QP-X AC Power Transducer

273d025c61fb7e814761e2d38d5d78c3

QP-X AC Power Transducer

QP-X series AC power transducer converts three phase ac signals into a load independent dc signal proportional to voltage(V), current(A), active power (watt) and reactive power (var) Frequency(Hz) etc. Three output signals are combined in one transducer so this ac power transducer can be called 3 phase voltage transducer.

The current and voltage signals are passed into the circuit via precision instrument transformers to provide galvanic isolation between the input circuits and the transducer circuitry. Each pair of current and voltage signals is mathematically multiplied together to produce a product signal proportional to true power and independent of wave shape and phase angle.
