3Pcs DC 12V 5A Overcurrent Protection Sensor Module AC Current Detection Relay Module Switch Output

Features LC 5A Over current protection Sensor module uses current transformer to collect the AC signal to achieve the relay over current signal output within 0 5A Relay pull while over current relay released while not over current Users can use the relay COM NC NO three ports to control the external circuit on and off in order to achieve over current protection Functions Current detection resolution can change the parameter of resistance parameters Output over current switching signal output Over current signal setting critical point adjustable Specifications Operating voltage DC12VOperating current 20MAOperating frequency range 20Hz 400HzOutput mode switch signal outputMaximum detection wire diameter 5 2mmMounting hole hole diameter is 3mm hole distance is 52 5mmOperating environment 40 ℃ 85 ℃The current detection range AC0 3A 5ABoard size 38 44mm The Board Description VCC Operating voltage positive GND Operating voltage negative NO Normally open the relay pulls before the NO and COM disconnect short circuit after the suction COM common relay common interface NC Normally closed the relay before the NC and COM short circuit pull off after Using Instructions By setting the potentiometer to set the overcurrent protection point the clockwise adjustment reduces the detection current As bellows 1 Measured the wire through the current transformer connect VCC and GND to DC12V power supply 2 Adjust the potentiometer when you hear t
