High Voltage Power Amplifiers

  • Product No:PZD700A-1/PZD700A-2
  • Manufacturer:Trek, Inc.

The Trek Model PZD700A is a high-voltage DC-stable piezo driver/amplifier designed to provide precise control of output voltages in bipolar or unipolar ranges which are customer specified within a range of available settings.  The instrument achieves the accurate output responses and high slew rates demanded by reactive loads by utilizing a four-quadrant active output stage that sinks or sources current into reactive or resistive loads.

The Model PZD700A is configured as a non-inverting amplifier. An inverting configuration is available. Both configurations are available as either single or dual channel instruments. They are bench top operable or 19-in rack mountable.
