Trek Inc.'s new series of power amplifiers have four-quadrant, active-output stage that sinks current into reactive loads throughout the output voltage range. Model 20/20C offers ±20 kV, current capability of ±20 mA, gain of 2000 V/V, a small-signal 3-dB bandwidth of greater than 20 kHz and a slew rate of >350 µV/s. Other available versions are the Model 10/40 with ±10-kV and ±40-mA capability, and Model 5/80, which offers ±5 kV and a current capability of ±80 mA. Industrial and research applications for these amplifiers include dielectric material characterization, polymer and ceramic corona poling, and piezoelectric driving and control.
