AC and AC/DC High-Pot Testers AC and AC/DC High-pot Testers n Rapid production line testing to latest UL standards n Extra safety features n Rugged design for ease of portability DESCRIPTION APPLICATIONS AC and AC/DC High-Pot Testers available from Megger are These portable instruments are used to test the dielectric designed for safety and ease of operation, and readily adapt strength of electrical insulation and the ground circuit to development, maintenance or production testing. Three continuity of three-wire appliances and other devices. models are available: two ac and one ac/dc. The AC High-Pot Biddle High-Pot Testers comply with most existing UL Testers feature a front-panel, NEMA 5-15R three-prong requirements for dielectric withstand testing, including: output receptacle. Booted, alligator-clip output and return n UL 544 Electric Medical and Dental Equipment probes are also supplied with all models. n UL 982 Motor-Operated Household Food Preparing Test voltage is continuously adjustable from zero to full Machines output, with a zero-start interlock. Leakage current trip n level may be adjusted from 0.3 to 12 mA by a front-panel UL 1026 Electric Household Cooking and Serving knob. Pushbuttons are provided to select one-second or Appliances continuous testing, to turn off the high voltage and to reset n UL 1270 Radio Receivers, Audio Systems, and the instrument. All high-voltage connections are recessed Accessories to prevent accidental contact with high voltage. During testing, high voltage will automatically shut down FEATURES AND BENEFITS within 50 ms of arcing or exceeding the preset trip level. n Ground continuity check of three-wire devices with Visual and audible alarms alert the operator upon failure. high-voltage interlock (ac models only) The instruments also feature an interlock that prevents the n Front-panel adjustable leakage current trip from 0.3 to high voltage from being applied if the supply ground wire 12 mA is open or if the hot and neutral wires are interchanged. A Tester Grounded lamp lights to confirm the instrument is n One-second or continuous testing connected to a properly grounded power source. n Automatic failure shutdown, with visual and audible The AC High-Pot Testers will automatically shut down if alarms ground circuit resistance of the test object exceeds 15 n Recessed high-voltage connections ohms at any time during testing. This feature may be bypassed when testing double-insulated devices or when n Front-panel NEMA 5-15R three-prong receptacle on ac using test probes. The AC/DC High-Pot Tester provides a models slide switch to select either ac or dc test voltage. The slide n Zero start/reset in event of failure switch safely covers the output jacks not in use. n Meets UL 120-k requirementAC and AC/DC High-pot Testers SPECIFICATIONS CAT. NO.
