White Digital Multifunction Meter Current Voltage Frequency One
Channel Passive Relay
1. Quick Overview:
Series of WD-2IUF 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.
