Multi-function Instrument

Elite 440 is an advanced three-phase multi-line multi-function panel instrument for accurate and reliable measurement of electrical quantities for industrial and commercial applications.

Elite 440 has a large backlit LCD display which enables four parameters to be displayed at the same time. Modbus communication capability allows easy integration with energy monitoring systems.

Field-configurable expansion modules can be fitted for enhanced functionality. 

Elite 440 can be configured by software or by push-buttons on the front panel.
