Split Core Current Transformer, 330mV output
$7.80 - $57.00Availability: In stockOut of stock
The 330mv AC series of split core current sensors are ideal for installation on existing electrical wiring by snapping around the conductor without requiring and rewiring or interruption of the existing power cabling. UL listed product.
The current flowing through the core of this CT produces an output signal from 0 to 330mv ac, proportional to the current. The signal is a low voltage mv ac signal which needs signal conditioning before going into the typical controller.
The 330mvac signal is compatible with our T3-6CT and the Wattnode power meter on this site.
