## Summary description

MEAN WELL RDDW20F-05 is a 20 W power adapter/inverter with 5 V output voltage and 2 A output current. It is RoHS compliant and designed for compact power conversion tasks. With a depth of 50.8 mm and weight of 35 g, it suits space-limited installations and bulk applications (pack quantity 300). Ideal for powering low-voltage electronics and embedded systems.

## Long description

MEAN WELL RDDW20F-05 is a compact DC-DC railway dual-output converter designed for industrial and embedded applications. It accepts a wide input range of 9–36 VDC and provides isolated ±5 VDC outputs capable of ±2 A. The module features 1.5 kVDC input-to-output isolation, a DIP through-hole package and a remote ON/OFF control, making it suitable for space-limited installations and bulk deployment.
Advantages
The RDDW20F-05 combines a small footprint (50.8 mm depth, 35 g weight) with dual isolated outputs and a wide input range for flexible installation in rail and industrial systems. The 1.5 kVDC isolation improves safety and noise immunity between input and outputs, while the remote ON/OFF pin enables convenient control in automated setups. RoHS compliance supports regulatory requirements for electronic assemblies.
Suitable for
 Powering low-voltage electronics and embedded systems
 Railway and transportation control equipment
 Industrial control modules and signal conditioning
 Space-constrained PCBs and bulk system installations
