Din Rail-type Energy Meter
DDZYU2367
Overview
The DDZYU2367 Single-phase Double-circuit Tariff Control Energy Meter is specially developed for power consumption management of student dormitories, and adopts standard 4P module and LCD. This product not only has the electric energy measurement and electrical parameter monitoring functions of traditional electric meters, but also has safe electricity use management functions for student dormitories such as timed ON/OFF, overload identification, malignant load identification, and time-share current limiting.

Functional characteristics
♦ Electric energy measurement, with a measurement accuracy of class 1.0.
♦ Remote pre-payment, automatic switch-off in case of insufficient balance, automatic power restoration after recharging.
♦ Built-in system clock, realizing timed power ON/OFF function.
♦ Overload identification, time-share current limiting, allowing setting different overload thresholds for different time periods.
♦ Malignant load identification, effectively identifying illegal high-power electrical appliances and pure resistive loads.
♦ Have the anti-blackout socket identification function, thus effectively controlling the use of prohibited electrical appliances.
♦ Have the function of detecting the operating temperature of electric meter, so that the power supply will be cut off automatically when the temperature exceeds the set value.
♦ Have automatic power restoration function, so that the power supply can be restored after overload power outage or power outage due to use of malignant load. The time of power restoration and the number of tripping times can be set.
♦ Real-time monitoring of parameters such as voltage, current, power, and power factor.
♦ Independent CPU, independent metering unit, independent storage unit, local parameter configuration, which can run completely independently.
