Digital socket voltage relay MRVs-16 is designed to automatically disconnect the load connected through it if the voltage value in the power grid exceeds the set limits. The device is controlled by a microcontroller that analyzes the voltage in the power grid and displays its effective value on a digital indicator. Load switching is carried out by an electromagnetic relay. The permissible disconnection limits and the turn-on delay time are set by the user using buttons. Values are saved in non-volatile memory.
Advantages of the MRVs-16 EKF PROxima digital socket voltage relay:
• Minimum and maximum voltage limits can be set.
• Manual on/off via button.
• Designed for switching a current of 16 A.
