Thiết bị theo dõi bức xạ mặt trời Middleton Solar APT-02, AST-02, AST-03
The horizontal axis and the vertical axis are each rotated by a stepper motor that is directly connected to a harmonic gearhead with zero backlash.
The GPS signal is used to automatically configure the Tracker for any geographic location and to provide precise time synchronization.
The Tracker operates on 12VDC, and has low power requirement of less than 10W, making it suitable for solar powered sites.
The image above shows the APT-02 Tracker with the optional LP01 Levelling Plate and available DN5-B Pyrheliometer.
