MEANWELL PS-25-12 25W single-output switching power supplies

Here is an English introduction to the MEANWELL PS-25-12 25W single - output switching power supply:

The MEANWELL PS-25-12 is a high - quality single - output switching power supply designed to meet the power requirements of various electronic devices with reliability and efficiency.

Electrical Specifications

• Input Voltage: It accepts a wide input voltage range of 90 - 264VAC, allowing it to be used in different regions and power grid conditions. This wide range ensures stable operation even with significant input voltage fluctuations.

• Output Characteristics: The power supply provides a stable 12VDC output voltage. With a maximum output current of 2.08A, it can deliver a rated power of 25W. The output has low ripple and noise, typically within 100mVp - p, which is crucial for ensuring the stable operation of sensitive electronic equipment. The voltage regulation is excellent, with both line regulation and load regulation within ±0.5%. This means that the output voltage remains highly stable under different input voltages and load conditions.

Protection Functions

• Overload Protection: Equipped with overload protection, the power supply will automatically detect and respond when the output power exceeds the rated value. Usually, when the output power reaches around 28 - 35W, the protection circuit will be activated. It adopts the hiccup mode, which shuts down the power supply when an overload occurs and attempts to recover once the overload condition is removed. This protects both the power supply and the connected devices from damage due to excessive power consumption.

• Over - Voltage Protection: The over - voltage protection is designed to operate when the output voltage reaches 13.5 - 16V. If the output voltage exceeds this range, the power supply will enter a protection state and then automatically recover after the fault is resolved. This feature safeguards the connected devices from the risk of over - voltage, which could otherwise cause damage or malfunctions.

• Short - Circuit Protection: In the event of a short - circuit at the output, the power supply has a built - in short - circuit protection mechanism. It will immediately cut off the output power to prevent damage to the power supply and the connected equipment. Once the short - circuit is removed, the power supply will resume normal operation.

Physical Dimensions and Design

• Size: The power supply has a compact size of 105mm in length, 55mm in width, and 28mm in height. This compact design makes it easy to install in various electronic devices and enclosures, saving valuable space.

• Weight: It weighs approximately 0.12kg (packing weight for a single unit), which is relatively light, making it suitable for applications where weight is a consideration.

• Package Type: The open - frame design of the power supply allows for easy access to the internal components, facilitating installation and maintenance. Additionally, the open - frame design aids in heat dissipation, which is essential for maintaining the performance and reliability of the power supply, especially during continuous operation.
