MEAN WELL DDR-15G-3.3 power adapter 15W RoHS certified

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

How to use

Mount the converter on a standard DIN rail inside the control cabinet. Connect the DC input (9–36V) to the input terminals observing correct polarity. Connect the 3.3V output to the load, ensuring the total current does not exceed 3.5A. Provide adequate ventilation and follow local wiring and safety regulations. Verify connections and measure output voltage before connecting sensitive electronics.

Recommendations

The device should be used within the specified input range and load limits; avoid exceeding the 3.5A output current and ensure proper heat dissipation. For critical applications, add protection such as fuses or external filtering as required by the system design.
