SONOFF® Dual Channel WIFI APP Remote Control Switch Socket Module 250V For Smart Home (Sonoff dual ch switch)
Description:

Sonoff Dual is a WiFi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick WiFi access, remote control through APP EweLink.

In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.

Works With Amazon Alexa

You can ask Alexa to turn on/off Sonoff Dual.

Standard voice control commands phrases for Sonoff Dual (if you just say the device name, Alexa will turn on/off all the 2 gangs immediately):

Alexa, turn on {deviceName}
Alexa, turn off {deviceName}

Alexa, turn on {deviceName} {gangName}
Alexa, turn off {deviceName} {gangName}

Explanation: if the device name of your Sonoff Dual is "My Switch", the gang name is "Gang 1", then you can control with "Alexa, turn on My Switch Gang 1".

110/220V 60W 12V 5A Miniature Switching Power Supply (Miniature 12V 5A power supply)
Description:


A switching power supply is one of the two major types of power supply design utilized in electronics products. These power supplies are characterized by the use of precise switching that allows for designs to accommodate DC to DC, DC to AC, AC to DC and frequency conversions.
In switching power supply designs, the input voltage is no longer reduced; instead, it's rectified and filtered at the input. Then the voltage goes through a chopper, which converts it into a high-frequency pulse train. Before the voltage reaches the output, it's filtered and rectified once again.

  • Input: AC100-240V 50/60Hz
  • Output: DC 12V
  • Shell Material: Aluminum
  • Safety Compliance: CCC / CE /Rohs
  • High price-effective, reliability with industry standards
  • 100% full load burn-in test
  • Universal AC input / full range
  • It's good quality & high performance
  • Cooling by free air convection.
  • Not suggested for use in a bathroom
  • Built-in over voltage, over current, and short circuit protection
  • Working Temperature: 0~40℃
  • Storage Temperature: -20~60℃
  • Ambient Humidity:  0~95% Non-Condensation


Features
 
  • Switch power supply, convert AC 110V/240V to 12V
  • Wide input voltage range, steady and precise output voltage.
  • Shortage protection, overload protection over voltage protection.
  • Widely used as the power adapter for Led strip, LED display, billboard, industrial equipment, etc.
