DTSD876 / DSSD876 0.2S Three Phase Multi-Function En

General DTSD876/DSSD876 0.2S Three Phase Multi-Function Energy Meter is a high accuracy, good stability, high overload ability and reliability grid meter. It measures active and reactive energy, harmonic and fundamental wave. it's an advanced andreliable measuring product for power sector and is wildly used in power plant and transformers. It conforms with the requirements of IEC 62052-11,21, IEC 62052-21, IEC 62053-22, IEC 62053-23 and IEC 62056-21. Main Features Measurement storage of forward/reverse active, reactive energy and reactive four quadrants for latest three months Record Max. demand of active/reactive, forward/reverse with its start time and duration for latest three months Measures real time voltage, current ,power, power factor, and frequency etc. 4 seasons, 4 tariffs,12 time intervals, 12 holidays Awaken by infrared or button. Read by infrared while power outage Events log: loss of voltage, loss of current, phase failure, power outage/recover, over current, over voltage, data freeze, programming, demand reset , cover open and etc. Load profile, memory capacity available from 64K to 256K Energy freeze: Freeze energy data at real time, at 24:00 or at time zone shift Harmonic wave measurement, fundamental wave measurement Two independent RS485 communication interfaces and one infrared interface Various testing signal output LCD display Measures current when all phase failures (Optional)
