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-35-48 for 48V telecom or industrial communications equipment?

Yes, if the equipment is designed for a constant 48V DC input and draws no more than 35W and 0.8A. That makes it relevant for lighter-duty telecom or industrial communications hardware built around a 48V DC bus.

Is the RS-35-48 suitable for 48V control devices in automation systems?

It can be used for small 48V control devices or subsystems when the total demand stays within 0.8A at 48V. The supply is constant voltage, so it should only be used with equipment intended for a regulated 48V DC source.

Can this power supply support compact embedded or IT hardware that runs on 48V DC?

It is suitable for compact embedded or IT hardware that accepts 48V DC input and remains within the 35W output limit. Its 99.0 × 82.0 × 36.0 mm size is also useful where mounting space is constrained.

Is the RS-35-48 rated for outdoor use?

The provided specs show an operating temperature range of -25°C to +70°C, but no IP rating is listed. Without an IP rating, it is better considered for indoor cabinets or other protected enclosures instead of exposed outdoor locations.

How does RS-35-48 compare with the other 35W RS models?

The 35W RS lineup includes RS-35-3.3 at 3.3V and 7A, RS-35-5 at 5V and 7A, RS-35-12 at 12V and 3A, RS-35-15 at 15V and 2.4A, RS-35-24 at 24V and 1.5A, and RS-35-48 at 48V and 0.8A. RS-35-48 is the highest-voltage version in that 35W group and therefore carries the lowest current rating.
