Sensor Arus AC 5V 12V 12V Modul Relay Presisi Tinggi Saat Ini ZMCT103C Transformer 5A Modul Sensor Papan Deteksi
1. Overview
LC 5A Over-current protection Sensor moduleuses 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.
2.The function and characteristics
1, Operating voltage: DC12V;
2, Operating current: <20MA;
3, Operating frequency range: 20Hz ~ 400Hz
4, Output mode: switch signal output;
5, Maximum detection wire diameter: 5.2mm;
6, Mounting hole: hole diameter is 3mm, hole distance is 52.5mm;
7, Operatingenvironment: -40 ℃ ~ +85 ℃;
8, Current detection resolution can change the parameter of resistance parameters;
9, Output over-current switching signal output;
10, Over-current signal setting critical point adjustable, the current detection range AC0.3A-5A;
3. Introduced the hardware and instructions
Board size: 38 * 44mm
The board function description:
The interface description:
VCC: Operating voltage positive;
GND:Operating voltagenegative;
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.
