Trek 10-40A User Manual
Trek Model 10/40A
High-Voltage Power Amplifier
The Model 10/40A is a DC-stable, high-voltage 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 four-quadrant, 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
Current Limit/Trip
Switch selectable for either limit or trip.
Graduated 1-turn panel potentiometer is used ti
adjust the limit or trip level from 0 to ±40 mA
Out of Regulation
Status
Illuminates and a TTL low is provided when unit
fails to produce required HV output such as
during a current limit
Trip Status
An amber indicator will illuminate and a BNC
will provide a TTL low when the high-voltage
output is disabled due to the activation of the
current trip or the removal of the top cover
Fault Status
A BNC will provide a TTL low when the Model
10/40A is out of regulation for greater than
500 ms
