1. Description
1.1 Introduction
The PEFT Junior test system, enables electromagnetic immunity testing in accordance with the
standard IEC 1000-4-4 (IEC 801-4).
The built in single phase mains filter enables coupling of EFT / Burst into the EUT mains supply
with minimum disturbance to the general mains.
HAEFELY
CONTROL UNIT
HAEFELY
PEFT.1
Fig. 1.1
The equipment is controlled by an integrated microprocessor control unit ( P90 ).
In order to conduct three phase tests in accordance with the standard IEC 1000-4-4, it is
necessary to use an external coupling filter. For example the FP-EFT 32.1 is a three phase filter
that can be controlled directly from the PEFT Junior mainframe.
Tests in IEC 1000-4-4 which require coupling of the EFT / Burst into data and communication
lines, can be achieved using the capacitive coupling clamp type IP4A.
The test system can be made fully automatic, by using the optional interface type RC 730 for
RS232 and IEEE communication with the WinPATS software package.
