QD-4000 Servo Amplifier
Small, powerful galvanometer power supply
Nutfield Technology’s QuantumDrive-4000 Servo Amplifier is a small, powerful galvanometer power supply, giving greater performance at the most cost effective price. As the smaller Class-1 servo amplifier available, the QD-4000 features dual output power amplifiers for maximum performance. Low noise components maximize signal-to-noise ratio for better accuracy. Low drift components reduce the effects of temperature variation.

Overview
The architecture of the QD-4000 features PID terms in addition to servo terms for extra stability and control. A notch filter is selected and tuned for each unique mirror-galvo combination to maximize system bandwidth. The result is faster, more accurate scanning.
The circuits of the QD-4000 provide soft start/stop operation, open circuit AGC fail, and over/under voltage protections for laser systems and scanning mirrors. Onboard status LEDs provide service technicians with servo status and fault indications. Diagnostic port available for test and development needs.
QD-4000 Servo Amplifiers are tested and tuned with a matching galvanometer and mirror to customer specifications. Together, Nutfield Technology’s galvanometer-based scanning solutions are the strongest and most affordable in their class.
