About AcuCT mV Series
Why choose a split-core current transformer with a millivolt output?
Split-core current transformers, which feature a removable "leg" for easy, non-intrusive installation, are specifically engineered for retrofit applications. A common secondary output for split core current transformers is 333mV, which is a low-voltage, millivolt output that is inherently safe. Available in a range of sizes, split core current transformers are ideally suited for general energy measurement, submetering, M&V, or other commercial or industrial applications.
