## Long description

The MEAN WELL RS-25 is a compact metallic power supply unit delivering 25.2 W of output power. It accepts a universal AC input (115–230 V, 47–63 Hz) and is designed for continuous operation with a high MTBF of 309,700 hours. The unit features low no-load consumption, an LED power indicator and a robust mechanical design withstanding vibration and surge inputs.
Advantages
The RS-25 provides wide AC input range with surge immunity up to 300 VAC for 5 seconds, built-in protections against short circuit, overload and over voltage, and cooling by free air convection that removes the need for fans. It undergoes 100% full-load burn-in testing, supports operation up to 70°C, offers high efficiency and low standby power (\<0.5 W), and comes with a 3-year warranty.
Suitable for
 Embedded systems and industrial control equipment
 Communication devices and network appliances
 Small automation modules and sensors
 Applications requiring compact, fanless power supplies
