ADL100-EY prepaid electric energy meter adopts din rail installation structure, mainly used for measuring single-phase AC active electric energy with rated frequency of 50Hz, with functions of prepayment, load control and RS485 communication, etc. Its performance indicators meet GB/ T18460.3-2001 standard. It is an ideal energy meter for reforming the traditional electricity system and improving the management level of electricity consumption.
| 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 | The meter will shut down the power once the credit balance is below zero. (Data like credit balance is saved in the meter) |
| Postpaid Mode | The meter won't shut down the power once the credit balance is below zero. (Can remotely control the meter to shut down the power by using Prepaid System) | |
| Mode Change | The meter can change the mode between prepaid and postpaid by receiving the command from the 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 the circuits breaker, also, this type of control will only be triggered when the meter is in Prepaid Mode |
| Remote Control | Remote control will be commanded by a prepaid system. When users give a command to switch on-off to a certain meter, this command will be sent to meters through wireless communication, and finally, the meter will shut down or recover the power after receiving the command. This type of control can be done when the 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 | 220~264Vac L-N (Voltage signal input will be also served as a power supply for meters) |
| Frequency | 45~65Hz | |
| Input Current | Rated Current | 10(60)A AC (via direct connect) |
| Starting Current | 0.004 Ib | |
| Accuracy | Measurement | Class 1 |
| Clock | ≤0.5s/d | |
| Pulse | Pulse Width | 80ms±20ms |
| Pulse Constant | 1600imp/kWh | |
| Communication | RS485 Interface | MODBUS-RTU Protocol |
| Infrared | Used for Meter Reading | |
| HMI | LCD Display | 8 bits section LCD display |
| Keypads Programming | The setting of communication, current ratio and etc. | |
| Mechanical Feature | Outline Dimension(L*W*H) | 72mm*88mm*70mm |
| Max Wiring Ability (with Flexible Cable) | 25mm2 | |
| Environment | Operating Temperature | -25℃~+55℃ |
| Storage Temperature | -40℃~+70℃ | |
| Humidity | ≤95% (No condensation) | |
| Altitude | ＜2000m | |
RS-485 interface can be configured to meet ModBUS-RTU protocol communication, and 1200/2400/4800/9600/19200/38400 baud rates can be configured;
In an emergency, the power protection function can be turned on to keep the power consumption normal, and the remote buttons can be set;
The maximum power consumption of the branch can be limited. When the power of the branch exceeds the set value, the branch will trip.
