HVA68-2

Double Power VLF / DC Hipot Tester

> > HVA68-2

Consider the HVA68-2 VLF/DC Hipot Tester a turbocharged HVA60 with double the output power capacity! ‍

For customers that want to maintain optimum output frequency with pure undistorted sinewave when testing extremely long cables or complex cable networks, the HVA68-2 model is the unit of choice.
‍

Powerful 2.0 μF @ 0.1 Hz @ 44 kV_rms(HVA68-2)
vs. 1.0 μF @ 0.1 Hz @ 44 kV_rms (HVA60)

‍

The HVA68-2 model delivers twice the power with identical size, weight, and footprint as the ever popular HVA60. This market-leading high voltage test instrument has the same familiar HVA user interface and standard HV cables, connectors, etc.

Test reports are downloaded to the instrument’s internal memory or to a USB flash drive. As with all HVA units, you get fully automatic test sequences, accurate digital RMS metering, and integrated storage of test results that can be viewed with freely available HVA Control Center Software.
