The TA series of toroidal, solid core current transformers provide a highly 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.

Features:

• Operating Frequency: 50Hz to 400Hz
• Operating temperature: -25ºC to +55ºC (Optional: -40ºC to +85ºC)
• CE Approved
• RoHS Compliant
