Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 0% to 100% rated load.
- 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 “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 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.
