FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA 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: DC12V Operating current: Operating frequency range: 20Hz ~ 400Hz Output mode: switch signal output Maximum detection wire diameter: 5.2mm Mounting hole: hole diameter is 3mm, hole distance is 52.5mm Operating environment: -40 ￢ﾄﾃ ~ +85 ￢ﾄﾃ The current detection range:AC0.3A-5A Board 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 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.
