Dehner Elektronik SDS 075M-05 DC/DC Converter Step-Down 9-36V to 5V 12A 60W

Deliver a rock-steady 5 V DC at up to 12 A from a wide 9–36 V input with the Dehner Elektronik SDS 075M-05. This step-down converter achieves up to 95% efficiency, turning surplus voltage into usable power instead of heat, and its convection-cooled aluminium housing keeps it silent and maintenance-free.

Overview

The SDS 075M-05 is a non-isolated buck converter built for demanding industrial and automotive DC systems. It accepts a broad input range of 9–36 V DC, making it ideal for 12 V and 24 V battery banks, solar arrays, or vehicle electrical systems. The output is tightly regulated at 5 V DC with ±1% load regulation and less than 100 mVp-p ripple, ensuring clean power for sensitive electronics. Screw terminals on both input and output allow secure, tool-free wiring in chassis-mount installations.

What stands out

• High efficiency up to 95% reduces energy waste and heat generation.
• Wide 9–36 V input range covers 12 V and 24 V nominal systems.
• Robust protection against short circuits, overcurrent, and overtemperature.
• Convection cooling—no fan, no noise, no moving parts.
• Compact aluminium housing for easy chassis mounting and heat dissipation.
