Trek 615 User Manual
Trek Model 615 Series
High-Voltage AC/DC Generators
The Trek Model 615A-1 and the Model 615-3 are precision high-
voltage AC/DC generators that can be used in constant voltage,
constant current or external amplifier mode. They are specifically
designed to simultaneously provide the AC and DC operating
potentials required to operate/control an electrostatic charger
roller and offer features such as four-quadrant output, high
rejection of load current noise and three wave output shapes.
The Model 615-10 has the same features with a 20 kV peak-topeak capability. Please refer to the separate 615-10 data sheet
for more information.

Features (cont.)
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 panel potentiometer is used
to adjust limit or trip level from 0 to ±50 mA
Out of Regulation
Status
Illuminates and a TTL low is provided when unit
fails to produce required HV output such as
during current limit or short circuit conditions
Trip Status
Illuminates and a TTL low is provided when the
high-voltage output is disabled due to the
output current exceeding the current trip level,
the detection of a high-voltage supply fault or
the removal of the top cover
Fault Status
A BNC provides a TTL low when the PD05034
is out of regulation for greater than 100 ms
