3-channel piezo amplifier, strain-gauge position control

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.
