This product is an electrical isolation transducer of single-phase active and reactive power measurement, complete isolation between input and output signals. Through the internal switch can be switched to active and reactive power measurement, with polarity switch-over measurement function simultaneously, can offer unipolarity or bipolarity measurements, no need to distinguish direction of current for unipolarity measurement. Can be widely used in electricity, communications, railways, industrial control and other fields.
