Mean Well DDR-30L-12 DC-DC Converter - 30W - 18~75V in 12V out

Yes. The DDR-30L-12 outputs 12V at up to 2.5A (30W), which is sufficient for small sensor arrays, relay modules, and indicator lights commonly found in industrial control panels. Its DIN rail mount and ultra slim 35mm width make it easy to fit into standard enclosures alongside PLCs and terminal blocks.

Yes. With its 18-75V DC input range, it accepts 48V nominal bus voltages commonly found in telecom and data center environments. It provides a stable 12V output at up to 2.5A with 4KVdc I/O isolation, protecting sensitive embedded boards from ground loops and transients on the main bus.

Yes. The wide 18-75V DC input range accommodates the variable battery voltages found in railway and transportation systems (typically 24V, 48V, or 72V nominal). Its -40°C to +85°C operating range and fanless design make it reliable in vibration-prone, maintenance-restricted environments.

The DDR-30L-12 is rated for -40°C to +85°C, so it handles extreme cold and heat inside sealed enclosures without derating concerns at typical ambient temperatures. Its fanless convection-cooled design means no moving parts to fail from dust or moisture. However, it does not carry an IP rating, so it should be mounted inside a weatherproof enclosure rather than exposed directly to rain.

Both the DDR-30L and DDR-30G deliver 30W and share the same output voltage options (5V, 12V, 15V, 24V). The key difference is input voltage range: the DDR-30L accepts 18-75V DC (4:1 wide input), while the DDR-30G accepts 9-36V DC (4:1 wide input at a lower range). Choose the L series for 48V or 72V bus systems, and the G series for 12V or 24V bus systems.
