MEANWELL PS-25-15 25W single-output switching power supplies

Here is an English introduction to the MEANWELL PS - 25 - 15 25W single - output switching power supply:

The MEANWELL PS - 25 - 15 is a high - quality, reliable single - output switching power supply designed to meet a variety of power needs.

Electrical Specifications

• Input Voltage: It supports a wide input voltage range of 90 - 264VAC, allowing it to be used in different electrical environments. This wide range ensures stable operation even with fluctuations in the input power.

• Output Characteristics: The power supply provides a stable 15VDC output voltage with a maximum output current of 1.67A, capable of delivering a rated power of 25W. It has low ripple and noise, typically around 100mVp - p, ensuring clean and stable power for the connected devices. The voltage regulation is within ±0.5%, both for line regulation and load regulation, which means the output voltage remains highly stable under different input and load conditions.




Protection Features




• Overload Protection: In case of overload, the power supply is protected. The overload protection range is 28 - 35W. It uses the hiccup mode, which means that when an overload occurs, the power supply will automatically shut down and then attempt to recover once the overload condition is removed. This helps prevent damage to the power supply and the connected equipment.

• Over - Voltage Protection: The over - voltage protection is set to operate in the range of 17 - 21V. If the output voltage exceeds this range, the power supply will enter a protection mode and then recover automatically after the fault is cleared. This feature safeguards the connected devices from potential damage due to over - voltage.

• Short - Circuit Protection: Equipped with short - circuit protection, the power supply can handle short - circuit situations without being damaged. When a short - circuit occurs, the power supply will stop delivering power and resume normal operation once the short - circuit is removed.

Physical Attributes




• Dimensions: With dimensions of 105mm in length, 55mm in width, and 28mm in height, it has a compact design that allows for easy installation in various equipment and enclosures.

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

• Package Type: The open - frame design of the power supply provides easy access to the internal components for installation and maintenance. It also allows for better heat dissipation, which is beneficial for the overall performance and reliability of the power supply.

Environmental Considerations




• Operating Temperature: The power supply can operate in a temperature range of - 10 - 60°C. However, it is recommended to refer to the derating curve for specific operating conditions to ensure optimal performance and reliability. This wide temperature range makes it suitable for use in different environments, from relatively cold to warm conditions.

• Humidity: It can work in an environment with a humidity level of 20 - 90% RH, non - condensing. This ensures that the power supply can operate reliably in various humid conditions without the risk of moisture - related damage.

• Storage Conditions: For storage, the recommended temperature range is - 20 - 85°C, and the humidity range is 10 - 95% RH. These conditions ensure the long - term storage stability of the power supply.
