Overview

What it is

The MEAN WELL RSDH-300-48 is a 300 W enclosed DC-DC converter from the RSDH-300 series (300 W High Reliable 250 to 1500 V DC Ultra Wide Input DC-DC Converter). It provides a 48 V DC output with up to 6.25 A of rated current.

What it is used for

Enclosed DC-DC converters run equipment from a DC source such as a battery bank or a different DC rail.

Key Specifications

  • Input range: 250 to 1500 V DC.
  • Output: 48 V, 6.25 A rated current, 300 W rated power.
  • Output voltage adjustable over 48 to 58 V.
  • Typical efficiency: 91%.
  • Operating temperature: -40 to +80 °C (see derating curve in datasheet).
  • Dimensions: 237 x 100 x 41 mm (L x W x H).

Buying considerations

Choose a rated current with headroom above the total load of the connected devices, and check the derating curve in the datasheet if the supply will run hot or at low input voltage. Other output voltages and power ratings in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component to be installed inside final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring, safety and EMC details are in the official datasheet linked below.
