Great video. I adapted your earlier design but swapped the relay for a couple of P-channel Mosfets (an IRF9530NPbF), one for each supply 12/19V. Much faster switching and they don't draw any current under normal conditions so no risk of burned out relay terminals in the future.
use mosfet not the relay, they draw next to nothing current and drop rezistor wont hot so much, u can get mosfets from old laptop battery, they usualy are 30V and 15A ones
Greetings from the other side of the pond. I'm from Romania but live in FL. I'm glad to see a fellow Romanian building cool useful things. It's what I do all day! (Just no time videos)
I like your channel is growing and you can have sponsors and using a pcb always better than homemade circuit boards. I like your work please keep it up.
Its good to see people make their own design and build stuff. You can make this a whole lot easier if you just have batteries a charger, bms and one buck and one boost converter. Use two diodes into the outputs of the power supplies and adjust voltages just under them. When a.c. drops out the diodes pass voltage and their is zero delay. Can be done cheaper and don't need any pc board or fuses, relay or switches.
I've designed a 12V ups system using a boost converter that was adjusted to a voltage slightly lower than the power supply voltage. The boost converter connected to the battery output was in parallel with the wall power supply. So what happens is that the boost converter capacitors were charged to a voltage higher than the converter was trying to regulate so therefore it remained off when there was power. But immediately the capacitors sagged 0.5V under what the power the supply was giving then the boost converter started to deliver power. It worked instantly and it's a simple design.
Looks very nice and it is usable, i have to have 3x 12v and 2x 19v output do i need to change something or can i just split te 12v and 19v output. It would be nice if you could build one for 220v, but that would probably dangerous?
Hi. For multiple outputs it will need a bigger battery and depending on the needed current, it may need a different design. I will soon make a better UPS with a bigger LiFePO4 battery and more features.
if you want instant switchover, use a diode OR gate with Schottky diodes. If the AC-supplied voltage is higher than the battery voltage at full charge, the battery won't be used at all until AC goes out, but it's fast enough that electronics won't reboot. (we're talking nanoseconds)
Use a mini DC stepdown to power the Relay and you'll get an instant relay switch. I made a similar DC UPS project using a relay for the switchover, using a resistor to drain the power supply consumed power, and not efficient in my opinion. I am not an expert but in my experience using the dc mini step down way better. Cheers 🥂
Actually I have same problem when switch from AC adapter to battery mode. I solved it with small bulb or LED connect to AC(with limiting resistor) and LDR sensor(like optocoupler) to activate relay with small transistor. When AC disappeared, the bulb instantly turn off and LDR shut off transistor base then relay too. It take less delay and better efficiency(less current consumption when no load and no charge the battery) than yours.
Lol I just used a diode with batteries with the router and when the charger is on it'll only supply to the router and when it's off the batteries will take the load and to prevent the charger current to go to the batteries I used that diode pretty simple as I get very frequent and short power cuts
i think if you use intermediate relay it will be better than SRD relay and just need to add capacitor after diodes at relay output source that will overcome relay delay so it will reduce the current consumption from the 20W 220RJ you use
I just stumbled across this video and my thought was that making it a continuous conversion UPS might actually be more efficient than that resistor. This would also completely sidestep the need for faster switching.
Hi. I wanted to test different types of UPS ideas. I will make a continuous conversion UPS in the future, with more features and a bigger LiFePo4 battery.
Sorin , I faced this issue with relays before , the resistor approach is not that suitable , it is better to use a capacitor dropper to convert 220VAC to 12VDC connected to the relay , the moving to backup battery will be even faster if power outage occurred .
7:33 I could not understand what he is going to say.. can anyone help me and explain why the relay will switch faster if the supply voltage to relay is low?
Użyj diody zenera w połączeniu z rezystorem np 1k do wykrywania spadku napięcia. Lub przebuduj go na topologie online, przekaźniki i przełączanie w przypadku zasilania bezpośrednio urządzeń zawsze powodują dodatkowe komplikacje. Tak naprawdę nie będzie dużo większych strat jak będziesz napięcie przetwarzać dwa razy, a zniknie całkowicie problem z przełączaniem.
8 pin Ac relay work perfectly, But I Try different method... I use Microsmps(SO12V1000) (110-260) VAC - 12 VDC /1A Regulated Power Supply Module ( Low power consumption, no heating issue ) Just Powered relay separately with this module... You just have to change relay power input source
Hi , for preventing voltage going back to router charger from ups i added a 1N4007 diode which has apx:0.4 v of loss, which lover the output from 11.7 to 11.3 ,and my modem was restarting (not even powering on ) , help me to fix should i change my diode or any thing else..
Interesting project, but you may be able to do what I did and get away with something much simpler and more efficient. Most consumer network equipment doesn't actually require exactly 12v or 19v input. They usually already have internal SMPS dc-dc converters that take the input voltage down to the 5V, 3.3V, 1.8V, etc... that is actually needed by the internal ICs. I have tested my equipment to work down to about 6-8V and up to 20V+ (depends on the input capacitors and specific DC-DC SMPS IC used). So, all that is really needed for a 'UPS' is a dual diode where one leg is fed from a higher voltage AC-DC adapter (19V laptop adapter in my case), and the other leg is fed directly from a lower voltage battery (2S-4S, or large deep cycle 12V lead-acid in my case). The dual diode will let the higher voltage power source through until it drops below the other power source at which point the backup power source will power the output (with no switchover delay). I run my entire home network core on this exact setup. A 19V laptop adapter and large deep-cycle 12V lead-acid battery through dual diode powers my Motorola SB6121 cable modem, an Asus ChromeBox running pfSense, a TP-Link TL-SG108E 8-port gigabit smart switch, and a 5-port gigabit PoE switch (through a XL6009 boost module set to ~48V). The PoE switch provides power (and network) to my wireless AP (EAP600), and VoIP phone. I have an external 12V lead-acid battery charger/maintainer hooked up to the battery. I can power my entire network core off of the lead-acid battery for about 4 days in a power outage. For even higher efficiency, the dual-diode can be replaced with dual 'ideal' diodes, that have much lower forward voltage drop, or even an IC that is specifically made for this exact purpose (i.e. LTC4412).
Very interesting comment!! I recently came around Dual Diode, discovering them actually, they are very handy!! I discovered them while fixing PC PSU. As you explained, they are also used there to get 2 voltages, from same voltage source. I really hoped your whole idea had a visual tuto, to illustrate the whole idea.
Have you experimented with a digital relay? I don't know if it is faster or uses less voltage, but if it does then it might be worth the added expense.
Why do you always put load resistor? I meant I am trying to understand your purest intention of doing that... Because I thought putting a load before even using it would drain current unnecessarily... Why need to do such a thing
thank you for this big work my friend. i have a question, i want build same ups but for the dvr, he need 12V and 3Amp , do you think its safe with same components ? or do i need special ?
The converter will heat up in time with 3A, so I suggest you add a fan. and you also need a more powerful charger, to power the load and charge the battery in the same time.

