MEANWELL PS-25-13.5 25W single-output switching power supplies

Here is an English introduction to the MEANWELL PS-25-13.5 25W single - output switching power supply:

The MEANWELL PS-25-13.5 is a high - performance single - output switching power supply designed to provide stable and reliable power for various electronic devices.

Electrical Characteristics

• Input Voltage Range: It accepts a wide input voltage range of 90 - 264VAC, enabling it to be used in different power grid environments. This wide range ensures that the power supply can operate normally even when the input voltage fluctuates.

• Output Voltage and Current: The power supply offers a precise 13.5VDC output voltage. With a maximum output current of 1.85A, it can deliver a rated power of 25W. The output has low ripple and noise, typically within 100mVp - p, ensuring clean power for the connected equipment. The voltage regulation is excellent, with both line regulation and load regulation within ±0.5%, which means the output voltage remains stable under different input and load conditions.

Protection Functions




• Overload Protection: The power supply is equipped with overload protection. When the output power exceeds the rated value, usually in the range of 28 - 35W, the protection circuit will be activated. It adopts the hiccup mode, which means that the power supply will automatically shut down when an overload occurs and try to recover once the overload condition is removed. This protects the power supply and the connected devices from damage.

• Over - Voltage Protection: The over - voltage protection is set to operate when the output voltage reaches 15 - 18V. If the output voltage exceeds this range, the power supply will enter a protection state and then recover automatically after the fault is eliminated. This feature safeguards the connected devices from the risk of over - voltage damage.

• Short - Circuit Protection: In the event of a short - circuit at the output, the power supply can protect itself and the connected equipment. The short - circuit protection function will immediately cut off the output power and resume normal operation once the short - circuit is resolved.
