600W DC-DC Buck Converter Constant Current

The 600W DC-DC Buck Converter Constant Current module is a high-performance, non-isolated voltage stabilization solution engineered for demanding power management applications. Designed to efficiently step down DC voltage, this buck converter supports a wide input voltage range of DC 12–75V and delivers an adjustable output voltage from DC 2.5V to 50V, making it ideal for a variety of electronic, industrial, and automotive uses.

With a maximum output current of 25A and a peak output power of 600W, this converter is capable of powering high-load devices and systems. For continuous operation, it is recommended to keep the output below 500W, especially at high voltages. The output current is fully adjustable from 1A to 25A, allowing precise control for sensitive loads or battery charging applications. The module features a constant current mode, making it suitable for LED drivers, battery charging, and other applications requiring stable current output.

The 600W DC-DC Buck Converter is equipped with a fan-based heat dissipation system to maintain optimal operating temperatures. If the module temperature exceeds 75°C under load, additional cooling or derating is advised to ensure safe operation. The converter offers short circuit protection based on the set constant current value, but does not include input undervoltage, overvoltage, or reverse polarity protection, so careful installation is essential.

With a typical conversion efficiency of 95%, this module ensures minimal energy loss and reliable performance. The output voltage is easily adjustable via a potentiometer, and an output indicator provides real-time status updates. The compact design (100 x 60 x 35mm) allows for flexible installation in a range of environments.
