Volver a Vacuumschmelze (VAC)

Vacuumschmelze (VAC) 1000A High-Current Industrial Sensors

Vacuumschmelze 1000A High Current Industrial Sensors are designed for a current of up to 1000Arms with a measuring range of up to 2500Apeak. These VAC Industrial Current Sensors offer low offset and gain errors, low temperature drift, and excellent long-term stability. These sensors also offer low power consumption due to PWM compensation current drive stage. They also offer excellent dynamic properties (rise time, pulse response) due to a low winding capacity of the compensation current winding.

Features

  • Low offset and gain errors, low temperature drift, excellent long-term stability
  • Low power consumption due to PWM compensation current driver stage
  • Wide measuring range up to 2500A
  • 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. 95mm x 34mm x 90mm (L x W x H without baseplate)
  • Large aperture 40x40mm2 (with bevels), giving more space for different primary conductor options (bus bars or bus bar stacks made from Cu or Al, Cables with lugs, etc.)
  • Mechanical and electrical replacement of existing closed-loop Hall-effect sensors without changes in the application
  • 5000:1 turns ratio, current signal output
  • Variants for ±15V-supply and ±24V-supply
  • Variants with different connectors
