As of 2016, the EM Test EFT 500N5.8 is a top of the line electrical fast transient (EFT/Burst) generator. A built in 3 phase coupler capable of 690V per line at 32 amps, any DUT can be hooked up and injected with EFT for evaluation and compliance to IEC 61000-4-4, ANSI C62.41, IEC 60601-1-2 and all other test standards requiring an immunity from electrically fast transients.
