1. Embedded high-speed and high-precision AC voltage and current acquisition module, high sampling accuracy, real-time accurate energy measurement.
2. In the case of losing AC power, the electric energy meter can keep the data and keep the clock chip working; low power consumption.
3. It can measure combined active power, positive and negative active power and demand, combined reactive power, four-quadrant reactive power, and have 485 communication, infrared communication and other functions.
4. Excellent electromagnetic compatibility, can resist the interference of high-voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and has a strong range of temperature adaptive capabilities.
5. Three-phase power supply (ie line power supply), when any phase of the three-phase three-wire or any two-phase of the three-phase four-wire is powered off, the electric energy meter can still work normally.
6. The power supply of the electric energy meter adopts two power supply modes: line and auxiliary power supply (AC/DC adaptive). The two power supply modes should be independent of each other and not affect each other; they can be automatically converted without interruption, and the auxiliary power supply mode is preferred.
