Phase Sequence Phase Failure Voltage Analogue Adjustable Protection Relay (With Neutral Wire)
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 same as adjusted, relay led switches on and relay pulls. In this cases contact out is(NO)3 pole. When the volage values are avnormal, relay releases and led is switched off after waiting till the setted time is up. In this case contact out is (NC)1. GK-04FN type voltage controller relay doesn't work if the phase sequence is incorrect.MaintenanceSwitch off the device and release from connections. Clean the trunk of device with a swab. Don't use any conductor or chemical might damage the device. Make sure device works after cleaning.WarningsPlease use the device according to the manual. Don’t use the device in wet. Include a switch and circuit breaker in the assembly. Put the switch and circuit breaker nearby the device, operator can reach easily. Mark the switch and circuit breaker as releasing connection for device.SpecificationsOperating Voltage(Un)....: 3 x 380V AC + Neutral Operating Frequency.......: 50/60 Hz.
