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-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-to-peak capability. Please refer to the Model 615-10 data sheet for more information. • AC Voltage Range (DC bias is zero): • DC Bias (AC voltage is zero): • AC Voltage + DC Bias: • AC Current (DC current is zero): • DC Current (AC current is zero): • AC + DC Current: • Frequency (Internal Generator): 0 to ±5 kV DC peak-to-peak 0 to ±5 kV DC 0 to ±5kV (combined AC and DC instantaneous voltage value) 0 to 5 mA average where AC current average = (2) I peak / 3.14 0 to 8 mA DC 0 to ±8 mA peak 100 Hz to 10 kHz Typical Applications Include • Dielectric charge material characterization • Polymer and ceramic corona charging • Piezoelectric driving and control Features and Benefits • Monitor and control photoreceptor charging current with very high accuracy • Four-quadrant output for driving capacitive loads • Short-circuit protected for equipment protection • Operator-selectable sine, square or triangle wave output shape • NIST-traceable Certificate of Calibration provided with each unit TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com •
