DC 6-70V Stabilized Buck Converter

The DC 6-70V Stabilized Buck Converter is a high-performance, constant voltage and constant current CNC DC power supply designed for precision, reliability, and ease of use. With a wide input voltage range of 6.–70V and an adjustable output voltage of .–60V, this converter delivers up to 1200W of power and a maximum output current of 20A, making it ideal for demanding applications in laboratories, workshops, and industrial automation.

Featuring a large, full-view LCD display, this buck converter provides real-time monitoring of voltage, current, and power, ensuring complete control and visibility over your power supply parameters. The device supports serial communication and the standard MODBUS protocol, enabling seamless integration with advanced control systems and remote monitoring setups.

Engineered for safety and durability, the DC 6-70V Stabilized Buck Converter includes comprehensive protection mechanisms such as input overvoltage, undervoltage, output overvoltage, overcurrent, overpower, overtemperature, timeout, overcapacity, and super energy protection. The intelligent cooling fan activates automatically based on load, power, and temperature, ensuring optimal thermal management and extending the lifespan of the device.

With high measurement accuracy (voltage: ±.4%, current: ±.5%), fine adjustment resolution (.01V/.01A), and robust construction, this converter is perfect for battery charging, LED testing, motor drives, and other precision DC applications. The package includes all necessary components for quick setup and flexible use.
