Averaging of the inductive energy supplied per switching
operation from the supply line to the device input
Switching off of switching paths, display OVL
Switching off and on again using mains switch
Note: The incoming energy can be minimized by a short cable,
arranged for low-inductance.
Max. switching frequency exceeded

Reset
Frequency present at the control input
Switching off of switching paths, display OVL
Reduction in the switching frequency below the permissible
value with consideration of a hysteresis of typically 5 kHz
Excessive temperature

Temperatures of the power components
Stage 1: Increase in fan speed
Stage 2: Switching off of switching paths, display OVL
Switching off and on again using mains switch following
appropriate cooling period
Power switch is not reverse polarity protected!
Reverse polarity voltage applied to the input or output can
damage the unit from excess current or thermal overload.
