Dual Output Power Supply (220V dual-circuit 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.
This Dual Output Power Supply board is a highly efficient and flexible power solution, specifically designed to meet the demand for stable simultaneous power supply to multiple devices. Its core advantage lies in its dual independent output design, where two separate power channels operate independently, enabling it to provide power support to two devices of different specifications at the same time. This eliminates the need for additional power adapters, significantly simplifying the power supply layout, saving space, and reducing equipment matching costs. In terms of output specifications, the power supply board covers three commonly used low-voltage parameters: 7.5V/2.4A, 9V/2A, and 12V/1.5A, making it widely compatible with a variety of low-voltage electronic devices such as small motors, sensors, industrial control modules, routers, switches, LED drivers, small audio equipment, surveillance cameras, mini fans, and low-voltage light strips. Whether it is for the operation of daily electronic devices or applications in small industrial scenarios, it can deliver precisely matched power output. Additionally, the power supply board is equipped with reliable over-current and over-voltage protection mechanisms. It can respond quickly to abnormal current or voltage fluctuations in connected devices, effectively preventing damage to both the power supply board itself and the connected equipment due to unexpected situations, fundamentally ensuring the safety and stability of the power supply system. It is an ideal power supply choice that combines practicality and safety.

Dual output supplies are indispensable on every engineer's bench. They are perfect for powering operational amplifier (op-amp) circuits, requiring both positive and negative voltage rails. They also allow developers to independently test and debug different sections of a complex prototype, such as powering a microcontroller with one channel and its sensor array with the other.
In academic settings, these power supplies are fundamental for teaching core electronics concepts. Students can experiment with analog and digital circuit design, observing firsthand how components behave with different voltage biases. The ability to provide both positive and negative voltages is crucial for understanding amplifiers, oscillators, and other foundational circuits.
For quality control, dual output models are used to stress-test components and assemblies. One channel can simulate a primary power source, while the other injects a noise signal or simulates a fluctuating secondary source. This verifies the device's stability, ripple rejection, and overall robustness under non-ideal operating conditions.
Many communication and high-fidelity audio systems rely on balanced symmetrical voltages. A dual output power supply can provide the necessary ±12V or ±15V rails for analog mixers, RF modules, and signal processing equipment. This ensures clean power for sensitive analog stages, minimizing noise and distortion.
Makers and hobbyists benefit greatly from the flexibility of a dual output supply. It can power a wide array of projects without needing multiple single-channel units. For instance, one channel can power the logic of a robotic arm (e.g., +5V), while the other drives the servo or DC motors (e.g., +12V), all from a single, programmable instrument.
It is suitable for devices that require AC to DC conversion, such as routers, switches, 3C products, power distribution systems, etc.
The 220V two-way power supply board 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.
220V dual circuit 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 Dual Output 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 Output 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.
