Fully Remote Controllable Hipot Tester with Contact Check Functionality
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.
A/C Automatic Insulation/Withstanding HiTESTER
Model:
3174
Maker:
HIOKI
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
Specification
Accuracy guaranteed: 1 year.
