HVA120

VLF / DC Hipot Tester

> > HVA120

This single-piece design is an easy set up in the field. The associated reporting software has the versatility to not only report test results but also creates and loads test sequences onto the unit itself so you can complete your test with one click!

This unit has a real time oscilloscope display that gives other test parameters such as load capacitance and charging current and its user interface is extremely straightforward with a single rotary control and intuitive menu options.

The HVA120 unit can store up to 50 test reports that are accessible either through the optional USB interface or the standard RS232 connection. Simplify and automate your cable testing experience with this HVA Series system!
