The PowerTag Energy R2000 3P/3P+N is an energy meter with wireless communication. With its Rogowski current transformers, it is suitable for 3P and 3P+N measurement points with a nominal current of up to 2000 A. It must be connected to an Ethernet gateway (Modbus TCP) for wireless energy meters to enable measurement, circuit monitoring, and load diagnostics. It is specifically designed for applications in energy management, load monitoring, and availability. It includes accurate real-time measurements of active, reactive, and apparent energy, active, reactive, and apparent power, current, voltage, and power factor. In the event of a power failure, it sends a voltage loss alarm and the current value per phase before shutting down. The PowerTag Energy R2000 complies with the IEC 61557-12 standard. It is a PMD-II/DD/K70/1. The accuracy class is Class 1. The maximum current Imax is 2000 A. The Ib base current is 300 A. The saturation current is 4000 A, and the start current is 1200 mA. The rated voltages are phase-neutral 100 to 277 VAC +/- 20% and phase-phase 173 to 480 VAC +/- 20%. The maximum consumption is under 3 VA. The current transformers can be mounted on either bare or insulated busbars or on cables. The product color is white (RAL 9003). The weight is 360 g. The protection degree is IP20 (IP40 front side) and IK08. The operating temperature ranges from -25 °C to +70 °C. The storage temperature ranges from -40 °C to +85 °C.
