-LC 5A 12V Overcurrent Protection AC Current Detection Sensor Module uses a current transformer to gather the AC sign to reap the relay over-contemporary sign output inside 0-5A.
-Relay pull at the same time as over-current, relay released whilst no longer over-modern-day.
Users can use the relay COM; NC, NO 3 ports to govern the external circuit on and off, that allows you to gain over-contemporary safety.
Functions:
Current detection resolution can trade the parameter of resistance parameters;
Output over-modern-day switching signal output;
The over-cutting-edge sign placing important point adjustable.
Using Instructions:
By putting the potentiometer to set the overcurrent protection factor, the clockwise adjustment reduces the detection modern-day.
As bellows:
Measured the cord via the present day transformer, connect VCC and GND to the DC12V energy supply;
Adjust the potentiometer, while you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether turned into turned on; is attached to the relay manner activated), then lessen or reduce off the contemporary flowing that via the tested wire; if the relay release right now that over-contemporary protection factor has been identified (to be had to multimeter COM and NC dimension whether or not is attached; is hooked up to the relay approach it release);
When lessen or reduce off the present day flowing through the wire; the relay isn't released, will nevertheless need to keep to adjust the potentiometer to locate the over-present day safety point."

OVERVIEW:
LC 5A Over-current protection Sensor module uses a 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
