400W Step-up Real-time Tracking Function LED Display Solar Supplys Battery Recharging Controller 24~85V Output Voltage Adjustable IP66 Waterproof Dustproof Grade Overheating Short Circuit Input Undervoltage Overcurrent Protections Function

Features:
With the LED display for you to see the input and output voltage and current, you can check it easily.
The output voltage can be adjusted between 24~85V.
Overheating protections function: When the internal ambient temperature exceeds 100C, it will reduce the output power. If the internal ambient temperature continues to rise to 110C, it will automatically turn off the output. When the internal ambient temperature is lower than 85C, it will automatically resume work.
Short circuit protections function: When an accidental short circuit occurs in the output of the controller, the controller automatically turns off the output, and automatically returns to normal after the short circuit is eliminated.
Input undervoltage protections function: When the input direct current voltage of the controller is lower than 15V, it will shut down protectively and automatically resume work after the input voltage is normal.
It has a high efficiency real-time tracking function and a high-efficiency synchronous rectification solution. It also has the IP66 waterproof and dustproof grade.
