hi guys my ups is giving very high voltage about 290v with no load and 260-270v with load, i lost many mobile adapters due to this:sad:. how can i set the voltage to 230v???is there any problem in transformer???
can you explain this? how can relay control the voltage or regulate it????
yes its locally made and i checked it before. but now its damaging appliances like fan, mobile charger, and adopters.Is this a first time that you had checked the output voltage of this UPS? or had checked before? I think you are using a locally made UPS. If YES than don't worry, its normal. The voltage goes lower and so on upon increasing LOAD.
Localy made or not this is wrong situation, and you will continue destroying your devices. UPS must have appropriate voltage on output 220V/110V. Maybe this is bad design or some "expert" made that, or have some failed parts inside.
