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)
- 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
- Designs for easy installation
- Wide range of housings with various push-through openings
- According to: EN/IEC 61869-1/2
- Primary rated current: 50 – 1.000 A
- Frequency range: 50 – 50.000 Hz
