Features and Advantages
1. Small ripple factor, stable and reliable voltage output, no noise.
2. With over-voltage, over-current, zero position protection functions, can set value of protection voltage
3. Digital display, can read the data when power on, convenient to supervise output status.
4. With 0.75 times voltage conversion, convenient to test Zinc Oxide arrester.
5. Compact structure, small volume, easy to carry.
