Zebronics UPS not working.
My UPS,Zebronics ZEB-U725 UPS is not working when there is no main supply. If I switch it on when there is no main supply, momentarily voltage comes on its out put socket (Which can be seen by a volt meter only) then shuts down, even when load is not connected. I checked the battery voltage. It is about 11V. When I switch on the UPS the battery voltage comes slightly down ie it comes down to about 10.5V, then returns to 11V as the UPS shuts down. Please suggest solutions.
Hi @ pvr59ksl
How long the UPS is in service?
Is the UPS still under warranty?
If so, send in for repairs.
else you need to check and inspect the internal main board .
