## Long description

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
