The "F0416" is an intelligent hybrid controller for eco-friendly power generation using solar and wind energy, which adopts "Gamma compensation" impedance control to match the voltage-current characteristics of each wind turbine. By connecting with a buck-boost DC/DC converter, it extracts the performance of the wind turbine through an impedance matching method from the open (o2) level at startup to the maximum rated area. The buck-boost DC/DC converter converts a wide range of wind turbine input voltages from approximately 2V to 80V into a battery-appropriate charging voltage, significantly reducing the load current on the generator and enabling it to achieve maximum power output. 【Features】 ■ Compatible with solar power generation of 300W (12V specification) and 500W (24V specification) ■ Compatible with wind power generation of 300W (12V specification) and 500W (24V specification) ■ Correlation measurement of rotational speed (rpm), voltage, current, and power is possible with the display of the generator's rotational speed ■ Increased braking force with the adoption of FET (PWM) brakes on the 3-phase input side ■ Thyristor brakes are used to prevent overspeed during battery downtime *For more details, please refer to the PDF document or feel free to contact us.

• Solar power generator

This is an educational robot that allows practical experience in hardware, software, and mechatronics, based on learning C language programming for the H8 CPU. A significant advantage of the robot as an educational tool is that it can evaluate technical skills without the need for formal tests; the robot's movements alone can serve as an assessment. Students and engineers involved can also self-evaluate, which fosters expected improvements in skills through self-directed learning. More vocational schools are increasingly adopting it for practical classes and similar purposes.
