Current ratio accuracy +/-2% over the range 50 Hz to 10 kHz.
Custom designed transformers available in this range
Notes
(1) Sensitivity may be reduced by employing a lower value resistor. Sensitivity = Load/Ratio
(2) Available at the equivalent price in other currencies at prevailing exchange rate, discount for six or more
IMPORTANT:
Current transformers should not be operated with the secondary open circuit as very high terminal voltages may be present.
Operation under this condition may permanently damage a transformer and constitute a shock hazard
