QD-4000 Servo Amplifier
Small Configuration, Powerful Performance
Nutfield Technology’s QuantumDrive-4000 Servo Amplifier is a small, powerful galvanometer power supply, giving greater performance at the most cost effective price. Nutfield’s smallest Class-1 servo amplifier, 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.
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.
The 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.
