Description

AC 5A Overcurrent Protection module

Features:
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 overcurrent, relay released while not. Users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve 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,
AC 5A Overcurrent Protection module Specifications:
Operating voltage: DC12V
Operating current: <20MA
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 ℃ ~ +85 ℃
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 on the module, connect VCC and GND to DC12V power supply;
2. Adjust the potentiometer, until you hear the sound of the relay pull (can also 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. Turning the pot slightly back to operate your equipment below the cutoff current.
