when elevator starts my light bulbs dim for a second. Would cheap line interactive ups help my pc?
What? How is that even possible in a construction made by the rules? (if it is...)
awesome it's really helpful....

How much time taken for changeover in offline UPS
Depends for each brand...
Ideally it should be less than hold-up time of computer PSU.
Usually it would be less than 5ms.
Today's PSU would generally give a hold-up time of 14 ms. I.e. In the event of power cut, the PSU would be able to supply for at least 14 milli sec. Before this exhaust, The UPS should take over the supply.
