The DDR-480D is a 480W DIN Rail type DC-DC converter designed for rolling stock and railway applications requiring compliance with EN50155 standards. With an input range of 67.2~154Vdc (nominal 110Vdc), it converts from standard on-board DC bus supplies to isolated 12V, 24V, or 48V outputs. Built to withstand shock and vibration per IEC61373, it operates reliably from -40~+80°C and supports current sharing for higher-power parallel configurations.

Frequently Asked Questions

Can I use the DDR-480D-48 to convert a 110V DC bus to 48V for powering PoE network infrastructure?

Yes. The DDR-480D-48 accepts 67.2-154V DC input and outputs 48V at 10A (480W). This makes it well suited for stepping down a 110V or 125V DC distribution bus to 48V for PoE switches, wireless access points, and IP cameras in industrial or commercial network deployments.

Is the DDR-480D-48 suitable for telecom rectifier systems that distribute 110V DC?

The DDR-480D-48 is designed for exactly this type of application. Its 67.2-154V DC input range accommodates 110V telecom DC distribution, and it provides a regulated 48V output at 10A. The DIN rail mount, fanless design, and 4KVdc isolation are well matched to telecom equipment rooms and outdoor cabinets.

Can the DDR-480D-48 be used in a solar or wind energy system with a high-voltage DC link?

If the DC link voltage stays within 67.2-154V, the DDR-480D-48 can convert it to a stable 48V rail at up to 10A. This is useful for powering 48V battery systems, monitoring equipment, or communication devices in off-grid renewable energy installations. The wide input range accommodates voltage fluctuations typical of renewable sources.

Can I deploy the DDR-480D-48 in a cold-climate outdoor cabinet without a heater?

The DDR-480D-48 is rated for operation from -40 to +80 degrees Celsius, so it can start and operate in extreme cold without a cabinet heater. It must still be housed in a weatherproof enclosure since it does not carry an ingress protection rating against moisture or dust.

How does the DDR-480D-48 compare to the DDR-480B-48 and DDR-480C-48?

All three are 480W, 48V/10A DC-DC converters in the same physical form factor. The difference is the input voltage range: the DDR-480B-48 accepts 16.8-33.6V, the DDR-480C-48 accepts 33.6-67.2V, and the DDR-480D-48 accepts 67.2-154V. Choose the variant that matches your DC bus voltage.
