Overview
The MEAN WELL DKMW40G-12 is a 40 W dual-output DC/DC converter in a DIP-8 through-hole package. It accepts an input voltage range of 18 V to 75 V, with a nominal rating of 48 V. The unit provides two isolated outputs of ±12 V, each delivering up to 1.667 A. It features 2 kV DC I/O isolation and operates within a temperature range of -40 °C to +80 °C. Dimensions are 25.4 mm x 25.4 mm x 10 mm.
Feature Summary
- Offers a 4:1 wide input voltage range without minimum load requirements
- Includes built-in remote ON/OFF control and ±10% adjustable output voltage
- Provides comprehensive protection against short circuit, overload, overvoltage, undervoltage, and overheating
Applications
- Industrial automation systems
- Telecommunications equipment
- Distributed power architectures
- Transportation applications
Procurement Notes
Verify the specific suffix 'G' corresponds to the required regulatory approvals and pin configuration for your design. Confirm that the DIP-8 footprint matches your PCB layout constraints. Ensure the 18 V to 75 V input range aligns with your system's supply capabilities. Check for any additional certification requirements such as UL or CE depending on the target market.
Selection Notes
Select this component when a dual symmetric output is required from a wide DC input range. It is suitable for industrial environments due to its extended temperature rating and robust protection features. Consider the physical dimensions and through-hole mounting method during mechanical integration. Verify that the 40 W total power budget meets the load demands of both channels simultaneously.
Part Context
This model belongs to the DKMW40 series by MEAN WELL, designed for high-efficiency power conversion in compact spaces. The series utilizes a standard 1" x 1" DIP footprint to facilitate easy replacement in existing designs. It targets applications requiring reliable isolated power distribution in harsh industrial conditions.
Replacement Considerations
SKMW40G-12 serves as a single-output variant within the same series. Other models in the DKMW40 family may offer different output voltages or current ratings while maintaining the same form factor.
