CK1 Three Phase Current Converter

The high accuracy CK1 Three Phase Current Transformer (CT) Converters are intended for use in substations and other locations where the standard 1A CT secondary outputs are available, e.g., at test terminal blocks.  The CK1 transforms the 1A CT secondary output current to 200mA, suitable for direct connection to the current input channels of CHK Power Quality instruments.
