Single Phase Electronic Energy Meter(digital meter

General Introduction DDSJ318 Single phase electronic energy meter is designed for measuring active energy in single phase alternating current power. The meter has the feature of high accuracy, high overload capacity, low power consumption, small size, light weight, long life and wide working voltage. This type of meter not only has the function of measuring power, but also has the function of tamper-proof Standards IEC62053-21/IEC62052-11 Specifications Type: DDSJ318 Accuracy class: 1.0 Consumption in voltage circuit: ≤ 1 W/10 VA Consumption in current circuit: ≤ 1 VA Rated voltage: 220V, 230V, 240V Rated current: 5 (30)A, 10 (60)A, 5 (40)A, 15 (60)A, 20(100)A Rated frequency: 50/60Hz Display type: LCD Main Functions l Measure single phase AC energy l LCD showing the total consumed energy l Register energy only forward even under reverse connection condition l With impulse output interface for direct calibration of the meter's accuracy l 3200imp/kWh indicator showing impulse constant l GND indicator showing tamper of earth loading l REV indicator showing tamper of reverse connection l Long terminal cover to prevent tampering
