DC-DC Converter Voltcraft SDC 2412-5, Input 24 V, Output 13.8 V 5 A

The Voltcraft SDC 2412-5 is a DC-DC converter that converts a 24 V input to a regulated 13.8 V output with a maximum output current of 5 A. It is intended for use where stable 12 V power is required from 24 V systems, such as in automotive, marine and off-grid installations. The converter provides a fixed output voltage suited for charging and powering 12 V devices while incorporating current limiting and thermal protection to maintain reliable operation under varying load conditions.

Advantages

The converter delivers a stable 13.8 V output optimized for 12 V equipment and charging applications while supporting continuous currents up to 5 A. Built-in protections reduce the risk of damage from overload, short circuit or excessive temperature. Compact design and standardized input/output connections simplify installation in vehicles, boats and portable power systems. The unit's regulated output minimizes voltage fluctuation on connected devices, improving performance and prolonging component life.

Suitable for

• Powering 12 V radios and communication equipment from 24 V systems
• Charging 12 V batteries and battery maintenance in dual-voltage vehicles
• Supplying sensors, small controllers and monitoring devices
• Marine and off-grid setups where conversion from 24 V to 13.8 V is required
• Portable or mobile installations with limited space for power electronics

How to use

Mount the converter in a dry, well-ventilated location close to the 24 V source and the 12 V load, observing correct polarity on input and output terminals. Connect the 24 V supply to the input terminals and the 12 V devices or battery to the output terminals. Verify secure mechanical fastening and correct wiring before applying power. After power-up, monitor the output voltage and load current to ensure the converter is operating within specified limits. If the device enters protection mode due to overload or overheating, remove excessive load and allow the unit to cool before attempting to restart.
