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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltages. Please check the derating curve for more details.
  5. 5. Touch current was measured from primary input to DC output.
  6. 6. 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).
  7. 7. The power supply is considered a component which will be installed into a final equipment. 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 )

FAQ

Can I use the RPS-65-48 for 48V industrial control or telecom equipment?

Yes, if the equipment requires a constant 48V output and draws no more than 1.36A or 65.3W. That makes it suitable for compact 48V control, communications, or embedded systems within those electrical limits.

Is the RPS-65-48 suitable for medical or embedded devices that operate on 48V DC?

It can be used for 48V medical or embedded electronics that remain within the 1.36A and 65.3W output rating. This model is medical safety approved and is specified with extremely low leakage current.

Can this model power a 48V network, monitoring, or automation device from AC mains?

Yes, provided the load is designed for 48V constant-voltage input and stays at or below 1.36A. The unit accepts 80-264VAC input and converts it to regulated 48V DC output.

Is the RPS-65-48 useful where a small 48V AC-DC supply is needed inside equipment?

Yes, its 76.2 x 50.8 x 24.0 mm size and 0.11 kg weight make it suitable for compact equipment layouts. It is intended for applications needing 48V output without moving up to a larger higher-power model.

Can the RPS-65-48 be used outside or in unsealed industrial environments?

This product does not include a stated IP rating, so it is better used indoors or inside a protected enclosure. Its specified operating temperature range is -30°C to +70°C.

How does the RPS-65-48 compare with other 48V models in the RPS family?

The listed 48V models are RPS-30-48 at 30W and 0.62A, RPS-45-48 at 45.1W and 0.94A, RPS-60-48 at 60W and 1.25A, RPS-65-48 at 65.3W and 1.36A, RPS-75-48 at 76.8W and 1.6A, RPS-120-48 and RPS-120-48-C at 84W and 2.5A, RPS-120S-48 at 120W and 2.5A, RPS-160-48 at 113.4W and 2.3A, RPS-200-48 and RPS-200-48-C at 144W and 3A, RPS-300-48 and RPS-300-48-C at 200.2W and 4.17A, RPS-400-48 and its -C, -SF, and -TF versions at 254.4W and 5.3A, and RPS-500-48 and its -C, -SF, and -TF versions at 321.6W 6.7A, 312W 6.5A, and 499.2W 10.4A. The RPS-65-48 is one of the lower-power 48V choices in that lineup.
