Acrel ADL400 din-rail multifunctional energy meter is an intelligent instrument designed mainly for electric energy statistics and management needs of power systems, industrial and mining enterprises, and public facilities. The product has the advantages of high precision, small size, and convenient installation. It can integrate power parameter measurement and power metering and assessment management, and provide various power data statistics for the last 48 months. It has 2~31 sub-harmonic and total harmonic content detection. With RS485 communication interface, MODBUS-RTU or DL/T645 protocol can be selected. The energy meter can be widely used in various control systems, SCADA systems and energy management systems.
