Frequently Asked Questions
What equipment uses a 3.3V, high-current rail that the RSP-500-3.3 can supply?
The RSP-500-3.3 provides 3.3V at 90A (297W), suitable for powering DRAM subsystems, FPGA I/O logic rails, and logic-level loads in industrial computing boards that require a high-current 3.3V source.
What temperature range does the RSP-500-3.3 operate in?
The RSP-500-3.3 is rated for -30°C to +70°C ambient operation. It carries BSMI, CB, CCC, CE, EAC, c_rcm, TÜV, and UL certifications and is designed for indoor enclosed use.
How does the RSP-500-3.3 compare to the RSP-500-4 and RSP-500-5?
All three share the 230.0 × 127.0 × 40.5 mm chassis and 85-264VAC input. The RSP-500-3.3 provides 297W at 90A, the RSP-500-4 provides 360W at 90A, and the RSP-500-5 provides 450W at 90A. All three run at 90A; total power increases as output voltage rises.
What is the actual rated output power of the RSP-500-3.3?
The RSP-500-3.3 is rated at 297W (3.3V × 90A). The low output voltage limits total power below the RSP-500 series nameplate. It weighs 1.3 kg and includes a 3-year warranty.
