Prodyn Current Transducers I-300 Series (0.22″ aperture)

Prodyn Current Transducers I-300 Series (0.22″ aperture)


The I-300, I-310 and I-320 wideband current probes were designed to facilitate current measurements on conductors where space is limited. The convenient size and shape make them quick to install over existing conductors that are inconvenient to pass through a fixed-window type probe. The aperture of .220″ diameter allows for testing cables up to RG-58.

The relationship between the sensed current and output voltage is: Vout = ZT x Isensed,  where ZT = transfer impedance
