## Long description

MEAN WELL RDDW20H-12 is a compact DC-DC railway dual-output converter designed for demanding industrial and vehicle power systems. It accepts a wide input range of 43–160 VDC and provides regulated ±12 V outputs with a combined power rating of 20 W, in a DIP through-hole package with remote ON/OFF and 3 kVDC input-to-output isolation.
Advantages
The RDDW20H-12 offers wide input voltage tolerance (43–160 VDC) and dual ±12 V outputs that deliver stable low-voltage power for control electronics. Its small size (50.8 mm depth) and light weight (35 g) simplify integration into space-constrained assemblies. The device provides 3 kVDC isolation between input and output and includes a remote ON/OFF feature for system control. RoHS compliance ensures compatibility with environmental and regulatory requirements.
Suitable for (tasks / use cases)
 Railway and rolling-stock electronics requiring isolated DC-DC conversion
 Industrial control systems and automation equipment
 Vehicle and mobile power systems with wide DC input ranges
 Powering sensors, instrumentation and low-voltage control circuits
