The DC-stable Trek® 40/15 high voltage power amplifier features an all-solid-state design, non-inverting configuration, and a fixed gain of 4000 V/V. It is protected against overvoltage and overcurrent conditions that can be generated by active loads or output short circuits to the ground. Precision voltage and current monitors provide low-voltage representations of the high-voltage output and load current for monitoring purposes or use as feedback signals in a closed-loop system.


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


  • Graduated one-turn potentiometer can be used to optimize the AC response for various load parameters
  • Current limit/trip status indicator and connector
  • NIST-traceable calibration certificate provided with each unit
  • DC-stable for programmable supply applications
  • Local and remote high voltage turn on or off capabilities
