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

The MEAN WELL PS-25 series is a line of high-performance 25-watt single-output switching power supplies. Here is a detailed introduction:

General Characteristics of MEAN WELL PS-25 series

Wide Input Voltage Range: It can accept an input voltage of 85 - 264VAC or 120 - 370VDC, enabling it to be used in a variety of power supply environments around the world.

Comprehensive Protection Functions: It is equipped with protection mechanisms against short - circuits, overloads, over - voltages, and over - temperatures. This ensures the safety of the power supply and the connected equipment in case of abnormal conditions. For example, the overload protection will be triggered when the output power exceeds 110% of the rated power.

Natural Air - Cooling Design: The power supply adopts a natural air - cooling method, which means it operates silently without the need for a cooling fan. This not only reduces noise but also enhances the reliability and reduces maintenance costs.

High - Frequency Switching Technology: With a fixed switching frequency of 67kHz, it helps to improve the efficiency of the power supply and reduce electromagnetic interference, ensuring stable operation of the power supply.

High Reliability: Each power supply unit undergoes a 100% full - load burn - in test to ensure its stability and reliability, providing users with a reliable power supply solution.

Good Electrical Characteristics: It has low leakage current (less than 0.5mA) and high - quality output voltage regulation, with an output voltage tolerance of within ±2%.

Two - Year Warranty: MEAN WELL offers a two - year warranty for this series, demonstrating its confidence in the product quality and providing users with good after - sales support.

Electrical Specifications

Output Voltage and Current: The series offers multiple output voltage options, including 5V, 12V, 15V, 24V, and 48V, with corresponding rated output currents of 5A, 2.08A, 1.67A, 1.04A, and 0.52A, respectively.

Ripple and Noise: The maximum ripple and noise values are 100mVp - p for the 5V model, 120mVp - p for the 12V and 15V models, 150mVp - p for the 24V model, and 200mVp - p for the 48V model, ensuring clean and stable output power.

Efficiency: The typical efficiency of the PS - 25 series is relatively high, ranging from 76% to 82%, which helps to reduce energy consumption and heat generation.

Environmental Specifications

Operating Temperature: The power supply can operate in a temperature range of - 10°C to 60°C. However, derating is required when the altitude is above 2000m to ensure its normal operation.

Operating Humidity: It can work in a humidity range of 20% - 90% RH non - condensing, adapting to different environmental humidity conditions.

Storage Temperature and Humidity: The storage temperature range is - 20°C to 85°C, and the storage humidity range is 10% - 95% RH.

Safety and EMC Specifications

Safety Standards: It complies with international safety standards such as IEC 60950 - 1 CB approved by TUV, ensuring the safety of users and equipment.

Withstand Voltage: The withstand voltage between the input and output is 3kVAC, between the input and FG is 1.5kVAC, and between the output and FG is 0.5kVAC. The isolation resistance between the input and output, input and FG, and output and FG is 100M ohms / 500VDC.

EMI and EMC: The EMI conduction and radiation meet the requirements of EN 55032 (CISPR 32) class B. The harmonic current complies with EN 61000 - 3 - 2 and - 3. The EMC immunity meets the requirements of EN 61000 - 4 - 2, 3, 4, 5, 6, 8, 11, light industry level.
