MEAN WELL DDR-15G-12 Power Supply

The MEAN WELL DDR-15G-12 is an ultra-slim industrial DC-DC DIN-rail converter that delivers a single 12V DC output at 1.25A from a wide 9–36V DC input range. With a compact housing (90 mm height, 54.5 mm depth) and a lightweight construction (86 g), this 15W module is designed for space-constrained control cabinets and industrial automation installations. It is RoHS-compliant and is supplied in bulk packaging suitable for larger projects.

Advantages

The DDR-15G-12 combines a slim DIN-rail form factor with a stable 12V output and a wide input voltage range, allowing use with various battery and vehicle power sources. Its small footprint and low weight simplify mounting in crowded enclosures, while RoHS compliance supports environmentally conscious installations. The rated 15W power and single-output topology make it suitable for powering sensors, small controllers, and auxiliary equipment.

Suitable for

• Industrial control panels and automation systems
• Battery-powered equipment and vehicle electronics (9–36V DC input)
• Sensors, small PLCs and auxiliary devices requiring 12V DC
• OEM assemblies and bulk procurement for installers

How to use

Mount the DDR-15G-12 on a standard DIN rail inside the control cabinet. Connect the DC input within the specified 9–36 V range to the input terminals, observing correct polarity. Take the 12 V DC output from the designated output terminals to power the intended device, ensuring the load does not exceed 1.25 A. Follow the installer manual for wiring, grounding, and any required protection components such as fuses or circuit breakers.

Recommendations

Install the converter in a well-ventilated area away from heat sources and moisture. Verify input voltage and inrush conditions before final connection, and use appropriate overcurrent protection. For long-term reliability, operate the unit within its rated temperature range and avoid exceeding the 15W power rating.
