| Local&Online Topping Up ● Topping up by RFID Card (Local) ● Topping up by Mobile APP (Online) ● Topping up by Prepaid System (Online) ● Low Balance Credit Alarm by sending SMS |
| Multi-rate&Multi-tariff ● 4 Tariff Rates (Spike, Peak, Flat, Valley kWh Unit Price) ● 14 Time Intervals by Day ● Set Unit Price of Electricity Consumption for different Time Periods of 1 Day |
Parameter | Description&Value | |
Measurement | kWh&kVarh | Total active kWh (bidirectional --positive and negative in total) |
Electrical Parameters | 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 realize on-off control of circuits breaker, also, this type of control will only be triggered when meter is in Prepaid Mode |
Remote Control | Remote control will be commanded by prepaid system. When users give the 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 |
