Digital Three-phase Multi-Function Voltage Current Meter Voltmeter Ammeter Smart Instrument

Features:

Digital three-phase ammeter & voltmeter is a kind of smart instrument which can program measurement , display, alarm, digital communications and analog quantity output, widely used in substation automation, electrical automation, intelligent buildings, machinery, equipment, etc. True RMS measure, high precision, good stability.The instrument transformer ratio can be set by button, convenient and flexible for use. Three rows of four-digit highlighted red Lro shows three phase current or voltage value directly. Optional 1 or 2 channel relay alarm output, to realize upper and lower limit alarm function; Optional RS-485 digital communication interface, it uses international standard MODBUS-RTU communication protocol, can realize network with a variety of PLC, HMI, configuration software. Optional 1 or 3 channel analog quantity (DC0~20mA, DC4~20mA, DC0~5V, DC1~5V, DC0~10V, etc.) analog output, analog quantity output is isolated with input signal, which has a linear corresponding relation.
