Features and Benefits

The ALT-210/50 and ALT-210/50F from our ALT Series of field portable AC hipot test sets are primarily designed for testing the dielectric strength of aerial lifts, booms, bucket trucks and liners per the ANSI 92.2 standard. With a continuously adjustable AC voltage, 2 range voltmeter, multi range current meter and built in timer, the ALT Series are also a great choice for a pass/fail, AC over-voltage withstand testing on larger capacitive loads such as switchgear, buss duct or other substation apparatus. A gapped core transformer for up to 7 kVA of output power with the draw of 3.5 kVA so the hipot can be powered by a 30A, 120Vac or 15A, 230Vac input. For lower power requirements please see our PFT Series and ABT Series. For higher power requirements see our FPA, HPA and PAR lines.
