The Power Supply / Antenna Motor Driver is the physical base for the Basic Radar Training System. Several modules of the system are designed to be stacked on top of it, side-by-side. The power supply distributes three unregulated dc voltages to the stacked modules through self-aligning connectors. These voltages are regulated within each module to provide the required voltages. Three regulated dc voltage outputs are also available through miniature banana jacks on the front panel of the power supply.

The antenna motor driver supplies power to the Rotating-Antenna Pedestal. It is a Pulse-Width-Modulated (PWM) motor driver that uses a four-quadrant chopper requiring a command signal from the antenna controller or radar target tracking system. It is equipped with front-panel test points for training purposes.
