Napájací zdroj MEAN WELL DDR-30G-5 30W 5V 6A RoHS

The MEAN WELL DDR-30G-5 is an ultra-slim DIN-rail DC-DC converter designed for industrial use. It accepts a wide input range of 9–36 VDC and delivers a single regulated 5 VDC output at up to 6 A (30 W total). RoHS compliant and built to fit narrow control cabinets, the unit measures 35 mm (W) × 54.5 mm (D) × 90 mm (H) and provides a compact, stable power source for devices requiring a 5 V supply.

Advantages

The DDR-30G-5 offers a compact form factor for space-constrained DIN-rail installations, wide input voltage tolerance for use with various vehicle or battery-backed systems, and a regulated 5 V output capable of delivering up to 6 A. Compliance with RoHS standards ensures reduced hazardous substances, and the industrial design supports consistent performance in control and automation environments.

Suitable for

• Embedded controllers and single-board computers that require 5 V
• Industrial control cabinets and automation systems with limited mounting space
• Battery-backed systems and vehicles with 9–36 V input ranges
• Peripheral devices such as sensors, relays, and low-power actuators

How to use

Mount the DDR-30G-5 on a standard DIN rail inside the control enclosure and ensure secure electrical connections to the input and output terminals following the manufacturer’s polarity markings. Apply an appropriate 9–36 VDC supply to the input terminals; measure the output to verify a regulated 5 V before connecting sensitive loads. Provide adequate ventilation and avoid placing the unit near heat sources. Follow all local wiring codes and safety procedures during installation.

Recommendations

For reliable operation, use a properly rated fuse or circuit breaker on the input side, confirm the combined load does not exceed 6 A, and keep ambient temperature within the operating range specified by MEAN WELL. When used in electrically noisy environments, add appropriate filtering or transient protection as needed.
