## Long description

The MEAN WELL DDR-15G-3.3 is an ultra-slim DC-DC DIN-rail converter providing a single 3.3V DC output at up to 3.5A from a wide input range of 9–36V DC. With a compact form factor (54.5 mm depth × 90 mm height) and a weight of 80 g, this 15W, RoHS-certified module is intended for industrial control cabinets and space-constrained installations where a stable low-voltage supply is required.
Advantages
The DDR-15G-3.3 offers a narrow housing suitable for standard DIN-rail mounting, a wide input voltage range for compatibility with varied DC sources, and regulated 3.3V output capable of delivering up to 3.5A. Its light weight and RoHS compliance simplify installation and help meet environmental regulations. The unit’s 15W power rating covers many embedded and control applications while minimizing occupied panel space.
Suitable for
Powering low-voltage logic and microcontroller boards in industrial control systems
Supplying sensors, communication modules, and small PLCs within a control cabinet
Use in mobile or battery-backed DC systems with 9–36V input
