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 embedded systems or logic circuits can the RSP-150-3.3 power?

The RSP-150-3.3 provides 3.3V at 30A (99W) and is suited for 3.3V logic buses in FPGA systems, microprocessor boards, embedded controller racks, and digital signal processing platforms. At 30A output current it can serve larger multi-board configurations. The 85–264VAC universal input is compatible with standard AC mains worldwide.

Why does the RSP-150-3.3 deliver 99W rather than 150W?

The 3.3V model is rated for a maximum output current of 30A (current range 0–30A), so its rated power is 3.3V × 30A = 99W. The 150W series rating applies to the 5V, 7.5V, 12V and 15V models; the 13.5V, 24V and 27V models are rated 151.2W and the 48V model 153.6W.

What is the operating temperature range of the RSP-150-3.3?

The RSP-150-3.3 operates from -30°C to +70°C ambient, with output derating at higher temperatures per the datasheet derating curve, and 20–90% RH non-condensing humidity. The datasheet specifies no IP ingress rating, so for harsh environments the unit should be installed inside a protective enclosure. The low-temperature capability down to -30°C supports cold-start in industrial cold-storage applications.

What certifications does the RSP-150-3.3 carry?

The RSP-150-3.3 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 (Australia and New Zealand) and IS13252(Part1)/IEC60950-1.
