RWQ system Active + Reactive power (Watt＋Var)
RW system Active power (Watt)
RQ system Reactive power (Var)
These transducers convert the active power or reactive power of a single-phase or three-phase system with balanced or unbalanced loads.
The output signals are isolated load independent DC current or DC voltage, representing the measured value of the active and reactive power.
