ADL200 single-phase electronic watt-hour meter is mainly used to measure single-phase active energy in low-voltage networks. It can also measure voltage, current, power and other electricity. It can also be equipped with RS485 communication function to facilitate users to monitor, collect and manage electricity consumption. It can be flexibly installed in the distribution box to realize the sub-item electric energy measurement, statistics and analysis of different areas and different loads. The product meets the requirements of the national standard GB/T17215.321-2008 and the enterprise standard Q31/0114000129C035-2017 "Enterprise Standard for Rail Mounted Electric Energy Meters".
