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 loads is the RSP-100-27 intended for at 27V?

The RSP-100-27 delivers 27V at 3.8A (102.6W) and is suited for loads requiring a 27V DC bus, such as industrial pneumatic valve drivers, 24V lead-acid battery float chargers that need a slightly elevated supply, and certain specialty telecommunications equipment. The 85–264VAC input provides broad AC compatibility.

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

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 three use the same chassis (179.0 × 99.0 × 30.0 mm) and 85–264VAC input. The RSP-100-27 is the midpoint between 24V and 48V in this series.

Can the RSP-100-27 be used in telecom or datacom cabinets?

The RSP-100-27 is rated for -30°C to +70°C operation (with derating at higher temperatures) and is approved to UL62368-1, TÜV BS EN/EN62368-1, CCC, BSMI, EAC and BIS. Its 27V output and compact 179 × 99 × 30 mm size make it compatible with telecom auxiliary circuits and datacom control boards that require a regulated 27V rail. The 3.8A output limits total load to 102.6W.

Is the RSP-100-27 rated for cold-climate operation?

Yes. The operating temperature floor of -30°C allows the RSP-100-27 to run in sub-zero ambient conditions, such as unheated indoor plant rooms and cold-storage facilities. No IP ingress rating is specified, so it must be installed in an enclosure that keeps it dry (20–90% RH non-condensing).

What are all voltage options available in the RSP-100 family?

The RSP-100 series offers output voltages from 3.3V to 48V across a single platform: 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 models accept 85–264VAC input and share the 179.0 × 99.0 × 30.0 mm chassis.
