Testing capabilities
- Continuously adjustable test voltage from zero to the selected model’s rated output
- Combined AC and DC hipot testing in one benchtop instrument
- Output-connected voltmeter measures voltage regardless of output loading
- Adjustable overload from 10 to 110% of rated output current
- Zero-start interlock prevents high voltage from being energized unless the voltage control is at zero
- Audible and visual overload alarms; shielded output cable
- Shorting solenoid grounds the output cable and test object when high voltage is turned off
- Mountable in a standard 19-inch rack
- Photo and downloadable manufacturer datasheet are from a legacy HD100 publication; confirm the current configuration and ratings with our technical team
Manufacturer-published capabilities. Available tests depend on the selected configuration and accessories. Confirm suitability, availability and pricing with our technical team.
