Power adapter/inverter Mean Well RDDW08G-05 — 8 W, Input 18–75 V, Output 5 V

Mean Well RDDW08G-05 is a compact DC–DC converter designed for industrial and embedded applications. It provides a fixed 5 V output with up to 8 W of power from a wide input range of 18–75 VDC. The module features DIP through-hole packaging, remote ON/OFF control and 1.5 kVDC input-to-output isolation for enhanced safety in railway and industrial environments.

Advantages

The RDDW08G-05 delivers regulated 5 V output with low footprint and DIP mounting for easy PCB integration. Wide 18–75 V input accommodates variable supply conditions; 1.5 kVDC I/O isolation increases system safety. Remote ON/OFF allows external control of the converter state. RoHS compliance ensures restricted hazardous substances for industrial use.

Suitable for

• Railway and transportation control systems
• Industrial automation and embedded controllers
• Low-power instrumentation and sensors
• PCB assemblies requiring through-hole DC–DC modules

Key specifications

• Input voltage: 18–75 VDC

How to use

Mount the RDDW08G-05 in a compatible DIP footprint on the PCB and provide the DC input within 18–75 V. Connect the remote ON/OFF control according to the manufacturer wiring (use the control pin to enable or disable the output). Verify correct polarity and grounding before applying power. Observe the rated output current limit (0.8 A) and ensure adequate spacing and airflow for heat dissipation in your enclosure.

Recommendations

Use the converter within the specified input range and current rating; provide adequate clearance and grounding when installing in railway or industrial equipment. For reliable long-term operation, avoid prolonged operation at maximum load and maintain ambient temperatures within the component’s rated range.
