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. 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSP-150-3.3/-5/-7.5/-12)
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

What industrial applications require the 27V output of the RSP-150-27?

The RSP-150-27 delivers 27V at 5.6A (151.2W) and is suited for loads requiring a 27V DC bus, such as 24V lead-acid battery float chargers, select servo drives, and industrial systems that specify 27V as a nominal rail. The 85–264VAC input supports all standard AC supplies.

Does the RSP-150-27 have an operating temperature range suitable for warm environments?

The RSP-150-27 is rated from -30°C to +70°C, with output derating at higher temperatures per the datasheet derating curve, so check the curve for your load at warm ambients. No IP rating is specified, so enclosure protection is required for dusty or wet locations.

What certifications does the RSP-150-27 hold?

The RSP-150-27 is approved to UL62368-1, TÜV BS EN/EN62368-1, BS EN/EN61558-1 and BS EN/EN61558-2-16, EAC TP TC 004, CCC GB4943.1, BSMI CNS15598-1, AS/NZS 62368.1 and IS13252(Part1)/IEC60950-1, covering North America, Europe, EAC, China, Taiwan, Australia/NZ and India.

What are all voltage variants available in the RSP-150 series?

The RSP-150 series voltage options are: RSP-150-3.3 (99W/3.3V/30A), RSP-150-5 (150W/5V/30A), RSP-150-7.5 (150W/7.5V/20A), RSP-150-12 (150W/12V/12.5A), RSP-150-13.5 (151.2W/13.5V/11.2A), RSP-150-15 (150W/15V/10A), RSP-150-24 (151.2W/24V/6.3A), RSP-150-27 (151.2W/27V/5.6A), RSP-150-48 (153.6W/48V/3.2A). All share the 199.0 × 99.0 × 30.0 mm chassis and 85–264VAC input.
