I'm currently troubleshoot a UPS (Uninterruptible Power Supply), for you
information, I already replaced 4pcs of Power MOSFET STP60NF06 t
STP60N06. But the UPS is still not working, the problem now is when the A
supply to the UPS, there is an output. Once I swithched off the AC supply
the UPS indicated fail and no AC supply to output socket.
I'm suspected the LM317T faulty but I don't know how to test this 3 legge
IC. Can you please shown me how to test this component?
Can you please give me more clearer explaination how the IC LM317T work
operation.
I hope you can help me out on this.
Thanks & best regards,
