AC Series • Current Transformer Quick Reference Guide
AC Series • Current Transformer Quick Reference Guide
- Current transformers are designed for applications such as sensing overload current, ground fault detection, metering, and analog to digital circuits.
- Features include high-quality production at competitive prices, ISO 9001:2015 and ISO 14001:2015 certification, and full RoHS & REACH compliance.
- Electrical specifications are provided for various models (e.g., AC1005 to AC1200), detailing primary current, turns ratio, terminating resistor, and other parameters.
- Includes dimensions and tolerances for the transformers, with specific notes on pin usage and part number accuracy.
- Talema Group has offices in India, the United States, the Czech Republic, Germany, and Ireland, each handling design, manufacturing, sales, and marketing to varying extents.
- Ratio correction factor (RCF) is used to adjust current readings to compensate for transformer losses.
- Dimensional tolerances are specified as ±0.25mm, with pin pitch tolerance at ±0.10mm.
