Overview

The Trek® 623B features an all-solid-state design for high slew rate, low-noise operation, and an extensive bandwidth of DC to greater than 10 kHz. It’s 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 accurate output responses and high slew rates demanded by a variety of loads, including highly capacitive or reactive loads.

Designed to provide precise control of bipolar output voltages, the Trek 623B can be used in electrostatic beam deflection, electrooptic modulation, electrophoresis research, piezoelectric poling and driving, and numerous other applications.

Benefits

  • Achieve high accuracy with a closed-loop system
  • Drive capacitive loads via a four-quadrant output
  • Rely on ultra-accurate outputs thanks to low-output noise
  • Safeguard equipment with short-circuit protection
  • Save costs thanks to maintenance-free operation and an all-solid-state design

Features

  • Dynamic adjustment optimizes the AC response for various load parameters
  • NIST-traceable calibration certificate provided with each unit
  • DC-stable for programmable supply applications
  • Local and remote high voltage ON/OFF capabilities
  • Switch selectable for current limit or trip, graduated one-turn potentiometer adjusts from 0 to 40 mA
