Mean Well DDR-30L-24 DC-DC Converter - 30W - 18~75V in 24V out

Yes. The DDR-30L-24 accepts 18-75V DC input, covering the full range of a 48V telecom bus (typically 36-72V). It delivers 24V at up to 1.25A (30W) with 4KVdc I/O isolation, making it well suited for small network switches, media converters, and other 24V edge devices mounted in telecom racks or cabinets.

Yes, provided the total load stays within 30W. At 24V and 1.25A, it can drive a few solenoid valves or small pneumatic actuators typical in process automation. Its DIN rail form factor and slim 35mm width integrate neatly alongside other automation components in standard control panels.

Yes. The 18-75V input range accommodates a 72V nominal DC bus commonly used in some building automation and solar array configurations. The converter delivers isolated 24V at up to 1.25A, which is enough for BACnet controllers, room sensors, and similar low-power 24V building automation devices.

No. The DDR-30L-24 uses a fanless convection-cooled design with no moving parts, so it operates silently in sealed enclosures. It is rated for -40°C to +85°C ambient temperature. In tightly sealed cabinets where ambient temperature may rise significantly, ensure adequate thermal headroom to stay within the rated range.

The DDR-L series with 18-75V input offers 24V output at multiple power levels: DDR-15L-24 (15W, 0.63A), DDR-30L-24 (30W, 1.25A), and DDR-60L-24 (60W, 2.5A). For even higher loads, the DDR-120 through DDR-480 families offer up to 480W at 24V, though they use different input voltage sub-ranges depending on the letter suffix (A, B, C, or D).