hi. it depends on what current your load needs. if it needs maximum 2A you can use my design. if your load needs more than 2A, you need to remake the design with a bigger battery pack. you can use the same step up converter to increase the voltage of the battery to 24V.

Hi. You can send me an email with your project, or we can talk on the Patreon chat. I'm guessing that the relay isn't switching fast enough. try to add a load to the relay supply voltage, for example a light bulb, to test if there is any difference.
O solutie pentru problema timpului de raspuns al releului ar putea fi rezolvata destul de usor daca ai integra sursa in cutie. Vezi putin conceptul 'zero crossing'. Din acel optocuplor (eu am folosit H11AA1) poti comanda releul, desigur, mai pui un condensator de filtrare dar macar ai timp de raspuns foarte bun fara a pune o sarcina in plus pe sursa. E doar o parere :) spor la treaba!
Ceau Sorine, un pic offtopic. Am un UPS industrial-ish (3kVA, 72V - rulează cu 6x12V@200Ah VRLA), și mă gândesc să-l transform într-un sistem fotovoltaic on-grid. După mintea mea, cel mai simplu ar fi să-mi fac o jucărie care să-mi comute _intrarea_ UPS-ului între rețea și ieșirea de la invertorul de solare. Vreo sugestie? Sunt noob, apropo. Numai bine, Mircea.
salut. de obicei panourile fotovoltaice incarca bateria si alimenteaza si invertorul. daca la acesta mai conectezi inca un UPS (cu baterie si invertor incorporate) se va pierde din energie. mai eficient ar fi sa folosesti panourile fotovoltaice sa alimentezi bateria si invertorul UPS-ului (daca rezista sa functioneze perioada indelungata). cand soarele apune, sa folosesti un circuit probabil cu releu sa activeze alimetarea UPS-ului de la retea. iar in cazul in care se intrerupe si curentul din retea, UPS-ul va functiona pe baterie.
You could perhaps use one of those 50W AISIBO Aluminum Resistors that come with a heat built on for the relay load resistor. I am also working on a similar Router UPS for my channel so I can relate to your challenges. All in all, i believe you did a great job with this video. I guess your 0.13 sec switch time is the target to beat....hihihi

@@dinoantonio6100 I had some old 18AWG laying around so used that. Seems fine.
Use an comparator to check if supply is less than x voltage and then turn relay on/off based on that voltage. Gives you very fast reaction time.

