FU-16 economic 333mv mini split core current transformer for meter

333mv mini Split Core Current Transformer

The model FU-16 split core ct is a 16mm diameter mini split-core current transformer offers 333mV, 100mV-2V and 10mA-200mA at secondary from sensed primary current (0-200A). Without using secondary CT inside of meter, users directly connect FU-16 series current transformer to meter for high accuracy metering application. It enables one meter to be adopted for various current rating by only changing primary CT so it makes compact meter design and reduces developing cost. Also, over-voltage protection circuit is included to offer safe, fast and cost effective installation. It has low phase shift for power measurement. length of the output lead can be customized. This is a economical current transformer.
