Test conditions and notes8

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. 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. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
8. 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-100-48 for a 48V industrial control or automation panel?

Yes, it is a constant-voltage 48V supply with up to 2.3A output and 110.4W capacity, which fits equipment designed for a 48V DC rail. The wide 88-264VAC input also suits panels used in different AC power environments.

Is the RS-100-48 suitable for 48V telecom or network equipment?

It can be suitable for 48V DC equipment that stays within 2.3A and 110.4W. This model is a constant-voltage power supply, so it fits loads that specifically require a 48V regulated output.

Can this power supply run a 48V embedded system or test fixture?

Yes, if the fixture or embedded system needs a stable 48V output and draws no more than 2.3A. Its compact 159.0 × 97.0 × 38.0 mm size and 0.6 kg weight also help where enclosure space is limited.

How does the RS-100-48 compare with other 48V models in the RS series?

The RS-100-48 provides 110.4W at 2.3A. Other 48V models in the RS series include the RS-15-48 (15W), RS-25-48 (27.36W), RS-35-48 (35W), RS-50-48 (52.8W), RS-75-48 (76.8W), and RS-150-48 (158.4W). The main difference is available output current and power at the same 48V nominal output.

Is the RS-100-48 meant for indoor or outdoor use?

The operating temperature range is -25°C to +70°C, and the unit is specified to withstand 5G vibration. No IP rating is listed in the provided specs, so these specs support temperature tolerance but do not establish outdoor or weather-exposed use.
