Trek 10/40A-HS Series


High-Speed, Non-Inverting High Voltage Amplifier, Output Voltage 0 to ±10 kV DC or Peak AC

The non-inverting Trek® 10/40A-HS is equipped with a four-quadrant, active output that sinks or sources the 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 highly capacitive or reactive loads. The Trek 10/40A-HS is optimal for electrophoresis, electro-optic modulation, material poling, and numerous other applications.


  • 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
  • CE compliant (230 VAC unit only)


  • Drive capacitive loads via a four-quadrant output
  • Enable high accuracy thanks to a closed-loop system
  • Safeguard equipment with short-circuit protection
  • Benefit from maintenance-free operation and solid-state design
  • Take advantage of low-output noise and ultra-accurate outputs

Amplifier Selection Calculator

To help you select the appropriate Trek amplifier, we created this calculator. It uses peak-to-peak voltage to help calculate values associated with driving capacitive loads. If you have any difficulty with this software or would rather not do the download, please use the step-by-step calculator procedure.
