The High Voltage ALT-120/60 is 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 7.2 kVA of output power with the draw of 3.6 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.
