Trek PZD2000A User Manual
Trek Model PZD2000A
High-Voltage, High-Bandwidth Power Amplifier
The Model PZD2000A
power amplifier used for precisio n high power
applications. The amplifier incorporates an all-solid-state
design for high reliability and low-noise operation. Its fourquadrant output stage sinks as well as sources load
current throughout the output voltage range, thus
achieving accurate output response and high slew rates,
even into highly capacitive loads.

Features
High Voltage On-Off
Switch selectable for local or remote. Local:
Individual push-button switches; Remote: TTL
compatible input. TTL High turns off high
voltage. TTL low turns on high voltage.
Dynamic Adjustment
Graduated 1-turn panel potentiometer is used
to optimize the AC response for various load
parameters.
Current Limit/Trip
Switch selectable for either limit or trip. Graduated 1-turn potentiometer is used to adjust
current limit or trip level from 10 to 200 mA
Out of Regulation
Status
Indicator illuminates and BNC provides a TTL
low when required high voltage is not provided
such as during a current limit
Trip Status
Indicator illuminates and BNC provides a TTL
low when high voltage output trips due to current trip, detection of fault or removal of cover
Fault Status
BNC provides TTL low when out of regulation
for greater than 500 ms
