Overview

What it is

The MEAN WELL RSD-300E-48 is a 302.4 W enclosed DC-DC converter from the RSD-300 series (300 W Railway Single Output DC-DC Converter). It provides a 48 V DC output with up to 6.3 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. MEAN WELL designs this series for railway applications; see the datasheet for the railway standards it meets.

Key Specifications

Output: 48 V, 6.3 A rated current, 302.4 W rated power.
Typical efficiency: 91%.
Operating temperature: -40 to +55 °C (no derating); +70 °C @ 60% load by free air convection; +70 °C no derating with external base plate, TX class compliance.
Dimensions: 216 x 96.5 x 40 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.
