SR1004-S（C Ku Ka ）Ctronller
Product Details
1. Product Description
SR1004-S antenna control system is mainly composed of the antenna control unit (ACU) and the antenna drive unit (ADU), and the connection between them can be achieved through network cables or optical fibers. The system communication interface is compatible with RS232/RS485, network ports, optical ports, etc.
Compared with traditional control systems, there are significant improvements in system stability, response time, anti-interference ability, and later expansion compatibility. Additionally, the maintenance and upgrade of the entire system can be fully controlled remotely, and a software one-click upgrade interface is provided to users, offering great convenience for their usage.
Tracking accuracy - Stepped tracking: Under normal conditions, it is superior to 1/10 of the half-power beam width (wind speed 30 meters per hour, gust 45 meters per hour).
l Very streamlined on-site wiring
l Support for Ethernet ports and fiber optic interfaces
l Full software upgrade capability
l Support for extended screen display
l Support for remote access and maintenance

2. Antenna Drive Unit (ADU)
The antenna drive unit (ADU) provides multi-axis drive interfaces for azimuth, elevation, and polarization, among others. The azimuth and elevation axes are suitable for three-phase asynchronous motors. The polarization axis is applicable to single-phase AC motors and can also offer multi-polarization axis drive or linear/Circular polarization axis drive.
l Provide manual control knobs for azimuth, elevation and polarization
l Provide fiber optic interface
l Automatic fault detection
l GPS clock synchronization (optional)
l Full software-based one-click upgrade
