Solid Core Current Transformers - AYA Instruments

The AYA solid core current transformers are used in electric power installations for continuously monitoring currents delivered to a load. Their output signal is generally connected to display meters, relays, power monitoring instruments and control systems.  AYA offers an extensive line of solid core current transformers with models that meet UL,CSA, ANSI and IEC Standards. They are available in either commercial class for use with ammeters or metering class for use with current meters, Watt meters, VAR meters and relays where higher accuracy is required. Green Transformers are ROHS Compliant.
