Power adapter/inverter mean well RSDW08G-05, input 18–75 V, output 5 V, 8 W

MEAN WELL RSDW08G-05 is an 8 W DC-DC railway single output converter designed to convert a wide intermediate DC input (18–75 V) to a stable 5 V output at up to 1.6 A. The module provides 1.5 kVDC input-to-output isolation, comes in a DIP through-hole package and includes a remote ON/OFF control. It is intended for use in embedded electronics, industrial control modules and LED driver applications and is RoHS compliant.

Advantages

The converter delivers a fixed 5 V output with up to 1.6 A current from a broad 18–75 V input range, enabling use with various intermediate DC supplies. High 1.5 kVDC I/O isolation improves safety and noise separation between input and output circuits. The DIP through-hole package simplifies mounting in PCB designs where through-hole components are required, and the remote ON/OFF feature allows convenient power control in system installations.

Suitable for

• Embedded electronics and single-board systems
• Industrial control and automation modules
• LED drivers and lighting control circuits
• Railway and transportation power subsystems

How to use

Mount the RSDW08G-05 on the PCB using the DIP through-hole pins and ensure correct polarity on the input and output connections. Apply an input voltage within 18–75 VDC and verify the 5 V output under expected load conditions, not exceeding 1.6 A. Use the remote ON/OFF pin according to the manufacturer’s signal level specification to enable or disable the converter. Observe proper grounding and layout practices to maintain isolation and minimize noise coupling.

Recommendations

For reliable operation, keep the converter within its rated input range and avoid continuous operation at the maximum current without adequate thermal management; provide sufficient board clearance for isolation and follow EMI/EMC layout guidelines in industrial and railway environments.
