PFS 503N Series


PFS 503N Series - Simulator for dips, short interruptions and voltage variations
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 such phenomena is required to proof that electronic and electrical equipment do not fall into unsafe operation conditions.
EMTEST offers a full range of simulators up to 3x690VAC, 100A and DC voltage capability of up to 600V.



Standalone test generator for dips, short interruptions and voltage variation

Full-compliant three-phase system as per IEC 61000-4-11, Ed.2:2004 and IEC 61000-4-34

6 electronic switches, short-circuit protected

Rated voltage up to 3x690V AC, 600V DC

Nominal current up to 100A per phase

DC signal to control external variac

Front panel operation

Standard test routines

USB and GPIB interfaces


PFS 503N Series - The only real three-phase Power Fail simulator
Unlike any other Power Fail simulators, EMTEST PFS 503N series represent 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. PFS503N series is equipped with six individually controlled semiconductor switches.
Each switch is electronically short-circuited protected. Additionally, 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 motorized three-phase variac.
The PFS 503 can also be used for single phase testing offering a separate DUT output for this purpose.
