CR6300 Series power factor transducers from CR Magnetics Inc., St. Louis, MO, sense the phase angle difference between AC current and voltage signals and can be used in motor loading, measure timing, and correcting power factor. The transducers are available in 3 basic model styles: CR6310-500V with a 0–5 VDC output, the CR6311-500V with a 0–10 VDC output, and the CR6320-500V with a 4–20 mA DC output. Features include the ability to measure ±90° phase differences, 5 kHz bandwidth, window openings that accommodate current-carrying wires up to 0.26 in. dia., and input ranges that can be extended using CTs and PTs.
