The popular ALT-120/60 is the most powerful and full-featured standard aerial lift tester available. This product was primarily designed for testing bucket truck booms and liners per the ANSI 92.2 standard. However, its continuously adjustable dual output voltages, high power rating, and mobility also make it ideal for field testing other high capacitance loads requiring AC withstand testing. This unit is also used for overvoltage AC withstand testing of ISO phase bus, switchgear, circuit breakers, reclosers, vacuum bottles, and hot sticks.

Features:

Continuously adjustable output voltage
Fixed overload, factory set to 120% of rated output current
Zero start and external interlock provision
Three-range voltmeter from dual internal voltage dividers
Dual-range current meter, 0 – 250 ?A and 0-1.0 mA with x1, x10, and x100 multipliers
Guard/ground return circuit
Automatic transit protected meters
Rugged case with cushion grips
Test timer circuit
Simple controls
Hand cart included
