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.


  • 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


  • 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)

Select specifications are shown below. Please see product data sheet for additional specifications.
