Power adapter/inverter mean well RSDW08G-12, 8 W, input 18–75 V, output 12 V

Mean Well RSDW08G-12 is a DC-DC railway single output converter designed to convert a wide DC input range (18–75 VDC) to a regulated 12 VDC output at up to 0.666 A (8 W). The module provides 1.5 kVDC input-to-output isolation and is offered in a DIP through-hole package with a remote ON/OFF feature. It is RoHS compliant and intended for embedded systems, industrial controls and equipment that require a stable 12 V supply.

Advantages

The RSDW08G-12 delivers a compact 8 W power conversion with wide input range compatibility and 1.5 kVDC isolation, enabling safe interfacing between different voltage domains. Its DIP through-hole package simplifies mounting in legacy PCBs and industrial boards, while the remote ON/OFF control allows external power management. The converter is RoHS certified and supplied in bulk for production deployment.

Suitable for

• Embedded systems and single-board computers requiring 12 V from wide DC rails
• Industrial control equipment and automation systems
• Railway and transportation electronics with DC supply ranges
• OEM production where through-hole mounting and bulk supply are preferred

How to use

Install the RSDW08G-12 into a compatible through-hole footprint on the PCB, observe correct polarity on input and output terminals, and ensure adequate spacing for isolation. Connect the DC input within the 18–75 V range and verify the output provides 12 V before connecting sensitive loads. Use the remote ON/OFF pin according to the manufacturer wiring notes to control the converter from an external signal.

Recommendations

Operate the converter within specified input and output limits, provide proper PCB clearance and creepage distances for 1.5 kV isolation, and ensure adequate ventilation or thermal management for continuous 8 W operation. Verify remote ON/OFF logic levels from the datasheet before integration into control circuits.
