The Series PN500 Multi Function Digital Power Analyzer is an Advanced Three-Phase LCD Smart KWH Meter engineered for comprehensive power monitoring and management in diverse industrial and commercial applications. This robust device excels in accurately measuring a wide array of electrical parameters, including phase and line voltages, three-phase currents, active, reactive, and apparent power (both split-phase and total), power factor, and frequency.

Its capability for four-quadrant power metering, recording both forward / reverse active and positive/reverse reactive energy, makes it ideal for detailed energy analysis and billing.

Equipped with a clear segmented LCD display, the PN500 provides immediate and easily readable data. Its powerful data acquisition and processing functions allow for real-time insights into power consumption and quality. A key strength of the PN500 lies in its communication capabilities, featuring an RS485 interface and supporting the widely adopted Modbus-RTU protocol. This enables seamless integration into existing SCADA systems, energy management platforms, and building automation networks, facilitating remote monitoring, control, and data logging

• Provide a detailed overview of the electrical health and consumption patterns within a three-phase system, allowing users to identify anomalies, power factor issues, and unbalanced loads.
• By accurately measuring active and reactive energy in four quadrants, it supports detailed energy billing, cost allocation, and the implementation of energy-saving strategies.
• Through its RS485 and Modbus-RTU interface, it can be seamlessly integrated into a centralized monitoring system, allowing operators to remotely view real-time data, receive alarms, and potentially control loads (via the relay output).
• Its flexible input/output options allow it to interact with other equipment and systems, triggering alarms, controlling relays based on measured parameters, or feeding analog signals to PLCs or other controllers.

This series of digital LCD three-phase multi-function meter adopts professional metering chip with industrial-grade microprocessor as the core to measure electric parameters such as voltage, current, power, power factor, frequency, forward and reverse bi-directional electric energy in the power grid, which has high cost performance.

Embedded installation, simple wiring, small amount of engineering. Broken code liquid crystal display, easy to read the data. Widely used in electric power grid, automation control system, SCADA, DCS system, etc., help users save investment and use space
