 DC/AC multifunction meter

Description  

Multifunction Electric Power Meter integrate the functions with programmable measurement, display, digital communication and electric energy impulse transmitting output, which can carry out electric power measurement, electric energy calculation, data display, data acquisition and data transmission. They are widely used transform substation automation, Distribution network automation, intelligent construction and the inner electric energy measurement, management and evaluation in the enterprise. The meters is class 0.5, achieved LED/LCD display on spot, RS485 digital interface communication remote control, adopt MODBUS-RUT communication protocol.
