Frequently Asked Questions
What industrial or embedded applications can the RSP-100-3.3 serve?
The RSP-100-3.3 provides 3.3V at 20A (66W) which is typical for FPGA boards, microcontroller development platforms, and embedded logic circuitry that operates on a 3.3V rail. The 85–264VAC input allows operation on any standard AC supply without modification.
Why is the RSP-100-3.3 rated at 66W rather than ~100W like other RSP-100 variants?
The RSP-100-3.3 is constrained by the maximum output current (20A) the platform can deliver at 3.3V, which results in 66W (3.3V × 20A). This is a design characteristic of the 3.3V variant within the RSP-100 platform; the 12V, 24V, and 48V variants achieve closer to 100W because their higher voltages allow less current at equivalent power.
How does the RSP-100-3.3 compare to the RSP-150-3.3?
The RSP-100-3.3 delivers 3.3V at 20A (66W) in a 179.0 × 99.0 × 30.0 mm chassis. The RSP-150-3.3 delivers 3.3V at 30A (99W) in a slightly larger 199.0 × 99.0 × 30.0 mm chassis. If the load requires more than 20A at 3.3V, the RSP-150-3.3 is the next step up within this product line.
Does the RSP-100-3.3 support operation in environments down to -30°C?
Yes. The RSP-100-3.3 is rated for -30°C to +70°C ambient, allowing reliable cold-start and sustained operation in low-temperature environments. It should be enclosed to prevent moisture and dust exposure as the unit has no IP rating.
What certifications does the RSP-100-3.3 hold?
The RSP-100-3.3 is certified under BSMI, CB, CCC, CE, EAC, TÜV, and UL, covering Taiwan, China, Europe, North America, and the Eurasian Economic Union.
