AC2000-D Antenna Control System

AC2000-D antenna control system is suitable for Rotary pedestal antenna drive and control. It works with dual DC servo motor and eliminates the backlash of the rotary pedestal.

AC2000-D ACS adopt DSP technology, including antenna position detection and DC servo motor, PWM is for DC motor speed adjusting and IPM. It adopts multi-circuit hi-speed digital processor, fully digital control from the antenna position detection and control to double DC motor drive away gap. Motor control mode is for pulse width modulation (PWM) dc speed, power amplifier main loop is using intelligent power module (IPM).

Due to the maximum extent of digital and improve the hardware circuit design, the servo system is integrated in a standard 4U * 480 inside the case for convenient transportation and installation of equipment.
