High Current Sensors

VAC supplements it's high precision current sensor range with magnetic zero field detector with versions for 1000 Aeff, with measuring range up to 2500 A. Target applications are e. g. wind power generation, utility grade solar inverters and large drives.

  • Low offset and gain errors, low temperature drift, excellent long-term stability
  • Low power consumption due to PWM compensation current driver stage
  • Excellent dynamic properties (rise time, pulse response) due to a low winding capacity of the compensation current winding
  • Low dependence of the sensor accuracy on the position of the phase current return conductor in proximity to the sensor
  • Greatest reliability by concentrating the electronic functions in a single monolithic IC
  • Compact dimensions of approx. 95 mm x 34 mm x 90 mm (L x W x H without baseplate), Large aperture 40 x 40 mm² (with bevels)
  • Mechanical and electrical replacement of existing closed-loop Hall-effect sensors without changes in the application
  • Turns ratio: 5000:1, signal output: current
  • Variants for +/-15 V- and +/-24 V-supply
  • Variants with different connectors
