What systems require a 3.3V, high-current supply like the RSP-320-3.3?

The RSP-320-3.3 provides 3.3V at 60A (198W), a rail commonly required for FPGA I/O banks, DDR memory subsystems, and logic-level power on embedded computing boards. Its 1U profile enables integration into compact rack or panel enclosures.

What is the operating temperature range of the RSP-320-3.3?

The RSP-320-3.3 operates from -30°C to +70°C ambient. It is designed for indoor enclosed use and holds UL, CE, TÜV, CB, CCC, BSMI, and EAC certifications.

How does the RSP-320-3.3 compare to the RSP-320-2.5 and RSP-320-4?

The RSP-320-2.5 delivers 2.5V at 60A for 150W, the RSP-320-3.3 delivers 3.3V at 60A for 198W, and the RSP-320-4 delivers 4V at 60A for 240W. All three share the same chassis and 88-264VAC input. The RSP-320-3.3 offers the middle power level in this low-voltage group.

What is the actual rated power output of the RSP-320-3.3?

The RSP-320-3.3 is rated at 198W (3.3V × 60A). This is lower than the model-name designation of 320W because the low output voltage limits total power at the rated current.
