KPS Intermediate Circuit Overvoltage During Charging

Hva betyr Overvoltage PMx during charging ?

An overvoltage condition has been detected in the intermediate circuit of the KPS module (PMx) during its charging phase. This is typically caused by a mains voltage that is too high.

• Intermediate circuit voltage exceeds the safe limit during the charging process.
• Power supply surge during system startup.
• Faulty pre-charge resistor or circuit.
• Incorrect charging sequence or timing.
• External voltage transients.

1. 1

   Measure the incoming mains voltage at the KPS input terminals. If it exceeds specifications, identify the source of the high voltage.

2. 2

   If the mains voltage is consistently too high, consider installing a transformer to adjust the input voltage to the KPS.
