EFT 500

EFT/burst generator pulse 5/50ns

EFT500 – an EFT/Burst generator – is an intelligent solution
offering exactly what you need for full-compliance immunity
tests against Electrical/Fast transients phenomena. The distinct
operation features, convenient DUT connection facilities, a
clearly arranged menu structure and display philosophy as well
as the pre-programmed standard test routines make testing
easy, reliable and safe. 

Extendable by a variety of test accessories the EFT 500 is a
universal equipment for abroad range of recommendations even
for three-phase applications up to 100A
