Hi all
The output voltage of my UPS is approx 300 volts. I have also checked the transistors, they are working properly. When the battery is charging , through main supply, the output voltage is upto the normal value that is 220 volts, but as soon as the main supply fails and the UPS starts , the output voltage becomes 300 volts. Every time when the UPS comes on load the FUSE is also blowing.
Can anyone pls tell me what is the PROBLEM.
regards
