FU2000 Multifunction electrical digital power meter

electric three phase power meter

FU2000 digital power meter is a multifunction electrical digital power & energy meter, it can measure all the electrical parameters in the power line, and it has RTC, calendar and one pulse output, one RS485, with modbus RTU communication. As an advanced smart and digital front end data sampling unit, the FU2000 electrical digital power meters can be used in various control system, industrial automation, smart buildings, energy management system, substation automation, residential power monitoring, smart distributor and switch gears. They are easy to install, connect, maintain. They need less project cost and field programming on spot for power grid grouping with different PLC and industrial control PC communication software.
