Product Description Chapter 1. General introductionThe 3U(3I) combined meter is used to measure and display the direct digital reading of voltage/current value in the three-phase electrical line. The UIF combined meter is used to measure and display the direct digital reading of voltage, current, and frequency values in the single-phase electrical line. One meter can finish the measuring tasks of three common meters. It can support the analog output, alarm, and RS4485 communication function by the installation of different functional modules. And it can also select the multiple functional modules at the same time to make it with the alarm, transmitting, and communication functions.Chapter 2.General parametersChapter 3.General parameters Input specification of the voltageAC 100V,220V,380V or 500V (external PT is necessary if more than 500V) Input specification of currentAC 1A or (external CT is necessary if more than 5A) Frequency of input signal45~65HzAccuracy gradeclass 0.5Alarm outputrelay contact output,contact capacity AC 250V/1A;DC 30V/1A,resistive loadCommunication interfaceRS485 serial communication, MODBUS-RTU communication protocolTransmitting outputlinearity 0.5%, load resistance: output current≤300Ω, output voltage≥1KΩ, which are electrically isolated with the input signal and the auxiliary power supply Switch inputdry contact input Photos of Product
