Built-in industrial grade microcontroller for stable operation in harsh outdoor environments, including cold, high temperatures, and humidity. Automatically detects 12V and 24V inputs with intelligent voltage recognition for seamless compatibility and added convenience. Large LCD display provides clear, intuitive status and control at a glance. Dual USB outputs enable convenient, fast charging of devices. Comprehensive protection: overcharge protection, over-discharge protection, overload protection, as well as short-circuit and reverse-polarity protection. Broad load compatibility: easy to mount on various streetlights and surveillance devices. Use scenarios - Municipal street lighting and CCTV systems: reliable power management in harsh climates, maintaining stable operation across temperature ranges and moisture. - Remote or off-grid installations: powers cameras, sensors, and lighting with automatic voltage recognition and robust protection for durability in challenging environments. - Field service deployments: technicians power equipment on-site and charge devices via the dual USB ports, reducing setup time and increasing efficiency.
