DIN-rail power supply manufacturer PULS has carried out extreme testing of its QT40 3-phase units by subjecting them to simulated lightning strikes.


The test was carried out using a Marx generator producing a voltage of 500kV over a distance of 0.5 metres. This generated a series of man-made lightning bolts of up to 4kA which hit the power supplies in two separate tests. The first strike was directed into the housing of the unit while the second strike hit the input (L1 – L3) of the QT40. Despite being subjected to such extreme conditions the power supplies continued to work normally.

The PULS QT 40 is ideally suited to industrial bulk power applications such as control systems for large electric motors powering production equipment, conveyors, machine tools, etc.
