RSP-200
SMUN
The RSP-200 Series is a highly reliable, 200W single-output enclosed power supply designed with an active Power Factor Correction (PFC) function. Engineered to meet the strict operational demands of telecom systems, industrial automation equipment, and medical devices, this series delivers stable and efficient power conversion. Featuring a low-profile 30mm design, it is an excellent choice for installations where space is limited, such as 1U rackmount applications. The series provides a versatile range of output voltages from 12V to 48V, notably including a specialized 27.3V model that is frequently required for specific telecommunication and DC backup systems. By integrating advanced circuitry, the RSP-200 series helps procurement professionals and engineers reduce energy consumption while ensuring long-term operational stability in critical project environments.
The following table outlines the detailed electrical specifications for each voltage model. Selecting the correct output voltage and rated current is crucial for ensuring compatibility and optimal performance with your specific equipment.

Please review the following testing conditions and operational guidelines to ensure accurate performance evaluation and safe deployment within your systems.
All unspecified parameters are measured at 230VAC input, full load, 25°C unless noted.
Ripple noise measurements use a bandwidth of 20MHz with 12-inch twisted-pair wires and parallel 0.1μF + 47μF capacitors.
Low-input voltage operation requires derating (refer to derating curves).
EMC testing uses a 1mm-thick steel plate (360×360mm).
When selecting between the RSP-200 and RSP-320 series, consider the following primary differences to accurately match your project's power capacity, thermal management, and weight requirements.
Power Rating: 200W vs. 320W.
Output Voltages: Includes 27.3V (common in telecom/dc systems).
Efficiency: Slightly lower (up to 90%) compared to the 320W series.
Cooling: Free air convection vs. forced air cooling in the 320W series.
Package Weight: Lighter (0.72kg vs. 0.9kg for 320W).
