This is box title
The ASU-50000 unit provides voltage and current output for motor unit of antenna series ASX-21xx. It converts input mains supply AC single phase to three-phase for motor supply, adjusting frequency to control rotation speed.
The internal inverter is based on a vector control system, giving outstanding speed and torque performance and fast response.
The unit provides 2 contact closures for connection with external systems as programmable input to control start and stop of rotation and selection of rotation speed between two preprogrammed values.
