The Associated Research 5220A DC Hypot tester is used to test new or repaired motors, generators, switchgear, cable, wiring and other electrical and electronic products. It is designed for non-destructive, high voltage direct current testing for both assembly line and field use.

The generally accepted formula for high voltage DC hipot testing potential is to apply 1.6 times the AC operating voltage, plus 1,000 volts. With this standard, the 5220A can be used to test equipment with operating voltages as high as 4,160 volts AC.
