## Long description

The MEAN WELL RS-25 25W Metallic is a compact industrial power supply unit designed for stable DC output from universal AC mains. It accepts a wide AC input range (115–230VAC, 47–63Hz), features low no-load power consumption and is built for long service life with an MTBF of 309700 hours. The unit has a metallic case, a 25 W output rating and compact dimensions (51 × 78 × 28 mm), making it suitable for space-limited electrical installations.
Advantages
The RS-25 provides full-range universal AC input with high efficiency and low standby consumption (\<0.5 W). It includes multiple protections — short circuit, overload and over-voltage — and an LED power-on indicator. The supply is validated by 100% full-load burn-in testing, can withstand 300 VAC surge for 5 seconds, endures 5G vibration testing and operates reliably at high ambient temperatures up to 70 °C. A 3-year warranty covers manufacturing defects.
Suitable for
 Industrial control panels and automation equipment
 Embedded systems and compact electronic devices
 Lighting drivers and small LED installations
 Powering sensors, relays and communication modules

How to use
Mount the MEAN WELL RS-25 in a location with adequate ventilation to allow free air convection cooling. Connect the AC input to the rated mains voltage (115–230 VAC) following local electrical codes and ensure correct polarity on the DC output terminals. Verify the LED indicator for power-on status and confirm output voltage within the specified tolerance. Do not exceed the 25 W output rating and avoid placing the unit near heat sources or enclosed spaces that prevent airflow.
Usage recommendations
For reliable long-term operation, install the RS-25 in a ventilated enclosure, protect the input with appropriate fusing or surge protection, and observe the specified ambient temperature limits. Perform periodic inspections for loose connections and ensure cooling clearance around the unit.
