Mini Toroidal PCB Mounted Current Transformers

The TA series of PCB Mounted toroidal, solid core current transformers provide an accurate and cost effective sensor for measuring AC electric current. The TA series converts the primary AC current signal to a level suitable for micro-processor based electronic assemblies. The pin-in-hole (PIH) PCB mounted current transformers feature asymmetrical mounting in a compact design. Incorporated into products designed for electric power measurement, electric power quality monitoring, Supervisory Control and Data Acquisition (SCADA), the TA series offer superior accuracy and linearity.
