Mean Well DDR-30L-5 DC-DC Converter - 30W - 18~75V in 5V out
The DDR-30L is a 30W DIN Rail type DC-DC converter with a 35mm (2SU) profile, suited for systems powered from 24V or 48V DC buses. A 4:1 wide input voltage range of 18~75Vdc covers nominal 24V and 48V supplies, and reinforced 4KVdc I/O isolation ensures clean, noise-resistant power conversion. Cooled by free air convection with no minimum load requirement, it operates across a -40~+85°C working range.

Frequently Asked Questions
Can I use the DDR-30L-5 to supply 5V logic power to microcontroller-based monitoring boards in an industrial panel?
Yes. The DDR-30L-5 delivers 5V at up to 6A (30W), which is enough to power several microcontroller boards, small single-board computers, or logic-level I/O modules. Its 18-75V DC input accepts 24V, 48V, or 72V panel buses, and the 4KVdc isolation protects sensitive digital circuits from bus-side noise.
Is the DDR-30L-5 a good choice for converting a 48V battery bus to 5V for USB charging stations in a mobile or marine installation?
Yes. With 30W at 5V and 6A output, it can supply multiple USB charging ports simultaneously. The 18-75V input range covers 48V battery systems (typical 40-58V range), and the -40°C to +85°C operating temperature makes it reliable in vehicle, marine, or off-grid environments.
Can the DDR-30L-5 power 5V LED indicator strips or small display panels in a DIN rail cabinet?
Yes. At 5V and 6A it provides enough current for addressable 5V LED strips or small LCD/OLED display modules used in status panels. The DIN rail mount and 35mm slim width make it easy to integrate into existing cabinets without taking up significant space.
Will the DDR-30L-5 handle the wide temperature swings of an outdoor telecom cabinet?
Yes. It is rated from -40°C to +85°C, which covers the full temperature range of outdoor telecom shelters and roadside cabinets in most climates. The fanless design eliminates filter maintenance concerns in dusty or sandy environments, though the unit should be housed in an appropriate enclosure since it does not carry an IP ingress rating.
How does the DDR-30L-5 differ from the DDR-30G-5 in terms of input range?
Both models output 5V at 6A (30W) and share the same DIN rail form factor. The DDR-30L-5 accepts 18-75V DC input, designed for 48V or 72V bus systems. The DDR-30G-5 accepts 9-36V DC input, designed for 12V or 24V bus systems. Choose based on your upstream DC bus voltage.
