Power adapter/inverter MEAN WELL RSDW20H-15 — 20 W, 15 V output, input 43–160 V, RoHS

MEAN WELL RSDW20H-15 is a compact 20 W DC-DC railway single output converter with a regulated 15 VDC output at up to 1.33 A. The module accepts a wide input range of 43–160 V (AC/DC compatible) and provides 3 kVDC isolation between input and output. Packaged in a DIP through-hole form factor, it is intended for industrial and embedded applications where space is limited and reliable isolated power is required.

Advantages

The RSDW20H-15 offers a wide 43–160 V input window, high input-to-output isolation of 3 kVDC, and a small through-hole DIP package for easy PCB mounting. It supports remote ON/OFF control and meets RoHS requirements. Its 20 W power rating and regulated 15 V output ensure stable operation for signalling, control electronics, and other onboard systems.

Suitable for

• Railway and rolling-stock power supplies
• Industrial control and automation modules
• Embedded systems requiring isolated 15 V rails
• Replacing or designing isolated DC-DC converters on PCBs

How to use

Mount the DIP through-hole module on the PCB following the manufacturer’s pinout and clearance recommendations. Connect the input within the 43–160 V range, observe polarity where applicable, and connect the regulated 15 V output to the load not exceeding 1.33 A. Use the remote ON/OFF pin to enable or disable the output as required. Ensure adequate creepage and clearance distances and follow railway or industrial installation standards when integrating the converter.

Recommendations

For reliable long-term operation, operate the RSDW20H-15 within specified input and output limits, provide proper PCB thermal management, and verify isolation testing after installation. Use in applications that require a compact isolated 15 V rail and follow applicable railway standards for mounting and wiring.
