INSULATION / WITHSTANDING HiTESTER 3159-02

Perform Insulation Resistance and Withstand Voltage Testing in a Single Series

The Hioki electrical safety testers are designed for insulation resistance and voltage withstand testing of electrical devices and components according to various safety standards. The 3159 tests insulation resistance at 500 V or 1000 V and withstand voltage of up to 500 VA in sequence.

Key Features

  • Continuous testing of insulation (500 V/1000 V) and withstand voltage (500 VA transformer capacity)
  • Insulation to withstand series test or withstand to insulation series test at auto mode, or individual test at manual mode
  • Save up to 10 test settings each for the withstanding and insulation testing modes
  • External I/O, RS-232C interface, Status output (relay contacts)

Model No. (Order Code)

3159-02 For 220V power supplies only
