Power-on surge control

[Messtechniker]

With so many switching power supplies*  in the lab, switching these all on at once caused tripping of the automatic circuit breaker ever so often. Solved the problem by fitting a power-on surge limiter – see pic – downsteam of the main switch. Mine is an EBN 2 made by Schalk for hat rails. Works.
