This man is an amazing master in his job. With his help, through online consultation, we repaired two 5KV UPS controller board. . Only after describing the problem, he immediately showed us the damaged part... Now both of UPS working like a new. Lots of thanks and recommendations from me. I want everyone who has had problems with UPS devices, to know about him. He has an expert knowledge. That's why I write this comment on all his videos. I spent 4 nights without sleep looking for the problem. 👍 👍👍

¿Alguien sabe cuál es el valor de R878 y Q704 (ya que se me dañaron por explosión de capacitor C770 de 20μF y 250 Vca)? Desde ya muchas gracias, el video es EXELENTE!

[@AKElectroTech]

Yes R878 is attached with capacitor and have a value 0.15 ohm 7watt. The FET is a driver fir relay. You can see other FET used for relays, normally 150V because +24V is used on relay winding

[@AKElectroTech]

It is N channel FET relay driver

[@smartups1]

Again very nice video

Thanks

Sir i am checking surt3kva when start on battery giving battery capacitor soft start fault i have checked battery relay ok,th701 702 ok, checked q728,q701 ok but still have same fault.No short at pfc section also.Give me an idea to check

[@AKElectroTech]

install new batteries, I hope UPS will ok

[@ZeinabSanei-jx1bl]

Hi. If during repair, all the leds on the panel should light up(load led), what is the problem? This condition exists while there is only coverter and the buss voltage is fixed by using battery. Inverter and charger are removed from the board

[@AKElectroTech]

Control board may be faulty

[@franciscoescobar3842]

Sera que sabran el valor de la resistencia R870

[@AKElectroTech]

Resistor R870 value is 1k ohm half watt

[@ZeinabSanei-jx1bl]

The first time, after completing the board, the output in battery and line mode was correct. On the line mode, when we pressed the off key, the converter and charger exploded again.(Apc model is lynx 2kva)

[@AKElectroTech]

Control board may be faulty.

[@AKElectroTech]

Can you share model of PSDR board.

Tegangan batree berapa volt?

[@AKElectroTech]

@@ashari_cb 16 batteries are used and it is 12V x 16 batteries = 192V. Now charging voltage should be 13.5V charger x 16 batteries = 216V

Check Q724 and Q707. Q724 is used to switch off UPS.

I have a problem on an APC surt 5kva, when I connect the batteries, the inverter turns on by itself without action on the on button, when I activate with a delay on the off button the power supply remains on
