Current Transformer The magnetic flux created by the primary current IP is concentrated in a magnetic circuit and measured in the air gap using a Hall device. The output from the Hall device is then signal conditioned to provide an exact representation of the primary current at the output.

Features
Hall effect measuring principle
Galvanic isolation between primary and secondary circuit
Low power consumption
Extended measuring range

Advantages
Easy installation
Small size and space saving
only one design for wide current ratings range
High immunity to external interference

Applications
AC variable speed drives
DC motor drives
Battery supplied applications
Uninterruptable Power Supplies (UPS)
Switched Mode Power Supplies (SMPS)
Power supplies for welding applications
