CURRENT SENSOR TRANSFORMER
PTC-02 SERIES
CURRENT SENSOR TRANSFORMERS
FEATURES AND CHARACTERISTICS
- Maximum ratings specified with rated secondary terminating resistance and one turn primary.
- Amp-micro second (AmSec.) rating of primary equals volt-microsecond (VmSec.) rating of secondary when secondary is terminated in rated resistance. (Amp-microseconds is equal to the product of a square pulse of current in amps times the current pulse width in micro seconds).
- Maximum operating temperature: 105 degree C.
- When terminated with rated terminating resistance the inductor scale factor is V out = 1 volt per amp for center tapped units terminating resistance for each half of winding is listed value divided by 2.
- Secondary is fully isolated to > 2500 V.
- Useful operation to > 100 KHZ.
- Not suitable for measurement of DC current. Current waveform must be free of any DC component.
