## Summary description

MEAN WELL RSDW20H-05 is a 20 W power adapter/inverter designed for applications requiring a stable 5 V output. It accepts a wide input range of 43–160 V and complies with RoHS. Compact (depth 50.8 mm) and lightweight (35 g), it suits industrial and embedded systems where space and reliable low-voltage supply are important. Supplied in packs of 300 pieces.

## Long description

MEAN WELL RSDW20H-05 is a DC-DC railway single output converter providing a regulated 5 VDC output at up to 4 A from a wide 43–160 VDC input range. The module features 3 kVDC input-to-output isolation, a DIP through-hole package with a compact 50.8 mm depth and a lightweight 35 g construction. It includes a remote ON/OFF control and is RoHS compliant, making it suitable for industrial and embedded systems that require a small, reliable 5 V supply.
Advantages
The RSDW20H-05 offers a wide input range compatible with railway and industrial DC supplies, high isolation between input and output for enhanced safety, and a compact DIP through-hole form factor for straightforward PCB mounting. Its remote ON/OFF function allows external control of the output, and the low weight and small depth facilitate use in space-constrained installations. RoHS compliance ensures it meets common environmental standards.
Suitable for
Embedded control systems in rolling stock and railway equipment
Industrial automation modules requiring a stable 5 V rail
Communication and signalling devices powered from high-voltage DC busses
PCB-mounted power supplies in compact electronic assemblies
Key specifications

Compliance: RoHS
How to use
Mount the RSDW20H-05 on a PCB using the DIP through-hole pins and ensure proper soldering for mechanical stability and electrical contact. Connect the high-voltage DC input within the specified 43–160 VDC range to the designated input pins, and take the regulated 5 VDC output from the output pins. Use the remote ON/OFF pin to enable or disable the output from external logic or a switch; follow the manufacturer’s pinout and control logic levels. Observe correct polarity and grounding practices and provide adequate clearance and creepage distances on the PCB for the 3 kV isolation rating.
Usage recommendations
Ensure adequate board-level creepage and clearance for high-voltage input lines, add input filtering if the system environment is noisy, and verify thermal conditions in the final enclosure to keep the converter within its rated operating temperature. For batch installations, follow MEAN WELL’s datasheet for pinout, mechanical dimensions, and recommended footprint.
