Contact for Lead Time

Production delay is expected due to the worldwide component shortages. Please contact a Hioki representative for details.

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

Product Warranty Period: 3 years
