Power adapter/inverter Mean Well RSDW20G-15 20 W, input 18–75 V, output 15 V, RoHS

Mean Well RSDW20G-15 is a compact DC-DC railway single output converter delivering 15 VDC at up to 1.33 A from a wide input range of 18–75 VDC. Designed for embedded and industrial applications, the module offers 1.5 kVDC input-to-output isolation, remote ON/OFF control and a DIP through-hole package that measures 50.8 mm in depth and weighs approximately 35 g. The converter is RoHS-compliant and supplied in bulk for volume installations.

Advantages

The RSDW20G-15 provides a stable fixed 15 V output with a 20 W power rating in a small footprint suitable for space-constrained designs. High I/O isolation enhances safety in railway and industrial environments; the wide 18–75 V input range supports varied power sources. The DIP through-hole form factor enables straightforward PCB mounting, and the remote ON/OFF feature allows external control of the output.

Suitable for

• Embedded systems and PCB-mounted power supplies
• Industrial control equipment and automation
• Telecommunications and mobile power applications
• Railway and transportation electronics requiring isolation

How to use

Mount the DIP through-hole converter onto the PCB according to the manufacturer’s recommended footprint and solder connections. Apply an input voltage within 18–75 VDC and confirm correct polarity before powering. Use the remote ON/OFF pin to enable or disable the output as required by your system. Ensure the module’s thermal and spacing requirements are met and provide appropriate decoupling on input and output lines per application needs.

Recommendations

For reliable operation, keep input voltage within the specified range, provide adequate PCB clearance and thermal management, and follow Mean Well’s layout and grounding guidance. Verify isolation requirements for the intended railway or industrial environment and use the remote ON/OFF feature to integrate safe power sequencing.