Salut imi plac videourile tale si sunt un mare fan a electrictati. De mic m am jucat cu motorase si multe lucruri. Oare unde pot invata electrica sau cum o poti numi:) chiar mi as dori
salut. cel mai bine ar fi sa te inscri la niste cursuri de electronica pentru incepatori. cred ca poti sa gasesti si cursuri online. sau te uiti la youtuberi cum explica si construiesc diverse chestii. dar ai grija, unii fac si greseli (probabil si eu am facut cateva :D )
Very cool!
(I am a Korean who can't speak English. So I use Google Translator.)
I wanted to make a small UPS. So I searched Google and RUclips and watched your video.
The UPS I want to make is 24V. Can I do it even if I watch the video and follow it?
Because, I have no knowledge of electricity. But I want to make it. can you help me?
hi. it depends on what current your load needs. if it needs maximum 2A you can use my design. if your load needs more than 2A, you need to remake the design with a bigger battery pack. you can use the same step up converter to increase the voltage of the battery to 24V.
@@Sorin_DIY Thank you for your kind explanation!
I'll try on.
I admire your video.
Thank you.
Hi mate :) gerber link doesnt work again... can i ask for a reupload? ;) thanks!

Hi great work by the way, I ordered the PCB's and made this one. When are you thinking of making another one without the relay, or one with faster switching? Keep up the good work. Do you have a new Full schematic of this UPS?
Thanks. I will make a better 12V UPS with no relay, but it will take some time. I'm working on other projects now.
@@Sorin_DIY Thank you sir for the reply, I have enjoyed All your video's and can't wait for more, but I am going to have too, LOL, Keep them coming and thanks again for all your hard work.
How many mm of cooling fan is installed
it's a 60mm fan
gerber file url not working please update it

Can u make a diy external battery for a laptop
yes, I will make one.
That's great. An external battery with the same function to it's original where you can charge while using it. 😁
Bro will u help me.i made a 12v ups. But when electricity off my router & ups restarts. Will i personally share with u & will u help me to solution it? Please
Hi. You can send me an email with your project, or we can talk on the Patreon chat. I'm guessing that the relay isn't switching fast enough. try to add a load to the relay supply voltage, for example a light bulb, to test if there is any difference.
O solutie pentru problema timpului de raspuns al releului ar putea fi rezolvata destul de usor daca ai integra sursa in cutie. Vezi putin conceptul 'zero crossing'. Din acel optocuplor (eu am folosit H11AA1) poti comanda releul, desigur, mai pui un condensator de filtrare dar macar ai timp de raspuns foarte bun fara a pune o sarcina in plus pe sursa. E doar o parere :) spor la treaba!
Sir can you make ups for computer or how to repair it
I made jcb with syringe and a rc tractor and more it's fun...
si acum sa vina si V2 :D, keep up the good work.
Gerber file link is not working.

When sorin soldering bms: 0% short circuit, insulate with shrinking tube
When I solder bms: there goes another short circuited one
Bravo Sorin
Why couldn't you use a mosfet or just keep the batteries charged and run the power supply in parallel with the battery power
hi. I wanted to do a video with relays.
I use mosfet but switching is still slow.
What will you connect to a gate pin of mosfet?
Salut sorine ba de cand nai mai postat
Amazing video
cant use bjt or mosfet?
Lol. Love the dog poop joke.
Great work!👍
I like whe he says at 9:24 dummy load😂😂😂
Ceau Sorine,
un pic offtopic.
Am un UPS industrial-ish (3kVA, 72V - rulează cu 6x12V@200Ah VRLA), și mă gândesc să-l transform într-un sistem fotovoltaic on-grid.
După mintea mea, cel mai simplu ar fi să-mi fac o jucărie care să-mi comute _intrarea_ UPS-ului între rețea și ieșirea de la invertorul de solare.
Vreo sugestie? Sunt noob, apropo.
Numai bine,
Mircea.
salut. de obicei panourile fotovoltaice incarca bateria si alimenteaza si invertorul. daca la acesta mai conectezi inca un UPS (cu baterie si invertor incorporate) se va pierde din energie.
mai eficient ar fi sa folosesti panourile fotovoltaice sa alimentezi bateria si invertorul UPS-ului (daca rezista sa functioneze perioada indelungata). cand soarele apune, sa folosesti un circuit probabil cu releu sa activeze alimetarea UPS-ului de la retea. iar in cazul in care se intrerupe si curentul din retea, UPS-ul va functiona pe baterie.
Could you drop a purchase link for your Romanian accent. Its the only thing I am missing. 🤘
You could perhaps use one of those 50W AISIBO Aluminum Resistors that come with a heat built on for the relay load resistor.
I am also working on a similar Router UPS for my channel so I can relate to your challenges.
All in all, i believe you did a great job with this video. I guess your 0.13 sec switch time is the target to beat....hihihi
Bravo ția ieşit foarte bine
Good job 😊👍 Awesome ⚡👍
Can it be used for 24V ?
yes, but it needs some modifications to work with 24V.
În viitor îți vei cumpara o stație de lipit mai buna ? Poate cu vârfuri t 12 ?
probabil ca da. insa trebuie sa investesc in multe componente si scule, iar venitul din RUclips este descul de mic. deci mai dureaza.
@@Sorin_DIY ai putea sa îți cumperi noua stație keysger cu vârfuri t 12 sau ai putea sa îți faci tu o stație analogica cu vârfuri t 12.
