The Trek® 50/12 DC-stable, high-voltage power amplifier features an all-solid-state design for high slew rate, wide bandwidth, and low-noise operation. It is designed to provide precise control of output voltages in the range of 0 to ±50 kV DC or peak AC with an output current range of 0 to ±12 mA DC or peak AC.

The four-quadrant, active-output stage sinks or sources current to reactive or resistive loads throughout the output voltage range. This is essential to achieve accurate output responses and high slew rates demanded by reactive loads.


  • 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 nearly maintenance-free operation and solid-state design
  • Take advantage of low-output noise and ultra-accurate outputs


  • 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
