Description
Mean Well RSP-3000-48 3000W Switching Power Supply 200-240VAC 20A 48VDC 62.5A
The Mean Well RSP-3000-48 is a 3000-watt single-output enclosed AC/DC switching power supply delivering 48VDC at 62.5A. It is designed for demanding industrial applications that require high power density, programmable output, and the ability to parallel multiple units for increased capacity. Built-in active PFC and high efficiency (up to 91.5%) make it well suited for continuous-duty industrial environments.

Applications
The Mean Well RSP-3000 series is used in industrial automation, battery charging systems, telecommunications equipment, LED lighting infrastructure, and high-power DC bus applications. The 48VDC output is a standard bus voltage in telecom and datacom installations, and the RSP-3000-48 is commonly used in rectifier and charging systems where a stable, high-current 48V rail is required. The parallel current-sharing capability (up to three units, 9000W total) allows the supply to scale with load requirements or provide N+1 redundancy — a feature valued in always-on industrial and telecom environments. The programmable output voltage range (20–110% of rated) adds flexibility for applications requiring a tunable DC rail.
This Mean Well RSP-3000-48 3000W switching power supply has been tested and is in good working condition. We have multiple units of this model in stock, and the unit shipped may differ slightly from the one photographed but will be functionally equivalent. One important operating note: without the red loop wire installed on the CN1 connector's black port, the unit defaults to remote control mode. All wires and connector parts shown in the photos are included so the unit can be operated as shown. The unit shows normal wear consistent with prior use; overall cosmetic condition is very good. Please view our photo set and contact us if you have any questions.
