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.

FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA New toy for makers who want to build their own smart home system Overview: The wireless switch supports inching /self-locking mode. You can add the device to the APP eWeLink to remote control connected home appliances or devices. In self-locking mode, you can remote turn on/off connected devices immediately. When in inching mode, you have two wiring ways to select, whether turn on 1s and then auto-off or turn off 1s and then auto-on. Remote control by APP EweLink for iOS and Android. Supported functions include remote on/off, timing schedules, device sharing, group management. The self-lock/inching mode wireless switch has two power supply specification: 5V. No matter which specification you select, they have the same functions. Feature: There are two working modes for the module: inching mode and self-locking mode. Press the self-lock/inching mode button to switch between these two modes. When your module is switched to self-locking mode, you can turn on/off the connected appliance instantly. There is two wiring way. When your module is switched to inching mode, you can press on/off toggle button to turn on or off connected device. There are two kinds of wiring way. The first wiring way is to connect COM and NO with an appliance. In this way, when you press the setting button or APP to turn on, the connected appliance will be turned on for 1s and then auto turned off. The second wiring way is to connect NC and COM with an appliance. In this way, when you press the setting button or APP to turn off, the connected appliance will be turned off for 1s and then auto turned on. LED Indicator: There are 3 LEDs, the led beside self-lock/inching mode button indicates the working mode(on: self-locking mode, off: inching mode). The one beside on/off setting button indicates wifi status(enter pairing status: long press the setting button until led fast blink). Another one below the relay indicates relay on or off status(on: turn on the connected device, off: turn off connected device). Add device to eWeLink: Long press the setting button until the LED beside on/off setting button fast blinking. 1. Android: Add Device->select pairing method according to how the LED blinks->enter WiFi name and password->pairing and register->name device 2. iOS: go to phone setting->WiFi-> select the WiFi starts with ITEAD-********, enter default password to connect:12345678-> go to eWeLink->Add device->->select pairing method according how the LED blinks->enter WiFi name and password->pairing and register->name device Specification: Dimension:70.5mm*27.4mm*23mm Operating current: 5V DC Leds: indicate working mode, wifi status, relay on/off status.
