Samlex 12V to 24V 7A Step-Up DC-DC Converter

The Samlex STEP 7 is a compact step-up converter for systems that need to power 24V equipment from a nominal 12V source. Its switch-mode design raises the DC voltage efficiently without requiring a separate battery bank at the higher voltage. The converter is suited to marine, recreational, commercial, industrial, and OEM installations where a small dedicated 24V load must operate from an existing 12V electrical system. Low energy consumption helps keep the conversion practical in mobile and battery-powered applications.

Electronic protection is built in for overcurrent, overvoltage, and reverse-polarity conditions. Input-side transient suppression helps the converter tolerate the voltage spikes that can occur in vehicle and marine electrical systems. The unit uses 6.3 mm push-on flat-pin connections for straightforward integration into a properly terminated harness. Its non-isolated architecture is intended for applications where a common electrical reference is acceptable.

The enclosure is approximately 5 x 3.5 x 2 in and weighs about 0.8 lb, so it can be mounted near the equipment it serves without taking up much space. Installation should keep the converter dry, ventilated, and away from high-heat components even though the electrical package is compact. Samlex lists CE approval for this model and covers it with a two-year limited warranty. The converter should be treated as part of the power-distribution system rather than as a substitute for upstream branch-circuit protection.

• Provides a dedicated higher-voltage supply from an existing lower-voltage system
• Switch-mode conversion keeps the unit compact and efficient
• Input transient suppression suits mobile electrical environments
• Flat-pin terminals simplify harness integration

Verify that the connected load stays within the converter’s continuous output capability before selecting conductor size and branch protection. Keep both input and output cable runs short enough to avoid avoidable voltage loss at the equipment. For more regulated DC conversion choices, browse more DC-DC Converters & Power Supplies.
