Power adapter/inverter Mean Well RDDW20H-15, 20 W, 15 V output, input 43–160 V, RoHS

Mean Well RDDW20H-15 is a compact DC-DC railway dual output converter that accepts a wide input range of 43–160 VDC and provides bipolar outputs of ±15 VDC at ±0.667 A. The unit is designed for industrial and embedded applications where space and weight are limited; it features 3 kVDC input-to-output isolation, a DIP through-hole package, remote ON/OFF control and RoHS compliance. Its small depth (50.8 mm) and light weight (35 g) make it suitable for volume deployment and rack or board installations.

Advantages

The converter offers wide input voltage tolerance, bipolar regulated outputs for systems requiring both positive and negative rails, and high galvanic isolation (3 kVDC) between input and output for safety and noise rejection. The through-hole DIP package simplifies PCB mounting in industrial controllers, and the remote ON/OFF feature enables easy system-level power control. RoHS compliance ensures compatibility with environmental standards.

Suitable for

• Railway and transportation control electronics
• Industrial embedded systems and automation equipment
• Signal conditioning and instrumentation needing ±15 V rails
• Space-constrained PCB installations and module replacement

How to use

Mount the DIP through-hole converter on the PCB following the manufacturer’s recommended footprint and observe correct input polarity when connecting the 43–160 VDC supply. Connect load circuits to the ±15 V outputs ensuring the combined output current does not exceed ±0.667 A per rail. Use the remote ON/OFF pin to control power delivery from a system logic signal according to the product datasheet timing and logic level requirements. Maintain proper creepage and clearance distances when integrating into panels to preserve the 3 kVDC isolation rating.

Recommendations

For reliable operation, operate the module within specified input and output limits, provide adequate cooling or airflow in confined installations, and consult the official Mean Well datasheet for detailed wiring diagrams, pin assignments, and thermal derating curves before final assembly.
