Mean Well DDR-15L-24 DC-DC Converter - 15W - 18~75V in 24V out
Description
Description
The DDR-15L is a compact 15W DIN Rail type DC-DC converter designed for installations powered from 24V or 48V battery and DC bus systems. Its ultra slim 17.5mm (1SU) profile fits standard TS-35 DIN rails, and a 4:1 wide input voltage range of 18~75Vdc covers nominal 24V and 48V DC supplies. With no minimum load requirement, free air convection cooling, and reinforced 4KVdc I/O isolation, the DDR-15L provides reliable isolated power across a -40~+85°C operating range.

Frequently Asked Questions
Can I use the DDR-15L-24 to step down a 48V telecom bus to 24V for door locks or access control devices?
Yes. The DDR-15L-24 accepts 18-75V DC input and outputs 24V at up to 0.63A (15W). This is sufficient to power 24V electromagnetic door locks, access control panels, or small alarm modules in telecom facilities running on a 48V DC bus.
Is the DDR-15L-24 appropriate for supplying 24V to a PLC auxiliary circuit from a 48V battery bank?
Yes. The 18-75V input range covers 48V battery systems with their typical voltage swing. The DDR-15L-24 provides 24V/0.63A, which is enough for low-power PLC I/O modules, status indicators, or small 24V solenoid valves in auxiliary automation circuits.
Can this unit power a 24V LED indicator strip inside a control panel?
The DDR-15L-24 provides 24V at up to 0.63A (15W). This is suitable for short runs of 24V LED indicator strips or panel lighting where total power consumption stays under 15W. For longer LED strip runs requiring more current, consider higher-wattage DDR models like the DDR-30L-24 (1.25A) or DDR-60L-24 (2.5A).
Can the DDR-15L-24 handle high-vibration environments such as railway or mining equipment enclosures?
The DDR-15L-24 is rated for -40°C to +85°C and features a solid-state fanless design with no moving parts, which contributes to vibration resilience. It mounts securely on DIN rail. However, for rail-specific applications, verify that the unit meets the relevant EN 50155 or EN 50121 standards for your deployment.
Can I use the DDR-15L-24 to convert a 24V truck battery system to a regulated 24V for sensitive electronics?
The DDR-15L-24 requires a minimum input of 18V, and a 24V nominal truck battery can dip below that during cranking. If your input voltage stays within 18-75V under all operating conditions, the converter will provide a clean, isolated 24V output with 4KVdc isolation to protect electronics from bus noise and transients.
What DDR series models are available at the 15W power level with a 24V output?
Mean Well offers two 15W/24V DC-DC converters in this series: the DDR-15G-24 (9-36V input, 0.63A) and the DDR-15L-24 (18-75V input, 0.63A). The G variant suits lower-voltage DC buses such as 12V or 24V systems, while the L variant is designed for higher-voltage buses like 48V.
