UPS and Power Distribution Unit Electronics Repair
A UPS that fails to hold load or switch over correctly puts everything behind it at risk. Sinsal diagnoses and repairs the electronics inside UPS units and power distribution units at the component level.
Equipment Covered
- UPS inverter and charging boards
- Battery-management circuitry
- Power distribution unit (PDU) electronics
- Transfer-switch control boards
Common Faults
- Unit fails to switch to battery power during an outage
- Battery no longer holds a usable charge despite testing as healthy standalone
- Output waveform distortion or voltage regulation faults
- Alarm or fault indicators with no clear external cause
Diagnostic Process
- Load-bank testing to confirm actual runtime and switchover behavior
- Charging-circuit and battery-management board testing
- Output waveform and voltage-regulation measurement
- Component-level fault isolation before repair is quoted

Frequently Asked Questions
Common Questions
Can a UPS that fails to switch over be repaired?
Often, yes — this is frequently a transfer-switch or charging-circuit fault rather than a failed battery. Assessment isolates the actual cause before repair is quoted.
