Bursts or EFTs (electrical fast transients) are caused by operation of electro-mechanical switches, motors and distribution switch-gear connected to the power distribution network. A typical burst consists of a large number of recurring impulses at high frequency for a short time period.

To cover EFT/Burst test requirements from 100V to 8kV, we offer two basic stand-alone products, PEFT 4010 and PEFT 8010. EFT/Burst tests up to 4.2kV can also be carried out with the Haefely EMC compact test station ECOMPACT 4.

All our EFT/Burst generators are 100% compliant to the latest standards, including the IEC/EN 61000-4-4 edition 2, which is mandatory from October 2007.

EFT Verification Attenuator Set According to the latest changes in the IEC/EN 61000-4-4 edition 2 standard, which is mandatory since October 2007, verification of the burst waveform is required through a 50 and 1000 ohm load. The Haefely EMC EFT Verification set includes all neccessary attenuators and additional cabling and documentation, that allow users to connect to comercial oscilloscopes and verify the waveshape as required by the latest standard. To verify impulses at the CDN output, special adapters can be used together with the attenuators. .

WinFEAT&R Software The WinFEAT&R software is the latest generation of control and reporting software, based on a modern Drag and Drop concept, which offers such simplicity of use, that even users with minimum technical experience, will by carrying out tests in no time. This unique software allows users to run user specified or pre-defined tests according to the latest standards, and monitors and displays real time output current and voltage values. The software runs under all latest Microsoft Windows versions and is compatible with all stand alone Haefely EMC test generators.

IEEE 488 interface GPIB interface board for the PEFT4010 mainframe

Fiber optic interface Fiber optic interface / RS232 converter used to connect the ESD generator PESD1610 with PEFT4010 mainframe PESD 1610 - ESD generator For more information see in the ESD (electrostatic discharge testers) product line.



Real Burst Additional circuit boards can be fitted to the PEFT 4010, enabling it to produce burst packets as they occur in reality, that is with simultaneously varying frequency and amplitudes. Two frequency options can be added, 5KHz and 100KHz.

Remote Control Unit When PEFT 4010 is operated on a floor mounted Ground Reference Plane, access to the instrument front panel may not be so convenient. The Easy Control, enables use of the PEFT 4010 when the instrument front panel is not visible or inconveniently placed.
