Description
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: DC5VOperating 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 DC5V power supply;2. Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on, if connected to the relay means activated), then reduce or cut off the current flowing that 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 measurement whether is connected, if connected to the relay means been released);3. When reduce or cut off the current flowing through the wire , the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point.
