PFS 503N Series

Unlike any other Power Fail simulator 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 sync signal is available to synchronize the NetWave power sources. This is required to keep the mains and NetWave output signal in phase. The PFS 503 can also be used for single phase testing offering a separate DUT output for this purpose.
