The DDR-30G is a 30W DIN Rail type DC-DC converter with a 35mm (2SU) profile, designed for industrial control cabinets and distributed power systems. A 4:1 wide input voltage range of 9~36Vdc supports a broad range of DC supply sources, while reinforced 4KVdc I/O isolation ensures noise-free power conversion. Cooled entirely by free air convection with no minimum load requirement, it operates reliably from -40~+85°C.

Frequently Asked Questions

Can I use the DDR-30G-24 to step up a 12V battery source to 24V for small automation loads?

Yes. The DDR-30G-24 accepts 9-36V DC input, so a 12V battery (typically 10.5-14.4V under load/charge) is within range. It outputs 24V at up to 1.25A (30W), which can power small 24V solenoid valves, DIN rail relays, or compact PLCs in field-mounted enclosures.

Is the DDR-30G-24 suitable for powering 24V building automation sensors from a 24V DC bus?

Yes, though note the 9-36V input range means a nominal 24V bus works only if the bus voltage stays above 9V under all conditions. For a stable 24V bus, the DDR-30G-24 converts it to a clean, isolated 24V output at up to 1.25A (30W), which is useful when you need galvanic isolation between the bus and sensitive sensors.

Can the DDR-30G-24 provide an isolated 24V supply for communication modules in a remote cabinet?

Yes. The 4KVdc I/O isolation separates the input and output circuits, preventing ground loops and noise from the source bus from reaching sensitive RS-485, Modbus, or Ethernet communication modules. At 30W it can power several low-power communication devices simultaneously.

Will the DDR-30G-24 survive in an unheated roadside traffic control cabinet?

Yes. With a -40°C to +85°C operating range and fully fanless design, the DDR-30G-24 handles the seasonal temperature extremes found in roadside cabinets. Its compact size (90.0 x 54.5 x 35.0 mm) and light weight (0.12 kg) are well suited for space-limited traffic control enclosures.

Can I use the DDR-30G-24 in a solar-powered remote monitoring station?

Yes. If the solar battery voltage stays between 9V and 36V, the DDR-30G-24 produces a regulated 24V at up to 1.25A. This suits small remote stations powering cameras, weather sensors, or cellular modems where total load is under 30W.
