DC Current Transformers with CTid

$199.24 to $223.39


The eGauge Sensor Hub is required. A single sensor hub can support up to four DC CTs. 

The ESD series are bidirectional, split-core DC CTs. Applications for DC measurements include battery monitoring, solar string monitoring and other systems that utilize DC power.
eGauge DC CTs use CTid technology for auto-detection and have an onboard LED which can be used to identify which CT is connected to a given sensor port. This is useful if the CT leads cannot be traced.
eGauge DC CTs are compatible with eGauge Core and Pro models and require the eGauge Sensor Hub. eGauge DC CTs are CE certified and are a UL recognized component.
