Product Overview
The YD6600 Series energy meter is designed to monitor three-phase AC electrical systems accurately. It supports measurement of voltage, current, active/reactive/apparent power, power factor, frequency, total energy (kWh/kVarh), as well as other electrical parameters. With support for RS-485 Modbus RTU communication, this meter can be integrated into SCADA, EMS, or BMS platforms for centralized monitoring and control.
Constructed for industrial environments, the YD6600 features durable build quality, stable performance in wide temperature and humidity ranges, and multiple mounting options (panel / rail). It is suitable for factories, distribution panels, energy audits, and smart buildings.
