Description:

Designed for electronic current measurement: DC, AC, pulsed, etc., with galvanic isolation between the primary and secondary circuits.

Main Features:

  • Closed-loop (compensated) current transducer using the Hall effect
  • Insulating plastic housing compliant with UL 94-V0
  • Excellent accuracy
  • Very good linearity
  • Low temperature drift
  • Optimized response time
  • Wide bandwidth
  • No losses Insertion Loss
  • High immunity to external interference
  • Capacity of current overload

Applications:

  • Variable speed AC drives and servo motors
  • Static converters for DC motor drives
  • Battery-powered applications
  • Uninterruptible power supplies (UPS)
  • Switched-mode power supplies (SMPS)
  • Power supplies for welding applications
