Original new and factory-sealed SDCS-PIN-41A 3BSE004939R1 in stock!!!
This is an indication, that a strong overcurrent has happened due to
one of the following reasons:
- An internal short circuit between the phases (line side) because
of a defect thyristor (short circuit inside a thyristor from anode to
cathode).
- An internal short circuit between the phases (line side) because
of circulating current ina 4-Q converter (malfunction of the control electronics, no thyristor defect).
- An external short circuit at the DC terminals of the converter
without sufficient impedance.
- A commutation fault during inverting mode operation (active
braking with high current, high EMF and with low AC voltage).
