The ALT 300(F) was primarily designed for testing bucket truck booms and liners. 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
• Dual-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
• Transit protected meters
