| - | The bidirectional nature of the power supply allows the motor drives to regenerate power back into the grid when decelerating the dish. 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. See the datasheet {{ : | + | 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 certain scanning/ |
