Virtalähde MEAN WELL SKMW20G-05 20W tulo 18-75V lähtö 5V

The MEAN WELL SKMW20G-05 is a compact DC-DC converter designed for PCB mounting. It accepts a wide input range of 18–75 VDC and provides a regulated single output of 5 VDC at up to 4 A in a 1" x 1" DIP through-hole package. The module is ultra-compact and includes a remote ON/OFF control for integration into systems requiring controlled power sequencing.

Advantages

The SKMW20G-05 offers a wide input voltage span that supports varied supply sources, a high output current capability within a small footprint, and a standardized DIP through-hole form factor for straightforward PCB assembly. It is lightweight and RoHS-compliant, which simplifies use in equipment with space and weight constraints while meeting environmental directives.

Suitable for

• Embedded systems and single-board computers requiring 5 V power
• Industrial control modules and instrumentation
• Telecommunications and remote equipment with variable input supplies
• Prototyping and low-volume production with through-hole assembly

How to use

Mount the SKMW20G-05 into the PCB using the DIP through-hole leads and solder according to standard PCB assembly practices. Connect an appropriate input source within 18–75 VDC to the input pins, and take the regulated 5 VDC output from the output pins, observing correct polarity. Use the remote ON/OFF pin to enable or disable the output as required by your system's power sequencing. Follow the manufacturer's recommended clearance, grounding, and heat dissipation guidelines when integrating the module.

Recommendations

Ensure the input supply remains within the specified 18–75 VDC range and that the load does not exceed 4 A continuous. Provide adequate PCB copper area or heatsinking if the application approaches maximum power to maintain reliable operation. Verify remote ON/OFF logic levels against your control circuitry before connecting.
