Power adapter/inverter Mean Well RDDW20G-15 — 20 W, 15 V output, input 18–75 V, RoHS, 35 g

Mean Well RDDW20G-15 is a compact DC-DC converter designed to deliver a stable 15 V output from a wide input range of 18–75 V. This 20 W module comes in a DIP through-hole package, weighs 35 g and provides reliable isolation and control features for low-power industrial and embedded applications.

Advantages

The converter offers dual output capability with ±15 V rails at ±0.666 A, 1.5 kVDC input-to-output isolation and a remote ON/OFF control. Its wide 18–75 V input range and RoHS compliance make it suitable for varied supply conditions while the through-hole DIP package simplifies PCB mounting and mechanical stability.

Suitable for

• Embedded systems and industrial control boards
• Railway and transportation electronics requiring isolated supplies
• Signal conditioning and analog front-end circuits needing ±15 V rails
• Low-power converters in distributed power architectures

How to use

Mount the RDDW20G-15 into a compatible PCB through-hole footprint, observe correct polarity for input and output connections, and provide a suitable heatsinking or airflow as required by your application. Use the remote ON/OFF pin to control the converter state from system logic. Verify wiring and insulation when connecting to higher-voltage sources and follow standard safety practices for isolated DC-DC modules.

Recommendations

For reliable operation, place the module away from heat sources, ensure proper clearance for the 1.5 kV isolation, and add input filtering if the supply is noisy. Confirm output loading does not exceed ±0.666 A per rail and consult Mean Well documentation for detailed application notes and thermal considerations.
