Power adapter/inverter MEAN WELL RDDW20F-05, 20 W, 5 V, 2 A, RoHS, 50.8 mm depth, 35 g

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

How to use

Mount the DIP through-hole module on the PCB following the manufacturer’s recommended footprint and maintain proper clearance for isolation. Apply an input voltage within 9–36 VDC to the input terminals and observe correct polarity. Use the remote ON/OFF pin to enable or disable outputs as required by the system; consult the MEAN WELL datasheet for logic levels and connection details. Verify output voltages under expected load conditions and ensure adequate thermal management in enclosed or high-temperature environments.

Recommendations

For reliable operation, follow MEAN WELL’s installation guidelines: provide sufficient creepage and clearance according to system voltages, use appropriate input filtering and transient protection on the supply, and avoid exceeding the specified output current. When used in railway or transportation applications, validate the module within the complete system and perform EMC and safety testing per applicable standards.
