A small, lightweight switching power supply unit that has a low power consumption in idle mode and a higher efficiency in operation is often sufficient. Our switched-mode power supply units can be used in the 85-264 VAC range on all standard mains voltages worldwide and are short-circuit proof.
A customized version of a power supply unit is also available on request, e.g. with a main switch, thermal fuse/switch or modified housing shape.

Derating - reduction of the output power
Derating means reducing the output power depending on the ambient conditions. Derating is therefore a recommended protective measure for electronic components and devices to protect them from high temperatures and prevent failures. The power reduction is specified for each power supply unit.
