In May 2003, Cedrat Technologies released the LA75B from its electronic lab, a new and powerful linear amplifier for driving its whole range of piezo products. The max output current of 300 mAmp, under 150 Volt per channel, allows the LA75B to explore a 10 times larger frequency range than the LA75A. The LA75B board takes its power from a new AC/DC converter, so called LC75B, delivering a continuous current of 600 mAmp. As a consequence, each LA75B can be equipped with two output channels (see figure) in order to drive any kind of piezo mechanisms (APA, PPA, XY stages,…) presented in Cedrat Technologies’ catalogue. This new LA75B electronic is the first step of a larger project for developing future powerful versions. Nevertheless, the LA75B already offers relevant solution for high frequency actuation, scanning and fast shutter based applications (spectrometry, X ray diffraction, optical switch,…).
