Single Phase Digital Power Meter , Led Display Electric Power Meter Intelligent Reactive
1. Product Introduction:
Series of WD-9Q1 Single-phase Power Meters are used for measuring and monitoring the power distribution system. This series of meter can measure the voltage, current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy and some other power parameters.
It combines the measurement, the analysis and the operation together, makes the information become clearer, and the operation become easier.
