MFM with high accuracy, configurability and easy integration

Elite 440 is a multi-line, three-phase digital panel meter for accurate and reliable measurement of electrical parameters (voltage, current, power, frequency, etc.). It is used for both industrial and commercial applications and features a large multi-line backlit LCD display that displays four parameters simultaneously. Modbus communication capability allows easy integration with energy monitoring systems. Expansion modules can be fitted for enhanced system integration (pulse inputs / outputs or analogue outputs and ethernet).
