Trek Model 10/40A-HS
High-Speed High-Voltage Power Amplifier
The Model 10/40A-HS is a DC-stable, high-speed, highvoltage power amplifier used in industrial and research
applications. It features an all-solid-state design for high slew
rate, wide bandwidth and low-noise operation. The fourquadrant, active output stage sinks or sources current into
reactive or resistive loads throughout the output voltage range.
This type of output is essential to achieve an accurate output
response and high slew rate demanded by a variety of loads
such as highly capacitive or reactive loads. It is configured as a
non-inverting amplifier.

Features (cont.)
Dynamic Adjustment
Graduated one-turn panel potentiometer is
used to optimize the AC response for various
load parameters.
Limit/Trip Mode
Switch selectable for either limit or trip.
Graduated 1-turn panel potentiometer is used
to adjust limit or trip level from 0 to 100% peak
current. There is one LED indicator and one
BNC connector
