The ETI Precision Model PI 250, particularly the PI-250 Gen2, is a portable high-current test set designed for electrical testing.
The PI-250 Gen2 generates continuous current of 250 amps with peak maximum output 750 amps through a breaker and 1000 amps into a short, all on 120 VAC supplies. The unit weighs only 38 pounds, allowing easy mobility. Basic operation is very simple, and the proven instrumentation provides optimal output control and measurement.
