详细介绍

rw active + reactive power (watt＋var)
rw system active power (watt)
r reactive power (var)
these transducers convert the active power or reactive power of asingle-phase or three-phase system with balanced or unbalancedloads.
the output signals are isolated load independent dc current or dcvoltage, representing the measured value of the active and reactivepower.特性? high accuracy ±0.2%rd ±0.1%ro
? precision measurement even for distorted waves
? uses time division multiplier for watt and var
? high immunity to external noise
? wide selection of input and output range
? quick and easy mounting
