FEATURES:
Current transformers for electronic watthour meters with DC-tolerance are designed for applications where AC current signals or
half wave rectified DC current signals must be
transformed accurately into a lower current signal
appropriate for micro-processor based circuits.
A new TA model can be designed and manufactured to meet the specific
design challenges of the client's specific application. The following models
are only a small sampling of the many different products which have been
and are currently being manufactured.
Application:
Electronic watthour meters according to IEC 62053 -21, -23 must
have a tolerance to DC current
