Multi function Power meter
Multi function Power meter
MFP is a multi-line three-phase digital panel meter
for accurate and reliable measurement of electrical quantities (voltage, current,
power, frequency, etc.) in industrial and commercial applications. It has a
large multi-line backlit LCD panel which enables four parameters to be
displayed at the same time. Modbus communication capability allows easy
integration with energy monitoring systems. An expansion module can be fitted
for enhanced functionality (pulse input/output or analogue output).
