The Power Instruments Three-Phase Current & Voltage Combination Meter is an all-in-one digital device designed for simultaneous real-time monitoring of phase currents and voltages in industrial power distribution systems. Utilizing advanced AC sampling and True RMS technology, it delivers highly accurate readings even under harmonic distortion. The meter features a multi-row LED/LCD display and supports front-panel programming for CT/PT ratio configuration. With optional RS485 communication via the Modbus-RTU protocol, it integrates seamlessly into energy management and automation systems. Ideal for factories, commercial buildings, and substations, it consolidates multiple metering functions into a single unit to save panel space and reduce wiring costs.
