Power adapter/inverter Mean Well RSDW20F-15, 20 W, 15 V, 50.8 mm depth, 35 g

Mean Well RSDW20F-15 is a compact DC-DC railway single output converter designed for industrial and OEM applications. It accepts a wide input range (9–36 VDC) and provides a regulated 15 VDC output at up to 1.33 A (20 W). The module features 1.5 kVDC input-to-output isolation, DIP through-hole packaging, and a remote ON/OFF control. Its small size (50.8 mm depth) and lightweight construction (35 g) make it suitable for space-constrained assemblies and electronics projects.

Advantages

The Mean Well RSDW20F-15 offers a compact footprint and low weight while delivering a stable 15 VDC output up to 1.33 A. Wide input voltage range (9–36 VDC) allows operation from various DC sources used in railway and industrial environments. The 1.5 kVDC isolation improves safety and reduces interference between input and output circuits. DIP through-hole packaging facilitates PCB mounting for OEM and assembly processes, and the remote ON/OFF feature enables external control in system designs.

Suitable for

• Railway and transportation electronics requiring isolated DC-DC conversion
• Industrial control systems and automation modules
• OEM assemblies and compact electronic devices with limited space
• Electronics projects and prototypes needing a stable 15 V supply

How to use

Mount the DIP through-hole module on a compatible PCB footprint and secure solder connections according to the manufacturer’s board layout. Apply a DC input voltage within the specified 9–36 V range and verify polarity before powering. Use the remote ON/OFF pin to enable or disable the output from external control logic; follow the manufacturer’s wiring recommendations for correct signal levels. Allow adequate clearance and basic airflow around the module to maintain operating temperature within specified limits.

Recommendations

For reliable operation, ensure the input supply can handle startup currents and avoid subjecting the module to voltages outside the 9–36 VDC range. Use proper PCB layout practices for isolation and grounding, and verify the 1.5 kV isolation requirements for your application. Keep the module within its 20 W output rating and provide adequate mechanical support for through-hole mounting.
