Frequently Asked Questions
What is the RSP-320-48 well-suited for in a 48V system?
The RSP-320-48 delivers 48V at 6.7A (320W), appropriate for powering PoE switches, small telecom equipment, and 48V DC bus subsystems in compact enclosures. Its 1U low-profile form factor (215.0 × 115.0 × 30.0 mm) supports tight rack or panel installations.
Does the RSP-320-48 operate in cold environments?
The RSP-320-48 is rated for -30°C to +70°C ambient, suitable for cold-climate indoor enclosures. It carries BSMI, CB, CCC, CE, EAC, TÜV, and UL certifications and is not rated for outdoor use.
How does the RSP-320-48 compare to other RSP-320 high-voltage variants?
Within the RSP-320 series, the RSP-320-36 provides 320W at 8.9A and the RSP-320-48 provides 320W at 6.7A, both sharing the same 215.0 × 115.0 × 30.0 mm chassis and 88-264VAC input. The RSP-320-48 is the highest-voltage and lowest-current option in the RSP-320 line.
Does the RSP-320-48 accept universal AC input?
Yes. The RSP-320-48 accepts 88-264VAC, covering worldwide single-phase AC systems without manual switching. It includes built-in active PFC.
