Thek Model 609E-6 High-Voltage Power Amplifier The Model 609E-6 is a DC-stable, high-voltage power amplifier used in industrial and research applications. It features an allsolid-state design for high slew rate, wide bandwidth and low-noise 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, an inverting amplifier or as a differential amplifier. Different input configurations can be wired into the unit. 0 to ±4 kV DC or peak AC 0 to ±20 mA DC or peak AC Greater than 150 V/ps DC to greater than 13 kHz 1000 V/V Key Specifications • Output Voltage Range: • Output Current Range: • Slew Rate: • Large Signal Bandwidth (-3 dB): • DC Voltage Gain: Typical Applications Include • AC or DC biasing • Atmospheric plasma • Dielectric barrier discharge • Electroactive polymers (EAP) • Electrophoresis, electrophotography • Electrorheological fluids • Electrostatic deflection • Electro-optic modulation • Ferroelectric material characterization • Ion beam steering • Mass spectrometers • Material poling and particle accelerators Features and Benefits • Four-quadrant output for driving capacitive loads • Closed loop system for high accuracy • Short-circuit protected for equipment protection • DC-stable for programmable supply applications • Low output noise for ultra-accurate outputs • NIST-traceable Certificate of Calibration provided with each unit • C £ compliant TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com •
