FU16 economic 333mv mini split core current transformer for meter
Split core current transformers
Current transformer principle is based on the principle of electromagnetic induction. Current transformer is composed of closed core and winding. Its primary winding winding few, string in the need to measure the current line, it often has all the current flowing lines, the secondary winding more turns, in series with the measuring instruments and protection circuit, When the current transformer is working, its secondary side circuit is always closed, so the impedance of the measuring coil and the protective circuit in series is very small, and the working state of the current transformer is close to short circuit. Current transformer is the primary side of the current into a secondary side of the small current to use, the secondary side can not be open.
Applications
FU-16 series of split-core current transformer offers 333mV, 100mV-2V and 10mA-200mA at secondary from sensed primary current. Without using secondary CT inside of meter, users directly connect FU-16 series 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.
Features
The current transformer with high strength PVC shell, all cast bus structure. Transformer directly stuck in the cable Three rubber rings to resist the cable and cable with one. Transformer core using high-quality silicon steel roll, the second wire wound evenly on the core. Transformer open structure can not cut off the cable installation
