Basic Functions of Smart Remote Prepaid Electricity Meter

The remote prepaid energy meter has the following basic functions:

1-hour active power forward and reverse energy metering can be divided into 4 tariffs, 12 time periods, and 2 time zones.

2. With the ladder function, 4 ladders can be set, and the electricity and electricity price of each ladder can be set separately.

3. Infrared communication, programming, and meter reading can be completed through a handheld computer.

4. Rotary display of parameters can be realized. The parameters (not more than 32 items) and the time interval of the display can be set in advance, and the sequence of the display of parameters can also be set arbitrarily.

5. Active and passive pulse output interface with optocoupler isolation, the pulse constant is the same as the meter constant.

6 Record the total active power and time-sharing power for 12 months and can read the meter through infrared or 485.

7. It has the function of programming prohibition and data clearing.

8 Abbreviated meter reading in support of Ministry Statutes.

9. It has the ability to purchase electricity first and then use it, and automatically freeze the electricity consumption at each rate every month on the designated meter reading day.

10. The IC card can be used for parameter setting and meter reading.

11. Adopting the method of one meter and one card, the data in the IC card is multi-checked and encrypted, which is safe and reliable.

12 Each time the electricity is purchased, data is transmitted bi-directionally through the electricity card.

13 Can set non-working hours and emergency credit limit.

14 The maximum power used can be limited within the rated current range (limited by the power supply department).

15 has an external alarm output interface.

16 with built-in sound and light alarm, tripping and power-off function

a. When overloaded, alarm and trip signal output can be controlled by selecting whether alarm tripping is allowed.

b. When the remaining power is less than or equal to the alarm setting value, the meter can control whether the alarm and trip signal are output or not by selecting whether the alarm and trip are allowed.

c. When the remaining power is equal to zero, the meter outputs a trip signal.
