DKMW40F-12

Overview

The MEAN WELL DKMW40F-12 is a 40W isolated DC/DC converter in the DKMW40 series, designed for through-hole mounting. It features a wide input voltage range of 9V to 36V DC and provides dual outputs: +12V at 1.67A and -12V at 1.67A. The unit measures 25.4mm x 25.4mm x 10mm and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Offers dual polarity outputs with standard DIP 1x1 inch footprint and industrial pin layout
• Includes comprehensive protection against short circuit, overload, overvoltage, undervoltage, and overheating
• Features built-in remote ON/OFF control and adjustable output voltage capability

Applications

• Industrial automation systems
• Telecommunications equipment
• Distributed power architectures

Procurement Notes

Verify the specific suffix 'F' against official datasheets to confirm it denotes the through-hole variant rather than surface mount. Ensure the required output configuration matches the dual +/-12V specification. Confirm compliance requirements such as UL or CE are met for the target region before procurement.

Selection Notes

Select this model when a compact, isolated DC/DC converter with dual symmetric outputs is required. It is suitable for applications needing a wide input range and robust protection features. Consider the thermal derating curve if operating near the maximum temperature limit.

Part Context

This component belongs to the DKMW40 series of 40W DC/DC converters from MEAN WELL. The series is characterized by high efficiency and a 4:1 ultra-wide input range. These converters are designed for reliable performance in demanding environments, offering I/O isolation and standard pin compatibility.

Replacement Considerations

The SKMW40F-12 is a surface-mount equivalent within the same family. Verify that the package type (through-hole vs. SMD) aligns with the PCB design. Other models in the DKMW40 series may offer different output voltages but share similar form factors.
