Prepaid multi-user energy meter

1、 Product Introduction

1Prepaid multi-user energy meterCan accurately measure active energy in both positive and negative directions to prevent electricity theft.

2. Clearly display the electricity consumption information of each user through a digital tube, and cyclically display the remaining power of each household every four seconds. The upper digital display shows the user ID, while the lower digital display shows the current remaining battery level of the user.

3. It has the function of infrared reading of remaining electricity, which can read the remaining electricity of users on site and import it into the electricity sales management system for statistical analysis.

4. Wide range of 10 (50) A, using magnetic holding relay, with strong overcurrent capability, suitable for users with large load changes.

5. According to user needs, single-phase and three-phase can be combined for household use. Single phase can control up to 39 households, while three-phase can control up to 13 households. The wiring is simple and the operation is convenient.

6. The whole machine has low power consumption (<6V A) and significant energy-saving effect. Specialized anti creep and watchdog circuits make operation more reliable.

7. It has a power outage alarm flashing prompt. When the power outage alarm is reached, the meter will automatically power off. If the user continues to use the remaining power in the meter, they need to swipe their card once to continue using it.

8. RF cards have the characteristics of contactless, moisture-proof, anti attack, good encryption, stable data transmission, and long service life. The data in the RF card can be stored for more than 20 years, and it adopts encrypted control logic and communication circuits for higher reliability.

9. This machine has a relay demagnetization function to prevent demagnetization. Every 8-15 minutes, all relays should be demagnetized once. If the user swipes their card during the demagnetization, the relay may not operate completely. When demagnetized again, the relay will be normal.

4、 Purpose and Scope of Application

Under normal use, the digital tube of a multi-user energy meter displays the meter number, sales software unit number, user number, and total remaining power in a loop. When the power outage alarm is reached or the remaining power is zero, the relay is disconnected, and the digital tube in the lower row flashes to display -00000 per household, prompting the user to purchase electricity and recharge in a timely manner. When recharging and swiping a card, the electricity meter first displays the user's current purchase amount, and then displays the user's accumulated remaining amount. If the power outage alarm is reached, the remaining power in the meter can continue to be used, and the user needs to swipe their card again to continue using the remaining power in the meter.
