Trek PZD350AMS User Manual
Trek Model PZD350A M/S
Piezo Driver/Power Amplifier
Trek’s PZD350A M/S Piezo Driver/Amplifier system provides
precise voltage control and delivers twice the current of our
standard PZD350A. This high-voltage DC-powered amplifier
offers voltages that can will be factory set to customer-specified
ranges. It features an all-solid state design, impressive slew rates
and superior bandwidth capabilities.
Other features include a four-quadrant active output stage that
sinks or sources current into reactive or resistive loads
throughout the output voltage range, precision voltage and
current monitors, remote access and dynamic adjustment. The
input is configured is inverting but an inverting amplifier
configuration is available.

Notes
The Model PZD350A M/S 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 with half the current capability of
the PZD350A M/S.
