Electronic and electrical equipment may be affected by voltage dips, short interruptions and voltage variations of the power supply. Dips and interruptions are caused by faults in the public supply network, in installations or by sudden large change of load. Testing to such phenomena is required to proof that electronic and electrical equipment do not fall into unsafe operation conditions. EM TEST offers a full range of simulators up to 3x690VAC, 100A and DC voltage capability of up to 600V.

The EM TEST PFS 503N Series represents a real three-phase Power Fail simulator. Not only phase-by-phase testing is possible but any combination of phases and all three phases can be simultaneously tested. Herefore the PFS503N Series is equipped with six individually controlled semiconductor switches. Each switch is electronically short-circuit protected.

Additionally the PFS 503N Series is available for nominal currents of up to 100A which is another outstanding and unreached feature for Power Fail testing. The PFS 503N Series offers BNC outputs for individual current monitoring for each phase by means of an oscilloscope. The inrush current can be measured using these BNC outputs. An analog DC signal of 0 to 10V is supplied to drive an external motorised three-phase variac. The PFS 503 can also be used for single phase testing offering a separate DUT output for this purpose.
