The NPS2100 is a NanoSensor, high voltage amplifier and control electronics combined as a single channel standalone module, powered by an external ±15V, 130V and -30V DC supplies.

The NPS2110 Controller is specifically designed to control Queensgate’s Nanometre Precision NanoMechanisms (the NanoMechanism range or combinations of NanoSensors® and Piezo Translators) in OEM type applications. The control electronics use sophisticated Proportional, Integral and Differential control loop. A Notch filter is also added to remove first order stage resonance. A combination of these loop parameters can be set up to provide faster response from a Queensgate NanoMechanism than that obtained from only Integral loop control.
