Passive Current transformer Series IN

Instrument transformers

DESCRIPTION

The growing development and spread of electronic devices with high working frequencies require the use of current transformers with an extended frequency range.
This demand can be met with specially selected materials in conjunction with optimized design.

Advantages

Litz wires or terminals according to UL 94 V-0
Current transformers for precise current measurements
Higher accuracy classes 1; 0.5; 0.2 than with standard IE
Measurements in the frequency range 16 2/3 to -50kHz
Pulse measurement (e.g. 8/20μs)
faible erreur de phase pour la mesure de la puissance
Very low remagnetization losses and eddy current losses
Use of nanocrystalline and high-quality cores
circuits primaires et secondaires séparés électriquement
des formes faciles à monter
Wide range of housings with various push-through openings
