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.

Specifications

• Input Voltage:  AC110V/220V±15%
• Ouput Voltage: DC 12V
• Output Current:5A
• Shell Material: Metal case
• Safety Compliance: FCC / CE
• High price-effective, reliability with industry standards
• Built-in over voltage, over current, and short circuit protection
• Working Temperature: 0~40C
• Storage Temperature: -20~60C
• 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.

• 10A 28VDC

To check compatibility of a new remote with the receiver. Simply press the button on the remote, if the receiver flashes, but does not Triger the relay. The remote will be compatible, and you can start the programing process

To add a remote, press the button on receiver momentarily. The red light will come on. Then press the button on the remote that you want to program in. The red light will start flashing. After 4 flashes in will stop, and the button will be programmed in.

For the setting to take effect, the board needs to be disconnected from it’s power supply. The bellow settings will be done to the 3 headers and bridge pin on the receiver board, above the push button.

• With the header removed, the On button will switch the relay on, and the off button will in turn switch the relay off.
• With the header on Pin 1-2. Both Buttons will become momentary. And only hold the relay in place as long as they are pressed in.
• With the header on Pin 2-3. Each button will be able to switch the relay on and off individually. You will however not be able to switch the button off with the “off” button, if you switched it on with the “on” button. And vise versa.
