FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA 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: 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 ￢ﾄﾃ ~ +85 ￢ﾄﾃ 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.

Feature: We all know what an AC dimmer is; for those who don’t, it’s a kind of a circuit which can control the amount of AC voltage to be given to any device. You can see them in a fan regulator or a light dimmer switch. It's good for a smart home if you need to turn the lighting on and off slowly. The lamp is slow damped, this creates a pleasant effect. Also can control AC/DC motor, electric pump, tools. Pulse Skip Modulation: Another way of doing this is by Pulse Skip Modulation. With PSM, one or more full cycles (sinuswaves) are transferred to the load and then one or more cycles are not. Though effective, it is not a good way to dim lights as there is a chance for flickering. Though it might be tempting, in PSM one should always allow a full sinuswave to be passed to the load, not a half sinus as in that case the load will be fed factually from DC which is not a good thing for most AC loads. The difference between leading edge cutting and PSM is mainly in the software: in both cases one will need a circuit that detects the zero crossing and that can control a triac. A circuit that can do this is easy to build: The zero crossing is directly derived from the rectified mains AC lines – via an optocoupler of course- and gives a signal every time the wave goes through zero. Because the sine wave first goes through double phased rectification, the zero-crossing signal is given regardless whether the sinus wave goes up through zero or down through zero. This signal then can be used to trigger an interrupt in the Arduino. Package includes: 3 x AC Light Dimmer Module
