ADL400W Dreiphasiger CT-DIN-Schienen-Energiezähler mit integrierter Wi-Fi-Kommunikation

ADL400W Three-phase CT-DIN rail energy meter with integrated Wi-Fi communication

The ADL200W-ADL400W series DIN-rail-mounted, multifunctional dual-circuit electricity meter with external current transformer is a smart instrument primarily designed for new energy generation systems such as grid-connected photovoltaic systems, microinverter systems, energy storage systems, and AC coupling systems. The product offers the advantages of high precision, small size, high response speed, and easy installation. It can monitor and measure power and other performance parameters in real time, supports protocols such as Modbus-TCP and HTTP, and communicates with inverters or energy management systems (EMS) via Wi-Fi or Lora to achieve functions such as backflow prevention, power generation regulation, and battery charging and discharging. It enables bidirectional measurements to enable energy management for distributed photovoltaic systems in homes.
