Overview
What it is
The MEAN WELL RSD-500D-12 is a 420 W enclosed DC-DC converter from the RSD-500 series (500 W Enclosed Type Reliable Railway DC-DC Converter). It provides a 12 V DC output with up to 35 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: 12 V, 35 A rated current, 420 W rated power.
- Output voltage adjustable over 12 to 14 V.
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.
