Transducteurs de tension de la série DVC 1000

For the electronic measurement of voltage: DC, AC, pulsed..., with galvanic separation between the primary and the secondary circuit.

Features

  • Bipolar and insulated measurement up to 1500 V
  • Panel and DIN rail mounting
  • Push-in connections
  • Ingress protection rating IP 20

Advantages

  • Low consumption and low losses
  • Compact design
  • Very low sensitivity to common mode voltage variations
  • Excellent accuracy (offset, sensitivity, linearity)
  • Fast delay time
  • Low temperature drift
  • High immunity to external interferences


Standards

  • EN 50155: 2017
  • EN 50121-3-2: 2016

  • IEC 61800-5-1: 2007
  • IEC 62109-1: 2010
  • UL 508: 2018

Applications

  • AC variable speed and servo motor drives
  • Static converters for DC motor drives
  • Battery supplied applications
  • Uninterruptible Power Supplies (UPS)
  • Power supplies for welding applications
  • Single or three phase inverters
  • Auxiliary converters
  • Substations
