Mean Well DDR-15G-3.3 DC-DC Converter - 11.6W - 9~36V in 3.3V out

Yes. The DDR-15G-3.3 accepts 9-36V DC input and outputs 3.3V at 3.5A (11.6W). This is enough to power most microcontroller development boards, small FPGAs, or logic-level interface circuits mounted on or near a DIN rail. The 4KVdc I/O isolation protects sensitive digital electronics from noise on the 24V bus.

Yes. The 4KVdc input-to-output isolation makes it well suited for creating a galvanically isolated 3.3V rail for ADC boards, serial interface converters, or communication modules in data acquisition racks. At 3.5A it has headroom for multiple low-power digital boards sharing the same 3.3V bus.

Yes. A 12V vehicle bus (typically 10-14.4V) is well within the 9-36V input range. The 11.6W at 3.3V/3.5A capacity is sufficient for embedded processors, GPS modules, or communication interfaces in vehicle-mounted or mobile equipment applications.

Yes. It is rated from -40°C to +85°C, covering cold-storage warehouses, outdoor enclosures, and hot factory environments. The fanless design means no moving parts to maintain or replace. Install it inside a protective enclosure to shield it from moisture and contaminants.

Both output 3.3V on an ultra-slim DIN rail package with fanless operation and 4KVdc I/O isolation. The DDR-15G-3.3 accepts 9-36V input and delivers 11.6W at 3.5A, while the DDR-15L-3.3 accepts a different input voltage window and delivers 15W at 4.5A. Choose the variant whose input range matches your DC bus voltage.
