 The 3-phase mains power circuit for the motor drives goes to a Meanwell "Bidirectional Power Supply AC to DC 2160W 180-264VAC 48Vdc 45A, DC to AC 1800W 48-65Vdc 37.5A 180-264VAC 1725VA" power supply with model number BIC-2200-48 located inside the base of the SCR-584 rotor.
-The bidirectional nature of the power supply allows the motor drives to regenerate power back into the grid when decelerating the dish, which avoids the need for a resistor bank capable of handling the relatively high average power this would result in under scertain scanning/tracking patterns. In case mains power becomes disconnected or the power supplies fail while the dish is in motion, there is also a Roboteq SR5K100V25R V1.2 active shunt, which clamps excess voltage by dumping power into a bank of power resistors in the event of the bus voltage spiking.
