T-PF1, T-PF3 Phase Angle Transducers
Models T-PF1 & T-PF3

T-PF Phase Angle (Power Factor) Transducers

The T-PF1 & T-PF3 phase angle (power factor) transducers convert ac sinusoidal current and voltage input signals into a load independent dc signal proportional to the phase angle between the current and voltage waveforms.
