MEAN WELL DDR-480C-24 DC/DC-converter 24V 20A 480W DIN-rail

Industrial and railway systems often face unstable DC input voltages that can damage sensitive electronics or cause downtime. The MEAN WELL DDR-480C-24 DC/DC converter solves this by converting a wide 150–420 VDC input into a stable, isolated 24 VDC output, delivering up to 480 W of clean power for demanding applications.

Who is it for

This converter is ideal for engineers and system integrators working with DC-powered industrial automation, transportation, or renewable energy systems where a reliable 24 VDC bus is required from higher-voltage DC sources.
