Frequently Asked Questions

What is a typical application for a 4V, 90A power supply?

The RSP-500-4 delivers 4V at 90A (360W), used for powering low-voltage bus converters, telecom processing board power rails, and certain embedded computing subsystems that specify a regulated 4V source with high current capacity.

What is the cold-temperature limit of the RSP-500-4?

The RSP-500-4 operates down to -30°C ambient, with an upper limit of +70°C. It carries BSMI, CB, CCC, CE, EAC, c_rcm, TÜV, and UL certifications and is rated for indoor enclosed use.

How does the RSP-500-4 compare to the RSP-500-3.3 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. Current output is identical across the three; power scales with voltage.

What is the actual rated power of the RSP-500-4?

The RSP-500-4 is rated at 360W (4V × 90A). It includes built-in active PFC and weighs 1.3 kg. A 3-year warranty is included.
