Trek Model 623B
High-Voltage Power Amplifier

  • Output Voltage:
  • Output Current:
  • Slew Rate:
  • Large Signal Bandwidth:
  • 0 to ±2 kV DC or peak AC
    0 to ±80 mA DC or 40 mA peak AC for 1 ms
    Greater than 300 V/µs
    DC to greater than 10 kHz (1% distortion)

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.
