SINGLE PHASE VOLTAGE CONTROL RELAY

The device is used for protection of single phase loads from electrical power supply disturbances. It provides protection of the phase against under-voltage (adjustable, 170-215VAC) and over-voltage (pre-adjusted), as well as complete loss of the phase or the neutral.

The device is used for protection of single phase loads from electrical power supply disturbances. It provides protection of the phase against under-voltage (adjustable, 170-215VAC) and over-voltage (pre-adjusted), as well as complete loss of the phase or the neutral.

It is installed in an electrical panel on a standard relay socket.

The output relay is activated when the power supply voltage does not diverge from its nominal value more than the lower limit adjusted by the user or the the upper limit preset to 250V AC. In any other case, as well as in case of complete loss of the phase or of the neutral, the relay is deactivated. The adjustment refers to the lower limit of the phase, while the upper limit is preset to 250V AC.

It is a digital device using a microcontroller.
