This is a dual-axis solar tracking controller. It uses a high-precision sensor to detect sunlight direction. A microcontroller circuit processes the sensor signal and controls the corresponding relay assembly to drive the platform motors and complete the sun tracking process. The unit also includes functions for leveling in high wind (requires optional air speed sensor), and resetting on cloudy days or at night. An English language LCD displays parameters. Parameters can be set using the keys on the controller or an optional infrared remote. This controller requires a two-degree-of-freedom platform. The platform motors are 12V or 24V DC brush motors. The current for a single motor must be less than 15A (each axis is configured with a 10A fuse by default). Limit switches are required on all four directions of platform movement. Condition: New. Origin: China. Material: Plastic. Color: White and Black. Package Contents: 1 x Main Controller, 1 x Remote Control, 1 x Wind Speed Sensor.
