Multi Function Meter 3400

Multi Function Meter 3400

Multi function Meter 3400 is a latest product in the SANDS Energy Management Solutions. For any Industry irrespective of their domain, the need of the hour is Energy Management System. One has to know what is the Energy that each one of the various departments consume daily/montly. To do this, we dont need a full blown Energy meter rather a cheap but feature rich Multifunction meter should suffice. MFM 3400 is one such meter that measures all the necessary electrical parameters for energy management system like Power, Power factor, Energy Import, Energy Export etc at 0.5S accuracy. Using Industry standard Modbus RTU protocol, any DCU can collect the parameters list from the MFM 3400 through RS485 interface
