MEAN WELL DDR-30G-12 nätaggregat och spänningsomvandlare, 30 W

The MEAN WELL DDR-30G-12 is an ultra-slim industrial DC-DC DIN-rail converter that accepts an input range of 9–36 V DC and delivers a single 12 V DC output at up to 2.5 A (30 W). Its compact housing (35 mm × 54.5 mm × 90 mm) is designed for space-saving installation on standard DIN rails and it complies with RoHS environmental requirements. The model is intended for industrial control, automation and other equipment requiring a stable 12 V supply and is supplied in bulk packs of 96 units.

Advantages

The DDR-30G-12 combines a narrow profile with an industrial-grade design to provide reliable 12 V power in confined panel spaces. It supports a wide input voltage window (9–36 V DC) suitable for battery-backed systems and vehicular or industrial power sources, and delivers up to 2.5 A output current. RoHS compliance and standardized DIN-rail mounting simplify regulatory and installation requirements for system integrators and maintenance teams.

Suitable for

• Industrial control panels and PLCs
• Automation equipment and sensors
• Battery-backed systems and vehicles with 9–36 V supplies
• Embedded systems and communication modules requiring 12 V

How to use

Mount the converter on a standard DIN rail inside the equipment cabinet. Connect the input terminals to a 9–36 V DC source, observing correct polarity and using appropriately rated wiring and fuses. Connect the 12 V DC output to the load, keeping cable runs short to minimise voltage drop. Ensure the unit has adequate ventilation and is installed in accordance with local electrical standards and the MEAN WELL wiring recommendations.

Recommendations

Verify input voltage and current requirements of connected devices before installation. For long cable runs or higher load currents, use thicker conductors or local regulation to prevent voltage drop. Follow MEAN WELL datasheet instructions for ambient temperature limits and necessary protective measures such as fusing and transient protection.
