Frequently Asked Questions
What applications is a 3.3V, 15A compact supply like the RSP-75-3.3 suited for?
The RSP-75-3.3 provides 3.3V at 15A (49.5W), suitable for powering logic-level subsystems on embedded boards, FPGA I/O banks, and small industrial controllers where a regulated 3.3V rail is required in a confined space. Its 159.0 × 97.0 × 30.0 mm chassis enables use in tight enclosures.
What is the operating temperature range of the RSP-75-3.3?
The RSP-75-3.3 operates from -25°C to +70°C ambient. It carries BSMI, CB, CCC, CE, EAC, TÜV, and UL certifications and is rated for indoor enclosed use.
How does the RSP-75-3.3 compare to the RSP-75-5 and RSP-75-7.5?
All three use the same 159.0 × 97.0 × 30.0 mm chassis and 85-264VAC input. The RSP-75-3.3 provides 49.5W at 15A, the RSP-75-5 provides 75W at 15A, and the RSP-75-7.5 provides 75W at 10A. The RSP-75-3.3 produces the lowest total power of the group because the low output voltage limits wattage at the rated 15A.
What is the actual rated power of the RSP-75-3.3?
The RSP-75-3.3 is rated at 49.5W (3.3V × 15A). Despite the RSP-75 series designation, the low output voltage constrains total output power. It weighs 0.44 kg and includes a 3-year warranty.
