The Trek Model 615-3 is a precision high-voltage AC/DC generator that can be used in constant voltage, constant current or external
amplifier mode. It is 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-quadrantoutput, high rejection of load current noise and three wave output
shapes.The Model 615-10 has the same features with a 20 kV peak-to-peak capability. Please refer to the Model 615-10 data sheet for more information.
