Trek 20/20C-HS Series


High-Speed, High Voltage Amplifier, Output Voltage 0 to ±20 kV DC or Peak AC

The non-inverting Trek® 20/20-HS high voltage amplifier features an all-solid-state design, high slew rate, ample bandwidth, and low-noise operation. Its four-quadrant, active output stage sinks or sources the current into reactive or resistive loads throughout the output voltage range. For demanding highly capacitive or reactive loads, this type of output is essential to enable accurate output responses and high slew rates.


  • DC-stable for programmable supply applications
  • NIST-traceable calibration certificate provided with each unit
  • Short-circuit protection for safeguarding equipment
  • CE compliant (230 VAC unit only)
  • Local and remote high voltage On/Off capabilities


  • Achieve high accuracy with a closed-loop system
  • Drive capacitive loads via a four-quadrant output
  • Rely on ultra-accurate outputs thanks to low-noise operation
  • Take advantage of nearly maintance-free operation and solid-state design
  • Reliably use in various applications
