Power adapter MEAN WELL SKMW20G-15 20 W Input 18-75 V Output 15 V

The MEAN WELL SKMW20G-15 is a compact DC-DC converter module designed for PCB mounting. It accepts a wide input range of 18–75 Vdc and provides a single regulated 15 Vdc output capable of delivering up to 1.33 A (20 W). The module is supplied in a 1" x 1" DIP through-hole package with a low weight of approximately 18 g and includes a remote ON/OFF control. It is RoHS compliant and intended for use where a small, reliable isolated power source is required.

Advantages

The SKMW20G-15 offers a wide input voltage range suitable for varied supply conditions, a compact 1" x 1" footprint for space-constrained PCB designs, and a regulated 15 V output delivering up to 20 W. Its through-hole DIP package simplifies board assembly and mechanical mounting, while the remote ON/OFF feature provides convenient control for system power management. Low weight and RoHS compliance make it appropriate for modern electronic applications.

Suitable for

• Embedded systems and control boards
• Industrial automation modules

How to use

Mount the SKMW20G-15 on the PCB using the through-hole pins and ensure correct polarity and secure soldering of input and output connections. Provide input power within the specified 18–75 Vdc range and connect the remote ON/OFF pin according to your system control logic to enable or disable the output. Observe standard PCB layout practices for DC-DC converters—keep input and output traces short, provide adequate grounding, and place decoupling components as recommended in the manufacturer's datasheet.

Recommendations

Use appropriate input filtering and transient protection when operating from noisy or inductive sources, ensure adequate spacing and cooling on the PCB for reliable operation at full load, and consult the MEAN WELL datasheet for detailed thermal and application guidance.
