The SPS-2722 is an industrial grade, microprocessor-based, servo
controller that weighs 40 pounds. The SPS-2840 is a MIL grade,
Digital Signal Processor (DSP) based, servo controller, weighs 18
pounds, and meets MIL-STD-810 and MIL-STD-461 requirements.
Both controllers provide position and rate-loop control of the
multi-axis gimbal. A firmware download that modifies digital
compensation filters allows the position and rate servo-loops to be
optimised for various payloads. Pulse-Width-Modulated (PWM)
amplifiers within the controllers provide rapid and precise control
of the multi-axis gimbal systems which incorporate brushless,
Standard operating power options include: 115/240 VAC, 50/60 Hz;
208 VAC, 50/60 Hz; 24/28 VDC.
