Dual DC Power Supply is a power supply board that converts alternating current (AC) into direct current (DC) and outputs multiple voltages. It usually includes two outputs and is suitable for various electronic devices and power needs.
The main function of Dual DC Power Supply is to convert 220V alternating current (AC) into multiple direct currents (DC) of different voltages for use by equipment. It can effectively provide stable power for weak current wiring boxes, routers, switches, 3C products, etc. Common applications include AC to DC power supply and AC to DC converter to help achieve the normal operation of equipment.
Wide input voltage range: supports input voltage range of AC100~240V, adapting to a variety of power supply environments.
High efficiency: working efficiency is higher than 80%, ensuring high-efficiency conversion.
Multiple protection functions: built-in overvoltage protection, short circuit protection, overload protection and temperature protection to improve equipment safety.
Working temperature: It can work normally in an environment of -20℃～+50℃, adapting to different usage environments.
Compact size: The product size is 120*20*22 ±0.2mm, which is easy to install in a compact space.
High stability: Due to the built-in multiple protection functions, the 220V dual power supply has high stability and reliability, reducing the risk of power failure.
Strong flexibility: Supports multiple output voltages (7.5V2.4A, 9V2A, 12V1.5A), which can provide the required power for different devices.
Energy saving and high efficiency: Working efficiency above 80% means less energy waste and lower electricity bills.
Wide application: Applicable to multiple fields, such as routers, switches, weak current wiring boxes and other electronic devices.

Industrial and home applications: Applicable to home or industrial equipment that requires efficient and safe power supply.
Power system: As a Dual DC Power Supply, it is widely used in systems that require dual-circuit power supply.
It is suitable for devices that require AC to DC conversion, such as routers, switches, 3C products, power distribution systems, etc.
The Dual DC Power Supply has built-in overvoltage protection, short circuit protection, overload protection and temperature protection to ensure that the power supply automatically cuts off under abnormal conditions to prevent damage to the equipment.
The output voltage has several fixed standard options, such as 7.5V2.4A, 9V2A and 12V1.5A, which cannot be adjusted, but the appropriate version can be selected as needed.
Yes, the operating temperature range of the 220V power supply board is -20℃～+50℃, which can adapt to the use requirements in different environments.
During installation, make sure the input is connected to an AC 220V power supply and the output is connected to a device that requires DC power. The installation process should comply with the 220V power supply installation standard and ensure that the device operates in an appropriate temperature and humidity environment.
Dual DC Power Supply usually supports a single input of AC 220V and outputs multiple voltages (such as 7.5V, 9V, 12V, etc.), and there is no separate multiple input method.
Due to the built-in temperature protection function, the 220V Two Way Power Supply will not overheat under normal working conditions. If the device overheats, the temperature protection mechanism will automatically start to prevent damage.
The Dual DC Power Supply has a long service life and can withstand storage temperatures up to 80°C. It is suitable for long-term stable operation, especially in industrial applications.
