ThermoKeytek 801-4 IEC-IEEE Burst Generator
The ThermoKeytek 801-4 EFT Generator fully
meets the EFT/Noise TM burst generation specifications of IEC 1000-4-4 (IEC
801-4) 0, as well as the revised ANSI/IEEE C62.41. The Keytek 801-4
incorporates a built-in coupler/decoupler (coupler/filter) for
single-phase ac power lines up to 277V, 50-60 Hz, to 20A . Note: the EFT
may be coupled to one, two or all three ac input lines (including green
ground) individually or simultaneously.
The unit provides the IEC-specified bursts
of 5 ns/50 ns double exponential impulses at a 50 ohm output impedance.
Totally repeatable waveforms, high reliability and long life are key
features of the design . Voltage is adjustable from 250V to 4.4 kV.
Repetition rate meets the IEC and ANSI/IEEE requirements of 5 kHz to 2 kV,
and 2.5 kHz to 4.4 kV. Burst length is from 1 to 20 ms ; burst repetition
period is 0.3s to 5s.
