5A 12V Overcurrent Protection Sensor Module

LC 5A 12V The Overcurrent Protection AC Current Detection Sensor Module uses a current transformer to collect the AC signal to achieve the relay overcurrent signal output within 0-5A. The relay pulls while overcurrent, and the relay releases while not overcurrent. Users can use the relay COM, NC, and NO three ports to control the external circuit on and off in order to achieve overcurrent protection. Functions: 1. Current detection resolution can change the parameter of resistance parameters; 2. Output over-current switching signal output; 3. The over-current signal setting critical point is adjustable. Using Instructions: By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. As follows: 1. Measured the wire through the current transformer, connect VCC and GND to the DC12V power supply; 2. Adjust the potentiometer. when you hear the sound of the relay pull (can be measured with a multimeter COM and NO to see whether was turned on; is connected to the relay, it means it is activated), then reduce or cut off the current flowing through the tested wire; if the relay release at this time, that over-current protection point has been identified (available to multimeter COM and NC to measurement whether is connected; is connected to the relay, it means it is released). 3. When reducing or cutting off the current flowing through the wire, the relay is not released; you will still need to continue to adjust the potentiometer to find the over-current protection point. Package Includes: 1 x 5A 12V Overcurrent Protection AC Current Detection Sensor Module.
