Split Core Current Transformers


SKU: N/A Category:


DENT Split Core current transformers are compatible with ELITEpro Series energy data loggers, PowerScout Series power meters, or any meter which accepts a 333mV output CT.

Split Core current transformers provide linear output voltage that is directly proportional to the input current. These transformers are safely and easily installed over existing electrical power lines without disconnecting lines or interrupting service.

DENT’s Split Core CTs are shunted and, therefore, safe compared to other commercially available CTs and produce 333mV at full scale. Cost-effective and easy to use, they are available in three window sizes and for 5A to 1,200A loads. Specified accuracy is 1%.

All DENT CTs are sold individually (not in sets).

All pricing in US Dollars and applies to US customers only. Pricing does not include duties and taxes. International customers, please click here to obtain a quote.
