Phase Voltage Monitoring Relay

Phase Voltage Monitoring Relay

Introduction
1. SMS phase voltage monitoring relay is made using SMT technique. It is known for reliable quality, stable performance and compact size.
2. It can be installed by standard din rail and screw.
3. The contact material varies according to inductive load and resistive load.
4. SMS phase voltage monitoring relay is widely used for mobile equipment control such as field device, agricultural equipment and refrigerator car.
5. In order to guarantee safety of human beings, it prevents the equipment such as crane, elevator andescalator from reversing.
6. SMS phase voltage monitoring relay features sensitive three-phase power control
7. Switchover between normal and emergency power.
8. Applicable voltage range: AV380V±10% or AC200-500V.
