Advanced Built-in Protection Systems
– Overvoltage protection (OVP) automatically shuts down output if voltage exceeds preset limit, safeguarding sensitive anodizing baths.
– Overcurrent protection (OCP) with fast-acting IGBT gate drive cutoff prevents damage during load faults or short circuits.
– Overtemperature protection (OTP) with thermal sensors on heatsinks and transformer core, triggering alarm and shutdown if internal temperature exceeds 85°C.
– Phase loss and input under-voltage detection ensures stable operation even with fluctuating mains supply, typical in industrial environments.
– Soft-start ramp-up prevents current inrush and mechanical stress on rectifier components, extending service life.
