Frequently Asked Questions
What embedded or industrial loads can the RSP-100-5 power?
The RSP-100-5 delivers 5V at 20A (100W) and is suited for 5V DC logic buses, Raspberry Pi clusters, industrial microcontroller panels, USB charging banks, and relay control boards. The 85–264VAC universal input means no external transformer is required on either 110V or 230V mains.
How does the RSP-100-5 compare to the RSP-100-3.3 and RSP-100-12 at the lowest voltages?
The RSP-100-3.3 delivers 3.3V at 20A (66W), the RSP-100-5 delivers 5V at 20A (100W), and the RSP-100-12 delivers 12V at 8.5A (102W). The 3.3V variant is limited to 66W by the current ceiling; the 5V and higher-voltage variants achieve approximately 100W. All use the same 179.0 × 99.0 × 30.0 mm 1U chassis.
Is the RSP-100-5 suitable for use in rack-mounted test and measurement equipment?
Yes. At 179.0 × 99.0 × 30.0 mm (30 mm height) the RSP-100-5 fits within a 1U rack space. It delivers 100W at 5V with active PFC, which is suitable for 5V instrumentation front-ends, data acquisition modules, and other rack test equipment drawing up to 20A at 5V.
What temperature range does the RSP-100-5 support?
The RSP-100-5 operates from -30°C to +70°C ambient without derating. This covers most indoor industrial environments including cold rooms and warm server spaces. No IP rating is stated; an appropriate enclosure is required for outdoor or wet use.
What certifications cover the RSP-100-5?
The RSP-100-5 holds BSMI, CB, CCC, CE, EAC, TÜV, and UL certification. This spans Taiwan, China, Europe, North America, and the Eurasian Economic Union, supporting multi-region product qualification.
