Product details

Features:
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.
Over-current signal setting critical point is adjustable.

Key Features

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.
Over‑current signal setting critical point is adjustable.

What’s in the box

1 * Module
Functions:
Current detection resolution can change the parameter of resistance parameters.
Output over-current switching signal output.
Over-current signal setting critical point is adjustable.
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, after pull off.
Using Instructions:
By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment can reduce 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, to see if COM and NO was turned on, and 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 (can use multimeter to see if COM and NC was 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.
