Juxta Power Factor Transducers

JUXTA COMBINATION WATT/VAR TRANSDUCERS1.GENERAL
The 2469 and 2489 Power Factor transducers have an analog output corresponding to 1- Cosine of the phase angle of the input current relative to the input voltage signal. The analog output will indicate lead- ing or lagging Power Factor by its direction from center which would be either 0 mA or 12mA based on output selection.
