Instrument transformers (PIN version)
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 (ELECTRICAL)
- Electrical
- PIN connection 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)
- Low phase error for power measurement
- Very low remagnetization losses and
- Eddy current losses
- Use of nanocrystalline and high-quality cores
- Electrically isolated primary and secondary circuits
- Assembly-friendly designs
- Wide range of housings with various push-through openings
Unique Selling Point
- assembly-friendly designs
- Versatile range of housings with different push-through openings
