Trek Model 5/80
High-Voltage Power Amplifier
The Model 5/80 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 lownoise 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.)
Remote
TTL compatible input. TTL high (or open) turns
off high-voltage output. TTL low turns on highvoltage output
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. A
graduated 1-turn panel potentiometer is used to
adjust limit or trip level from 0 to ±80 mA
Out of Regulation
Indicator illuminates and BNC provides TTL low
when the high-voltage output fails to produce
required HV output (e.g. during a current limit)
Trip Status
Illuminates and a TTL low is provided when the
high-voltage output is disabled due to the
output current exceeding the trip level, the
detection of a high-voltage supply fault for the
removal of the top cover
Fault Status
TTL low is provided when out of regulation for
greater than 500 ms.
