Microtek 24×7 725VA
Problem – Battery wires shorting and burn problem in microtek 24×7 725va
Fault – Faulty shorted mosfet + Shorted zener diode + Shorted 83202 ibc IC.
Solution –Checked mosfet found shorted > mosfet changed > checked all other components such as gate resistor, zener diode , gate transistor found zener diode shorted > changed diode > changed 83202 IC. Video
Parts used – IRFB7545PBF Mosfet + Zener dode ? + 83202 ic
