User Manual

STC 550 / 650

Protection

UVP (Under Voltage Protection)

If the voltages fall below a certain tolerance value on the single lines, the PSU automatically switches off.

OVP (Over Voltage Protection)

If the voltages increase above a certain tolerance value on the single lines, the PSU automatically switches off.

SCP (Short-Circuit Protection)

In the case of a short-circuit, this feature prevents damage to the core components of the PSU and its System components.

OPP (Over Power Protection)

If the system is oversized and requires more power from the PSU than it can provide, this protection function is activated.

OCP (Overcurrent Protection)

If the current on a single line is higher than indicated, the PSU automatically switches off.
