Voltage monitoring relay, practical protection, to protect equipment from reverse operation

Features:

1. This relay can monitor its own operating voltage (true RMS measurement).

2. 8 types of adjustable rated voltage.

3. The voltage measurement accuracy is no more than 1%.

4. The operating status of the relay is indicated by LED indicators.

5. With its very small size, this relay can be mounted on a 35 mm DIN rail.
