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: <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 , 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.

Package Included:
