Single Phase Multifunctional Power Instrument

Multifunctional power instrument (instrument for short below) is specifically designed and made for the electrical monitoring requirement of power distribution system. It is with high-precision measurement all of the common electrical parameters including of single-phase voltage, current, active power, reactive power, frequency, power factor and energy ect; Long-life LED display the instrument measuring parameters ; 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.

    Product Overview

    Many kinds of extended function modules for choosing: one-channel analog quantity (0~20mA/4~20mA)output can realize the transmitting output function of electrical quantity; two-channel switching value input and two-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” ).The instrument can directly replace conventional power transmitter, measuring indicating instrument, electric energy measuring instrument and the related auxiliary unit. With modular structural design, users can choose the most economical functional configuration according to the actual requirement, which is highly cost-effective.
