Technical Parameter

Parameter	Description&Value
Measurement	kWh&kVarh	Total active kWh (bidirectional --positive and negative in total)
Measurement		Electrical Paratmeters	U (Voltage), I (Current), P (Active Power), Q (Reactive Power),S (Apparent Power), PF (Power Factor), F (Frequency)
Function Mode	Prepaid Mode	Meter will shut down the power once the credit balance is below zero. (Data like credit balance is saved in the meter)
		Postpaid Mode	Meter won't shut down the power once credit balance is below zero. (Can remotely control the meter to shut down the power by using Prepaid System)
		Mode Change	Meter can change the mode between prepaid and postpaid by receiving the command from prepaid system
Control	Auto-tripping Control	Auto-tripping control is processed by the built-in high-capacity holding relay of the meters to realized on-off control of circuits breaker, also, this type of control will only be triggerred when meter is in Prepaid Mode
Control		Remote Control	Remote control will be command by prepaid system. When users give a command of switch on-off to a certain meter, this command will be send to meters through wireless communication and finally meter will shut down or recover the power after receiving the command. This type of control can be done when meter is in Postpaid Mode
Multi-rate Multi-Tariff	Optional Function	4 tariff rates (spike, peak, valley, flat); 14 time intervals by day
Input Voltage	Rated Voltage	3x380~456Vac L-L (Voltage signal input will be also served as power supply for meters)
