The NPC3SG is a 3-channel piezo amplifier for precision control of all Newport Nanopositioning products and other low voltage PZTs. Optimized for usability and versatility, these low-noise piezo amplifiers can supply a permanent current of 40 mA per channel in a voltage range of -20 VDC to 130 VDC. The model NPC3SG is designed for Nanopositioning products with strain gauge position feedback (model numbers ending in SG). It supports open-loop (voltage) control and closed loop (position) control. In both cases, the monitor output provides a voltage signal proportional to the actual position (0-10V). Since the open-loop response of a piezo element is faster than the closed-loop response, it can be advantageous for certain applications to use open-loop voltage control while monitoring the position via the monitor output.
Use the NPC3SG  only for Nanopositioning products ending with SG.


NPC3SG是一个三通道压电放大器，用于精确控制所有新港纳米定位产品和其他低压PZTs。这些低噪声压电放大器在-20 VDC到130 VDC的电压范围内，每通道可提供40ma的永久电流。NPC3SG模型是为具有应变片位置反馈(以SG结尾的型号)的纳米级产品设计的。它支持开环(电压)控制和闭环(位置)控制。在这两种情况下，监视器输出的电压信号与实际位置(0-10V)成比例。由于压电元件的开环响应要快于闭环响应，因此在通过监视器输出监控位置的同时，采用开环电压控制对某些应用可能是有利的。NPC3SG仅用于以SG结尾的纳米级产品。
