Features:
1. The voltage monitoring relay is used to measure and protect the power supply voltage with phase sequence and phase failure protection, as well as over voltage and undervoltage protection
2. The voltage protection supports self-resetting after a failure, which is very convenient and you can use it without hesitation.
3. Voltage monitoring relay with LCD display, real-time display of working data, easy to read, LED display for relay status, easy to judge.
