Output

The output provides a SELV/PELV nominal voltage, which is electrically isolated from the input voltage and is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

The output is electronically protected against overload, no-load and short-circuits. In case of a protection event, audible noise may occur.

This is the maximum output voltage that can occur

at the clockwise end position of the potentiometer due to tolerances. It is not guaranteed value which can be achieved.

The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is switched on or off. The absorbed energy can be calculated using the built-in, large-size output capacitor.
