Test conditions and notes6

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. 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 )
5. Strongly recommended that external output capacitance should not exceed 5000uF.(Only for: RSP-100-3.3/-5/-7.5)
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).

FAQ

What 48V applications can the RSP-100-48 support?

The RSP-100-48 delivers 48V at 2.1A (100.8W) and is appropriate for low-power 48V DC bus applications such as PoE switch auxiliary rails, industrial Ethernet backbone power, motor drive logic supplies, and distributed 48V bus segments in automation cabinets. The 85–264VAC input makes it compatible with all standard AC supplies.

How does the RSP-100-48 compare to the RSP-100-24 and RSP-100-27?

The RSP-100-24 outputs 24V at 4.2A (100.8W), the RSP-100-27 outputs 27V at 3.8A (102.6W), and the RSP-100-48 outputs 48V at 2.1A (100.8W). All share the same 179.0 × 99.0 × 30.0 mm chassis, 85–264VAC input, and -30°C to +70°C operating range. Higher voltage variants deliver proportionally lower current at similar wattage.

Is the RSP-100-48 appropriate for telecom equipment requiring a 48V supply?

Yes. 48V DC is a standard bus in telecom infrastructure. At 100.8W the RSP-100-48 is suited for low-draw 48V telecom accessories, optical network unit (ONU) power, and small PBX systems drawing up to 2.1A.

What is the enclosure requirement for the RSP-100-48 in a dusty industrial environment?

The RSP-100-48 carries no IP ingress rating, so it must be mounted inside a sealed or filtered enclosure when used in dusty or wet industrial environments. It is rated for -30°C to +70°C operation and can handle the temperature demands of most factory installations when properly enclosed.

What are all RSP-100 series voltage options?

The RSP-100 series covers the following voltage options: RSP-100-3.3 (66W/3.3V/20A), RSP-100-5 (100W/5V/20A), RSP-100-7.5 (101.25W/7.5V/13.5A), RSP-100-12 (102W/12V/8.5A), RSP-100-13.5 (101.25W/13.5V/7.5A), RSP-100-15 (100.5W/15V/6.7A), RSP-100-24 (100.8W/24V/4.2A), RSP-100-27 (102.6W/27V/3.8A), RSP-100-48 (100.8W/48V/2.1A). All variants use the same 179.0 × 99.0 × 30.0 mm chassis and 85–264VAC input.
