Current detection resolution can change the parameter of resistance parameters.
Output over-current switching signal output.
Over-current signal setting critical point is adjustable.
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, after pull off.
By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment can reduce the detection current.
Measured the wire through the current transformer , connect VCC and GND to DC12V power supply;
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.
Over-current signal setting criticals point is adjustable.
Users can use the relay COM, NC, NO three port to control the external circuit on and off, in order to achieve over-current protection.
