Elite 446 is a multi-line three-phase digital panel meter for accurate and reliable measurement of electrical parameters (voltage, current, power, frequency, etc.) for industrial and commercial applications. It has a large multi-line backlit LCD display which enables four parameters to be displayed at the same time. Modbus communication capability allows easy integration with energy monitoring systems. Expansion modules can be fitted for enhanced system integration (pulse inputs/outputs or analogue output and ethernet). Active Total Import / Export Energy. Reactive Import (Q1+Q2) / Export (Q3+Q4) Energy.
