homage ups control card circuit diagram
homage ups control card is the best protection card for microcontrollers used often in old models now brands avoid the control card and place the microcontroller in the main PCB of the ups that’s less protective.
homage ups control card benefits:
- the control card is installed vertically at the side of the main PCB to protect the microcontroller from power track interference.
- the control card is easily available in the open market and the main PCB controller is not available after burnet.
- protect microcontroller life and working accuracy.
how to repair the homage ups control card?
The homage ups control card consists of three sections power supply, microcontroller, and dual operational amplifier lm 358 ic that is used to read Wapda input voltages to the ups. the control card is difficult to repair for fresh technicians because some faults of the control card are very critical to trace and in some cases, we have to replace it with a new one. some common critical faults of control cards are low output voltage reading, not shifting at charging,wapda voltage readings problems. i hope this diagram will help you to trace the fault in the control card.
