AC AUTOMATIC INSULATION/WITHSTANDING HiTESTER 3174

The AC Automatic Insulation/Withstanding Tester 3174 is a low-cost solution featuring contact check functionality as well as a stabilized power supply to prevent the reduced test reliability that can result from these issues.

Key Features

Continuous testing of insulation (500/1000 V) and withstand voltage (100 VA transformer capacity)
Full remote operation when used in combination with the Safety Test Data Management Software 9267
Save up to 8 test settings each for the withstanding and insulation testing modes
Precise test voltage without power voltage dependency is generated using the PWM method

Model No. (Order Code)

3174

Note: To perform contact checks, please purchase another High Voltage Test Lead 9615 set separately.
