EI900 series are three phase multifunctional power analyzer to measure and analyze most important electrical parameters, including voltage, current, four-quadrant power parameters, power factor, total harmonic and fractional harmonic content, imbalance, crest factor, and etc. And it can also read a variety of energy parameters, involving bidirectional active and reactive energy, four-quadrant energy, monthly and daily energy consumption statistics, and so on. The series realizes the measurement and analysis of power parameters in various power grid environments, such as 1P2W, 2P3W, 3P3W and 3P4W, providing multi-channel digital input and output interfaces and 30 SOE records.
The EI900 series are external voltage transformer (PT) and current transformer (CT) input. The Max. current input is 9999A, and voltage input 600kV. The products have RS485 communication interface with highest baudrate 38400bps, Modbus or DLT645, to make it read remotely.
At the same time, the large-screen LCD and touch buttons help users to view and set various measurement parameters on site.
Password protection function is added to greatly improve the data security.
