Attention: This controller is only suitable for flipping single-axis stage driven by DC brush motor. During the tracking process, the inclination angle must be changed so that the angle can be detected correctly. The motor voltage should be 10-28V, and the current is less than 15A. Performance Characteristics: 1. The sun detection head has a built-in gyroscope chip, which can achieve dual-mode tracking. When it is sunny, it is controlled by precise light detection, and the angle is memorized every ten minutes. When it is cloudy, the angle memorized on the last day is automatically retrieved for attitude tracking. 2. Its LCD screen displays status, and displays various parameters and working status of the controller to the user in the form of rich data. 3. Optional infrared remote control: In addition to the buttons on the controller, you can also manually operate and do parameter settings through the remote control. 4. Clock circuit: Built-in super capacitors, with power-down saving function. It can accurately judge the time of the device and control it accordingly. 5. High-current relay controls the forward rotation, reverse rotation and stop of your motor, and the maximum driving current is 15A. When the user chooses the motor, it is recommended to use the electric actuator with its own limit. 6. Power supply protection function against reverse connection: It can protect the controller in the case of reverse connection of the power supply. 7. The circuit has a motor current detection function, which can monitor the current of the motor in real time and make protection. 8. Optional wind speed sensor: It can control the platform to execute to a specified angle to avoid the wind to protect the platform when encountering strong winds. 9. **Optional 485 communication and host computer control functions, multiple devices (100) can be connected in parallel to a group of 485 communication lines, and the operation and control are carried out through the computer host computer software to improve work efficiency. Due to the complicated installation of the host computer and the driver, it is inconvenient to provide remote guidance to customers overseas. This function is blocked when shipped, but it does not affect the normal use of the device. If you want to use this function, before purchasing. Thank you! Size: A: No Remote Control or Wind Speed Sensor C: With Remote Control,No Speed Sensor B: With Wind Speed Sensor No Remote Control D: w/ Remote Control+Wind Speed Sensor Package Included:1 x Main Controller + Sunshine Senor Have a great time shopping!
