Multifunction Meter 1010

Multifunction Meter 1010

Multifunction meter is specifically designed and made for the electrical monitoring requirement of power distribution system. Multifunction meter ( MFM ) is with high-precision measurement all of the common electrical parameters including of three-phase voltage, three-phase current,active power, reactive power, frequency, power factor and four-quadrant energy etc; Long-life LED display the instrument measuring parameters and operation information of network system; RS485 communication interface, applying MODBUS RTU communication protocol; with four programmable keys on the instrument panel, convenient switch, programmable setting of instrument parameters with great flexibility

Many kinds of extended function modules for choosing: four-channel analog quantity (0 -20mA/4-20mA) output can realize the transmitting output function of electrical quantity; four-channel switching value input and four-channel switching value output to realize the local or long-range switch signal monitoring and control output function (function of “remote signaling” and “remote control”) .

Multifunction meter is widely used in occasions of energy management systems, supply and distribution network automation, district power control and complete sets of switchgear. It has the advantages of convenient installation and maintenance, sample wiring, small quantity, programmable input parameters and capable of the network with different PLC, industry control computer communications software
