The Trek® PZD350A M/S piezo driver and amplifier system provides precise voltage control and delivers twice the current of Advanced Energy’s Trek PZD350A. In addition to superior bandwidth capabilities, it features an all-solid-state design and impressive slew rates. Voltages for this DC-powered amplifier are factory set to your specified ranges. And a four-quadrant active output stage that sinks or sources current into reactive or resistive loads completely through the output voltage range.


  • Drive capacitive loads via a four-quadrant output
  • Enable high accuracy thanks to a closed-loop system
  • Safeguard equipment with short-circuit protection
  • Benefit from nearly maintenance-free operation and solid-state design
  • Take advantage of low-output noise and ultra-accurate outputs


  • Non-inverting input is standard, but an inverting amplifier configuration is available
  • Remote access
  • Dynamic adjustment
  • Precision voltage and current monitors
  • NIST-traceable calibration certificate provided with each unit

Select specifications are shown below. Please see product data sheet for additional specifications.
