Basic function                                                        
Metering function:Measuring, settlement date archived, instantaneous, conventions, timing, the combination of day freeze, forward, reverse, total active energy, active energy of each rate, four quadrant, combination of reactive power, demand, power and other important data.Time: Calendar, timing, and switch of non-leap year & leap year, two sets of rate, period conversion, broadcasting time setting function. Event log:Event log of (A, B, C three-phase), overvoltage, undervoltage, phase failure, current loss, current break, over current, reverse power, overload, etc.Display and keys: LCD automatic cycle and key cycle display programming setting data items.
5. Alarm function, as for the loss of pressure, the inverse phase sequence, overload, battery under voltage, etc., watt-hour meter can use backlight alarm and alarm output outside terminal to connect alarm device to give an alarm, and can be turn off by a button.
11. Communication function:Positive and reverse connection of RS485 bus can both communicate normally, infrared communication shall make safety certification before successful operation, only passed the certification can operate meters, support PLC, RF, WIFI, GPRS communication modules etc.

Application range
It is applied for customers of specialty transformers100KVA or higher, area total meter and gate meter.
