ADL300-EY three phase pre-paid meters with intro-control are used for calculating the active energy respectively on the frequency of 50/60 Hz. The built-in magnetic of meter can keep the relay on and off .It also supports RF card and remote recharge, load controlling and RS485 communication etc. meet the related technical requirements of electronic power meter in the IEC62053-21, IEC62053-22 standards.
Technical Parameters
| Parameter | Description&Value | |
| Measurement | kWh&kVarh | Total active kWh (bidirectional --positive and negative in total) |
| 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 |
| 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 | |
