MODERATOR ACTION: all your 23 posts are only because you want to repair an UPS don't you think you have asked enough??
Anyone can give me some idea on what's possibility Part Fail/ Faulty if the UPS doesn't give any output voltage during it's run on battery?
I wonder why I already replaced 4pcs Power MOSFET and the Voltage regulator IC but the system still fail.
For your information, during the UPS run on battery, it's indicated the UPS failed and doesn't give output voltage. So, when I switched on the UPS again (Switched on the Incoming Supply). The relay doesn't working to cut off the supply from a battery after the supply take over by commericial AC supply.
The Power MOSFET original part number is STP60NF06, but unfortunately I can't get it, so I replaced it using STP60N06. Same to Voltage Regulator IC, I replaced LM317 instead of original part number is LM317T. Is it will affected the system?
Hope someone can give me an idea how to solve my problem.
Thanks!
