Gamatronic Power+ SA 10kVA
Gamatronic · Model Power+ SA 10kVA
Internal electronic static mechanism for supplying users directly from the electrical grid in the event of a malfunction. This feature enables the UPS to maintain a continuous supply of electricity to users in all scenarios. Battery wiring system does not require an input or output transformer External battery cabinet The unit is controlled using SNMP (optional) or RS232 Dry contacts for operation with PLC 96% electrical efficiency.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
UPS stays in Battery Mode after mains returns
HighSymptoms: AC restored but the UPS keeps running from battery, "AC INPUT FAIL" cleared but no transfer back.
Root cause: External input circuit breaker off, input voltage still out of range, or a rectifier / input-stage fault.
Battery test failed / short backup time
HighSymptoms: "BATTERY LOW" early into an outage, scheduled battery test fails.
Root cause: Aged VRLA battery string, or a test run while the battery was still recharging after an outage; high ambient temperature shortens battery life.
UPS remains in Bypass mode
MediumSymptoms: Main screen shows "Manual Bypass" or the UPS will not leave bypass.
Root cause: Bypass selected manually, an overload, or an inverter fault.
AC OUTPUT FAULT / overload
MediumSymptoms: Alarm LED and audible alarm, output phase voltage out of range.
Root cause: Connected load exceeds the UPS rating, or an inverter fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electricity returned but UPS stays on battery
- Open the Event Log and read the Active Alarm to identify the condition.
- Check the external circuit breaker for the AC line - it may be off.
- Confirm the input voltage is within range on all phases on the AC Input screen.
- Reset the breaker / restore input and watch for the transfer back to line.
- If input is good but it will not transfer, refer for rectifier-stage service.
Symptom: Battery test failed
- If the test ran shortly after an outage, wait ~2 hours after AC returns and run a manual battery test.
- If it still fails, measure the battery string and individual blocks.
- Check the battery cabinet ambient temperature.
- Replace aged or weak blocks (ideally the whole string).
- Re-run the battery test to clear the alarm.
