PFS 503N Series - The only real three-phase Power Fail simulator
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 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.
Operation
Easy to operate
Front panel menu and function keys enable the user to program his test routines quickly and accurately. The cursor allows fast control of all test parameters of the programmed routine, thus test procedures are simplified and confidence is generated that every step is carried out correctly.
Software
iec.control Software for Control and Documentation
Software PFS 503N
Outstanding user convenience, clearly structured windows and operation features and the EM TEST standards library along with the flexibility to generate user specific test sequences very easily are the main features of iec.control software. The software is automatically configured according to the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements.
iec.control is supported by Windows 2000, Windows XP, Windows Vista and Windows 7. Remote control is achieved either via USB or GPIB. iec.control supports a wide range of GPIB cards of National Instruments.
Auxiliary Devices
Tapped autotransformer V3P40xxDS for testing three-phase dips and interruptions
The tapped autotransformers of the V3P40xxDS series provide the fixed voltage levels as per IEC 61000-4-11 Ed.2:2004 and IEC 61000-4-34. These transformers can easily be configured for both delta connection and star connection to fully cover and comply to the test requirements as per IEC 61000-4-11, Ed.2:2004.
Motorised variac MV3P40xxDS three-phase Power Fail tests
A motorised variac is required to set the reduced voltage levels to perform voltage dips as per IEC 61000-4-11 Ed.2:2004 and IEC 61000-4-34. The voltage level is set by means of an analog output signal provided by the Power Fail simulator to any level between 0V and the maximum voltage of the variac. The variac solution also provides capability to perform overvoltage tests.

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 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.
