Trek PZD350A User Manual
Trek Model PZD350A
Piezo Driver/Power Amplifier
The Trek Model PZD350A is a high-voltage DC-stable piezo
driver/amplifier designed to provide precise control of output
voltages in bipolar or unipolar ranges that are customer specified
within a range of available settings. It is configured as a
noninverting amplifier with a variable DC gain. An inverting
amplifier configuration is also available.
The unit features an all-solid-state design, a high slew rate and a
four-quadrant active output stage which sinks or sources current
into reactive or resistive loads throughout the output voltage
range. This capability is essential for achieving the accurate
output responses and high slew rates demanded by reactive
loads.

Notes
The Model PZD350A comes from the factory with settings for an output
voltage of ±350 V DC or peak AC, a voltage gain ratio of 100 V/V, with a
noninverting input. Please specify voltage range (±350 V, +700 V, or
-700 V) and input configuration (inverting or noninverting) when
ordering.
Also available is the Model PZD350A M/S with twice the current
capability of the standard PZD350A.
