Single Phase Voltage Monitoring Relay

Protect electrical equipment and motors from over-voltage and under-oltage. Normal/emergency power supply switching.

GEYA Single Phase Monitoring Relay is a device intended for effective voltage automatic control and such equipment as home appliances and other devices in home and offices protection.

It is designed for the protection of single phase load un-allowable voltage variations in the mains. They have a wide range of adjustments, including power on time delay for protection on refrigerating, compressor and air conditioning equipment.

GEYA Single Phase Voltage Monitoring Relay provides for automatic load energizing after voltage parameters recovery within predetermines time relay.

The relays are compact in size and weight. They can be utilized both as independent switching devices and as controls for other switching devices, like magnetic starters.

GEYA Single Phase Monitoring Relay performs the function of protection against voltage drops.

It is designed to de-energize an industrial appliance single phase in case of inadmissible voltage variations in the mains with subsequent automatic re-energizing after the circuit parameters recovery.

Loads are connected to the relay either directly via relay terminals or through a magnetic starter, depending on the wattage.
