these transducers convert the active power or reactive power of asingle-phase of three-phase system with balanced or unbalancedload.
the output signals are a digital and dc analog signal.特性? high accuracy: ±0.2%rd (wh), ±0.25%rd (varh)
? 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
