产品详细介绍

rwh system watthour
rwwh system watthour+watt
rqh system varhour
rqqh system varhour+var
these transducers convert the active power or reactive power of a single-phase of three-phase system with balanced or unbalanced load. 
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
