Frequently Asked Questions
What 48V industrial or telecom loads can the RSP-1000-48 support?
The RSP-1000-48 delivers 48V at 21A (1008W) and is appropriate for 48V DC bus applications including telecom power systems, industrial Ethernet backbone supplies, DC motor drives with 48V input, and high-power PoE switching infrastructure. The 90–264VAC input supports all standard single-phase supplies worldwide.
Can the RSP-1000-48 be used in parallel for redundancy?
Yes. The RSP-1000-48 supports active current sharing (3+1). Up to three units can operate in parallel, providing up to 63A at 48V, with a fourth unit in hot standby for N+1 redundancy. Load balancing across paralleled units is automatic.
How does the RSP-1000-48 compare to the RSP-1000-24 at the two dominant telecom voltages?
The RSP-1000-24 delivers 24V at 40A (960W) while the RSP-1000-48 delivers 48V at 21A (1008W). Both share the 295.0 × 127.0 × 41.0 mm chassis, 90–264VAC input, -20°C to +60°C range, and 5-year warranty. The 48V variant produces slightly more total wattage at half the current of the 24V model.
What environmental limits apply to the RSP-1000-48?
The RSP-1000-48 is rated from -20°C to +60°C ambient with no IP rating. It must be installed in an enclosure suited to the deployment environment. The -20°C lower limit provides adequate cold-weather start for most indoor industrial environments but may require enclosure heating in extreme cold locations.
What efficiency level does the RSP-1000-48 achieve?
The RSP-1000-48 features built-in active PFC and achieves efficiency up to 91%. At full 1008W output, input power is approximately 1108W with approximately 100W dissipated as heat, which is a favorable thermal load for a 1kW-class supply.
