Nutfield Technology Servo Amplifier QD-2000

Nutfield Technolo gy’s QuantumDrive-2000 Servo Amplifier is a compact, powerful galvanometer amplifier, giving greater performance at the most cost effective price. As the smallest class-0 servo amplifier available, the QD-2000 features a single output power amp configured for maximum performance and electrical efficiency. Quiescent current is little over half that needed for the high power push-pull QD-4000 amplifier. The QD-2000 leverages lower component count, higher signal-to-noise for high accuracy positioning and good temperature stability. Exceptional performance is achieved with PID servo architecture plus advanced terms for extra stability, speed and control. As with traditional systems, a notch filter is selected and tuned for each unique mirror-galvo combination to maximum system bandwidth. The result is faster, more accurate scanning. Lower cost and optimized for high volume OEM applications, the design of the QD-2000 does not sacrifice on performance or features. Onboard status LEDs provide servo status and fault indications. A diagnostic port is available for test, development and monitoring needs. Circuit features include soft start/stop operation, open circuit AGC monitor and under-voltage power supply protection. The QD-2000 also features TTL compatible remote enable and status I/O. QD-2000 Servo Amplifiers are tested and tuned with serial number matched galvanometer and mirror to customer specifications. Together, Nutfield Technology’s galvanometer-based scanning solutions are the strongest and most affordable in their class.
