The PFT-503CM and PFT-503CMF are from our popular PFT Series of field portable AC hipot test sets. These hipots provide continuously adjustable AC voltage used for a pass/fail, AC over-voltage withstand test on high voltage apparatus, like switchgear, circuit breakers, reclosers, vacuum bottles, hot sticks, bus duct, and any other apparatus needing an AC test voltage.
The PFT Series offers the most field portable, affordable, and easiest to operate AC hipots at this voltage and power. A gapped core transformer for up to 3 kVA of output power with the draw of only 1.5 kVA so the hipot can be powered by a standard 120Vac or 230Vac input. Equipped with a two-range voltmeter, three-range current meter and guard circuit for precise leakage current measurements.
