Haefely PEFT4010 Overview

Electrical fast transients (EFT) are the most common sources of disturbances in modern electronic circuits. EFT/bursts are caused by the operation of electro-mechanical switches, motors or power distribution switchgears.

The PEFT 4010 instrument contains all the features expected from a top quality EFT generator. Unbeaten performance paired with a high end assembly guarantee a cost effective, long-lasting investment and valuable test results. PEFT 4010 can either be operated by the front panel keys in a stand alone manner or be controlled by PC via RS232 or IEEE 488 as part of a complete EMC test system.

Tests can be performed manually or automatically with predefined test programs. The front panel layout with its large LCD display and the intuitive software are especially designed for self explanatory and safe operation of the instrument. Up to 36 test setups can be programmed and saved on the internal nonvolatile memory.

Bursts are generated according to the related standards IEC 61000-4-4 and EN 61000-4-4. The PEFT 4010 can deliver EFT impulses in different formats including normal, continuous, random and real pulse distribution.

For better handling, the PEFT 4010 is equipped with two grounding connections, one at the front panel and one at the rear panel. This is very helpful in making connections to the ground plane if the PEFT 4010 is used either horizontally or vertically.

With the integrated “Transition Function” Unominal, the spike frequency, the burst duration and the burst period can be varied automatically during a test. Besides this, it is also possible to edit the parameters manually during a test. Besides conventional safety features, the PEFT 4010 contains a separate “Line ON/OFF” switch with which the main supply can be disconnected from the equipment under test.
