General Information
GDYD series AC/DC hipot test set is composed of manual control unit and AC/DC Dry testing transformer(HV unit) which output AC/DC voltage smoothly.Meanwhile,it has many monitoring and protection functions.
Features
- Digital display meters mounted on the panel.
- Monitoring HV side voltage, HV side current, LV side current and indicator of zero, power, working start, timing.
- Over-current protection, zero-starting protection, sound and light alarm.
- With new type time relay, time range is more wider (1S ~ 99H).
- Using the latest current relay, more accurate and reliable.
- Light weight, small size, easy to move.
