Mean Well

Mean Well RS-25-48 48V 0.57A 27.36W Power Supply

SKU CH-KAT4-MW1EK

A compact 27.36 W switching supply delivering 48 V at 0.57 A, rated for 70 °C operation and 300 VAC surge tolerance

  • Product typeAT
  • Delivers stable 48 V DC at 0.57 A for sensitive electronics
  • 36 W output handles modest industrial loads efficiently
  • Withstands 300 VAC surge input for 5 seconds in harsh environments
  • Operates reliably up to 70 °C ambient temperature
  • Built with 105 °C rated electrolytic capacitors for extended service life

Fixed 48V Output

The Mean Well RS-25-48 is a new single-output switching power supply that delivers 48V at 0.57A for a total of 27.36W. It is built with 105°C electrolytic capacitors and rated to withstand 5G vibration and a 70°C operating temperature. The unit also tolerates a 300VAC surge input for five seconds, making it suited for harsh industrial environments.

Industrial Equipment Builders

This supply suits engineers and technicians who need a compact, regulated 48V source for automation, instrumentation or fixed-voltage DC systems. Buyers who require adjustable output, multiple rails or higher current capacity should look at other models.

48V 0.57A Single Rail

The defining specification is the fixed 48V, 0.57A single rail that provides exactly 27.36W. If your application demands this precise voltage and current combination, the RS-25-48 matches it; otherwise a different rating is needed.

Questions about this item

What does the 27.36W rating mean for a device that needs 48V power?

It means the supply can deliver up to 0.57A at 48V, so any connected load must stay at or below that current draw.

What input voltage range does the RS-25-48 accept and what surge can it handle?

The unit tolerates a 300VAC surge for five seconds, protecting it from brief mains spikes in harsh environments.

What mounting space and vibration rating should I plan for?

The supply is rated for 5G vibration resistance and uses 105°C capacitors, so it fits in rugged enclosures that see heavy mechanical stress.
