The Trek Model 615-10 is a precision high voltage AC/DC generator and amplifier system used in a broad range of R&D and production applications. In the constant voltage mode, the 615-10 generates constant amplitude waveforms with or without DC bias. In the constant current mode, it generates constant amplitude AC current waveforms, with or without DC bias and in amplifier mode, an analog voltage input connector is provided to apply external AC or DC signals. The Model 615-10 provides many extra features, along with Trek's exclusive instrument control and an interface to be used in remote operation. • 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 20 kV DC peak-to-peak 0 to ±10 kV DC 0 to ±10 kV (combined AC and DC instantaneous voltage value) 0 to ±10 mA average where AC current average = (2) I peak / 3.14 0 to ±10 mA DC 0 to ±35 mA peak 100 Hz to 10 kHz Typical Applications Include • Electrophotographic processes • Electrophotographic corotron/scoratron device shielding • Photoconductor industry Features and Benefits • Three modes of operation with or without DC offset bias • Monitor and control photoreceptor charging current with very high accuracy • Four-quadrant output extends frequency response • Operator-selectable sine, square or triangle wave output shape • NIST-traceable Certificate of Calibration provided with each unit • compliant • Trek also provides Model 615-3 which has a 10 kV peak-to-peak capability TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com •
