The DDR-480C 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 33.6~67.2Vdc (nominal 48Vdc), 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-480C-12 to step down a 48V data center bus to 12V for high-current server components?

Yes. The DDR-480C-12 accepts 33.6-67.2V DC input, perfectly matching a standard 48V data center bus (typical 42-58V). It delivers 12V at up to 33.4A (400.8W), providing enough current for storage arrays, fan trays, or other 12V rack subsystems that draw significant power.

Is the DDR-480C-12 suitable for converting a 48V telecom DC plant to 12V for legacy radio or modem equipment?

Yes. Telecom central offices and remote sites commonly distribute 48V DC. The DDR-480C-12 converts that to an isolated 12V rail at up to 33.4A, which can power legacy 12V radio transceivers, modems, or alarm panels. The 4KVdc I/O isolation protects sensitive equipment from the main plant bus.

Can the DDR-480C-12 supply 12V power for electric vehicle charging station control electronics from a 48V DC bus?

Yes. EV charging stations often have a 48V DC internal bus for power distribution. The DDR-480C-12 converts that to 12V at up to 33.4A for control boards, displays, communication modules, and contactors. Its DIN rail mount and -40°C to +80°C rating suit outdoor charging station enclosures.

Is the DDR-480C-12 safe for use in environments with wide daily temperature swings?

Yes. It is rated for -40°C to +80°C, covering desert daytime heat as well as sub-zero overnight temperatures. The fanless design eliminates concerns about condensation-related fan failure during rapid temperature transitions. Mount it inside a sealed enclosure to prevent direct moisture contact.

How does the DDR-480C-12 compare to the DDR-480B-12 and DDR-480D-12?

All three output 12V at 33.4A (400.8W) with the same physical dimensions and fanless design. They differ only in input voltage range: DDR-480B-12 accepts 16.8-33.6V (24V bus), DDR-480C-12 accepts 33.6-67.2V (48V bus), and DDR-480D-12 accepts 67.2-154V (high-voltage DC bus). Choose based on your source DC voltage.
