Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1ΞΌF & 47ΞΌF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to β€œEMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  7. 7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the RS-25-48 for a small 48V industrial control or communications device?

Yes, if the equipment requires a 48V constant voltage input and draws no more than 0.57A or 27.36W. That makes it suitable for lower-power 48V control and communications electronics within that load range.

Is the RS-25-48 suitable for compact 48V embedded or networking equipment?

It can be used for compact 48V equipment because the housing is 78.0 x 51.0 x 28.0 mm and the weight is 0.2 kg. Its output rating is 48V constant voltage up to 0.57A.

Can this power supply support a low-power 48V automation subsystem?

It can support a low-power 48V subsystem as long as the connected load does not exceed 0.57A and 27.36W. The wide 88-264VAC input also supports deployment where AC input range flexibility is needed.

Would the RS-25-48 be a match for a 48V device in a vibration-prone machine enclosure?

The feature list states that it withstands 5G vibration and can operate up to 70 degrees C. For lower-power 48V electronics in machine or control enclosures, those stated limits are relevant if the electrical load stays within 0.57A.

Is the RS-25-48 intended for outdoor use?

The provided data lists an operating temperature range of -20 degrees C to +70 degrees C, but no IP rating is given. Based on the stated specs, temperature capability is defined, while outdoor weather exposure or sealed-enclosure performance is not.

How does the RS-25-48 compare with the other RS-25 voltage options?

The RS-25 family includes RS-25-3.3 at 19.8W, 3.3V, 6A; RS-25-5 at 25W, 5V, 5A; RS-25-12 at 25.2W, 12V, 2.1A; RS-25-15 at 25.5W, 15V, 1.7A; RS-25-24 at 26.4W, 24V, 1.1A; and RS-25-48 at 27.36W, 48V, 0.57A. This is the highest-voltage RS-25 option in the listed group and correspondingly has the lowest output current.
