Power amplifier 623B

DChigh-voltagelow-noise

The Model 623B is a DC-stable, high-voltage power amplifier designed to provide precise control of bi-polar output voltages. It features an all-solid-state design for high slew rate, low-noise operation and a wide bandwidth of DC to greater than 10 kHz. 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. Key Specifications Output Voltage Range: 0 to ±2 kV DC or peak AC Output Current Range: 0 to ±40 mADC or peak AC Slew Rate: Greater than 300 V/µs Large Signal Bandwidth: DC to greater than 10 kHz (1% distortion) Typical Applications Include Electrostatic beam deflection Electrooptic modulation Electrophoresis research Piezoelectric poling and driving Features and Benefits 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 CE compliant
