Megger AC and ACDC HiPot Testers

These AC and AC/DC High-Pot Testers are designed or safety and ease of operation, and readily adapt to development, maintenance or production testing. Three models are available: two AC and one AC/DC. The AC High-Pot Testers feature a front-panel, NEMA 5-15IR three-prong output receptacle. Booted, alligator-clip output and return probes are also supplied with all models.

Test voltage is continuously adjustable from zero to full output, with a zero-start interlock. Leakage current trip level may be adjusted from 0.3 to 12 mA by a front-panel knob. Push buttons are provided to select one-second or continuous testing, to turn off the high voltage and to reset the instrument. All high-voltage connections are recessed to prevent accidental contact with high voltage.

During testing, high voltage will automatically shut down within 50 ms of arcing or exceeding the preset trip level. Visual and audible alarms alert the operator upon failure.

The instruments also feature an interlock that prevents the high voltage from being applied if the supply ground wire is open or if the hot and neutral wires are interchanged. A TESTER GROUNDED lamp lights to confirm the instrument is connected to a properly grounded power source.

The AC High-Pot Testers will automatically shut down if ground circuit resistance of the test object exceeds 15 ohms at any time during testing. This feature may be bypassed when testing double-insulated devices or when using test probes.

These AC/DC High-Pot Testers provide a slide switch to select either AC or DC test voltage. The slide switch safely covers the output jacks not in use.
