Features:
1. It is used for power supply voltage measurement and protection, with phase sequence and phase failure protection, overvoltage and undervoltage protection.
2. The voltage relay supports self-resetting after failure, which is very practical and you can use it with confidence.
3. With LCD display, real-time display of working data, easy to read, LED indication for relay status, easy to judge.
4. The product is small in size, installed on a standard 35mm guide rail, and uses high-quality pure copper wiring terminals, the wiring is fastened and not easy to loose, and the service life is long.
5. Scope of application: used to control mobile equipment, field equipment, agricultural equipment, refrigerated vehicles, control and protect personnel and equipment from the consequences of reverse branches.
