Over Current Protection (OCP): installed at each rail
Over Load Protection (OLP): typical 120% max. load, fully protected against output overload or short circuit
Over Voltage Protection (OVP): built-in at all outputs
Status LED [POWER] means valid input voltage
[FAULT] means a critical fault
Earth leakage <0.5 mA @ 230 VAC <0.5 mA @ 48 VDC <0.5 mA @ 24 VDC
