1. Product overview

The CG2000E is specifically designed for the comprehensive collection of electrical parameters in 50/60Hz power supply systems. It can measure and display three-phase current, three-phase voltage, active power, and electrical energy (kWh). (The electrical energy values are solely for internal secondary metering, assessment, and accounting within the enterprise and are not to be used for pricing, measurement, or payment purposes.)

2. Functions & features

· Multi-function integrated

Integrating ammeter, voltmeter, wattmeter, and energy meter into one unit

It features intelligent integrated circuit design with the function of True Root Mean Square (Trms) measurement for voltage and current, ensuring accurate measurement and display even when voltage and current waveforms are distorted.

By setting the CT ratio on the panel, the primary operating current of the power distribution system can be displayed intuitively, which is suitable for power distribution systems with three-phase three-wire connection or three-phase four-wire connection.

· Smart interconnection

Full digital display

RS485 serial interface, ModBus protocol, selectable communication baud rate: 4800 or 9600.
