DC-PRO 400 24/12V NOISE-FREE CONVERTER 4ZDCPRO400

The converter steps down voltage from 24V to 12V without interference, ideal for sensitive loads

The device operates stably even with input voltage fluctuations – it functions correctly within an input range of 15V to 30V, ensuring it will not shut down during engine start-up or under battery load. The output maintains voltage between 12–14V, with a maximum of 13.8V – exactly what CB radios, car refrigerators, and Webasto heaters require.

There are no switching noise spikes that could affect radio signals or sensitive electronic circuits. Additional filters and an interference-free design ensure no interference with GPS, radios, or other vehicle devices – even when multiple loads are connected simultaneously.

Automatic protection systems – no need to worry about voltage surges

If the input voltage exceeds 30–33V (e.g., due to alternator failure), the converter automatically shuts down. If the voltage drops below 18–21V (e.g., due to a depleted battery), it also activates protection – preventing operation at excessively low voltage, thereby safeguarding both the load and the converter itself.

It also includes overload, short-circuit, and over-temperature protection – no additional fuses are required. Continuous current is 30A (i.e., max. 400W), with a peak current capability of up to 35A – sufficient to start a refrigerator or mini-vacuum without shutting down the unit.

Operates in extreme conditions – not just on summer days

Operating temperature: from -25°C to +55°C. This means you can install it in a truck in winter in Poland or in a service vehicle in southern Europe – it will neither overheat nor freeze. Cooling is efficient, and dimensions (148x82x48 mm) allow installation in tight spaces – under the dashboard, behind panels, or in a tool box.

Terminals are screw-type – easy to connect and securely hold wires. There are no plastic sockets that could loosen due to vibrations.

No additional regulator or filters are needed – everything is built-in. This is not a "simple reducer"; it is a professional module designed for those who require reliable operation of connected devices throughout the entire journey.
