The IronHorse® GSD8 series of DC drives is a microprocessor-based design with non-volatile memory storage that is programmable with adjustable parameters, programmable alarm outputs and offers a digital closed-loop algorithm for motor control. GSD8 series DC drives are capable of factory or field configurations for a variety of industrial applications. GSD8 DC drives make use of either a pulse accumulation algorithm or a velocity PID algorithm that can be configured as a speed controller, time-based process controller, or follower drive in a master-follower application. GSD8 output power available is 1/2 to 1 HP at 120 VAC input and 1 to 2 HP at 240 VAC input. All units include a large 4-digit LED display; standard 1/8 or 1/4 DIN panel mount versions are available. GSD8 series DC drives start at $405.00.
