General
Voltage Controller Relays are designed to avoid the failures of network voltage for the devices which have sensitive working voltage.
Usage and Working Principle
Make the connections according to the diagram. Set the device according to the required electrical charge. When the power is on if the voltages are the same as adjusted, relay led switches on and relay pulls. In this case, contact out is(NO)3 pole. When the voltage values are normal, the relay releases and the led is switched off after waiting till the set time is up. In this case, contact out is (NC)1.
GK-04 type has related led for high and low voltage and Phase failure.
