Voltage relay CP-710

Single-phase. With a time lock.
The CP-710 voltage relay is used to control the voltage of a single-phase network and to protect a single-phase receiver against the effects of voltage increase or decrease beyond the set values.
Action
Lower (U1) and upper (U2) voltage threshold is set with potentiometers. This is called voltage window, within the limits of which there may be changes in the supply voltage that will not trigger the relay. The correct voltage of the receiver is indicated by the lighting of the yellow LED (contact position 7-10). Changing the supply voltage above or below the set voltage thresholds will activate the relay (switching the contact to position 7-12). The voltage drop below the set U1 value is signaled by the lighting of the red LED (U1). The
