©2021 Advanced Energy Industries, Inc. The Trek® 677B is a high voltage power amplifier/supply that can operate one of two modes: as a high voltage amplifier when it is configured as a non-inverting amplifier with a fixed gain or as high voltage power supply that responds to front panel controls to command exact output voltage or current. 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. PRODUCT HIGHLIGHTS Operable as a high voltage amplifier (in a non-inverting configuration) or as a high voltage power supply Four-quadrant output for driving capacitive loads Closed loop system for high accuracy Short-circuit protected for equipment protection All solid-state design for maintenance free operation DC-stable for programmable supply applications Low output noise for ultra-accurate outputs NIST-traceable Certificate of Calibration provided with each unit TYPICAL APPLICATIONS Electrostatic beam deflection Electrooptic modulation Electrophoresis research Piezoelectric poling and driving Output Voltage Range 0 to ±2 kV DC or peak AC Output Current Range 0 to ±5 mA DC or peak AC Slew Rate Greater than 15 V/μs Large Signal Bandwidth (-3 dB) DC to greater than 1.2 kHz DC Voltage Gain
200 V/V
High voltage power amplifier/supply designed to provide precise control of output voltages using an all-solid-state design for wide bandwidth, high slew rate, and low-noise.
