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. 👍 👍👍
Sir yours videos is very knowledgeable.and great effort from your side. Sir requested you kindly make a video on 1 kva and 2 kva how to check suply in iverter and pfc section of 1 kva.
Sir I am already expert in repairing of inverters that is the resason that I have checked its gate drive, i have also changed it's ic18(H-driver) smd ic, i found there is no input signal at pin no 2 & 7, Also I found voltage is at pin 3 & 4 that goes out from it's pin 13 & 14 also at pin 10 & 15 that drive voltage is absent. I think it's ic21(361-0025v2) is perhaps faulty because there is no any voltage at pin 4 & 7 of this ic which goes to pin no 2 & 7 of ic18(H-driver)
How to check gate drive of this ups, sir in my apc smart 1500 ups gate drive of +ve chennel is missing results no output how to repair this problem please help me.
