## Summary description

Mean Well RSDW08G-03 is an 8 W power adapter/inverter with an input voltage range of 18–75 V and an output current of up to 2 A. Designed for converting and regulating DC power in embedded and industrial applications, it complies with RoHS. Typical uses include powering small control electronics, sensors, and communication modules.

## Long description

Mean Well RSDW08G-03 is an 8 W DC-DC railway single output converter designed to convert a wide DC input range into a stable low-voltage output. With an input voltage window of 18–75 V and a regulated 3.3 V output able to supply up to 2 A, this through-hole DIP module provides galvanic isolation between input and output and supports remote ON/OFF control. The unit is suitable for embedded and industrial environments where compact, reliable power conversion is required and meets RoHS environmental standards.
Advantages
The converter delivers a compact 8 W power stage with high input flexibility, making it appropriate for variable-voltage DC systems. Built-in 1.5 kVDC input-to-output isolation enhances safety in rail or industrial installations. The fixed 3.3 V output and 2 A current capability suit digital electronics and communication modules while the DIP through-hole package simplifies mounting and serviceability. Remote ON/OFF functionality enables external control for system-level power management.
Suitable for
Powering small control electronics and microcontroller boards in rail vehicles and industrial equipment
Supplying sensors, communication modules, and low-voltage peripherals requiring 3.3 V
Embedded systems and retrofitting applications where through-hole mounting is preferred
Key specifications
Output power: 8 W
Input voltage range: 18–75 V DC
Output voltage: 3.3 V DC
Maximum output current: 2 A
Isolation: 1.5 kVDC input-to-output
Package: DIP through-hole
Control: Remote ON/OFF function
Compliance: RoHS
How to use
Install the module on a compatible PCB using the through-hole pins and ensure correct polarity for the input supply. Connect the input source within the 18–75 V DC range and verify the wiring to the 3.3 V output load. Use the remote ON/OFF pin according to the manufacturer’s control logic: assert or release the control signal to enable or disable the output as required. Allow appropriate clearance and consider heat dissipation when integrating into an enclosure.
Usage recommendations
For reliable operation, regulate the input voltage within specified limits and avoid exceeding the 2 A output current. Provide adequate decoupling at the output for digital loads and protect the module from conductive debris and excessive vibration typical in rail environments. Follow EMC and grounding practices suitable for industrial systems to maintain stable performance.
