Prepaid Multi-User Smart Meter with Card Swipe

Prepaid Card Swipe Multi-User Electricity Meter Product Overview

The inductive multi-user electricity meter integrates card reading/writing and control modules based on the multi-user electricity meter. It uses a single-chip microcomputer as the processor, enabling centralized monitoring and individual control for up to 36 single-phase users. It cyclically displays the remaining electricity information for each household. Equipped with Class 2 precision current and voltage transformers, it offers a wide measurement range, accurate metering, and a compact design. Each household uses one card; placing the card parallel to the meter's induction area enables reading and writing of electricity data.

Product Features

1. One card per household; electricity must be purchased before use, facilitating electricity management.

2. Features calibration input and output terminals for easy on-site meter verification.

3. Each household can be reset individually, making it convenient for management departments to handle changes in users.

4. Simply place the card parallel to the meter's induction area to read and write electricity data.

5. Uses high-frequency M1 RF cards for highly stable data transmission and contactless operation.

6. Employs voltage and current transformers as electrical signal sensing components for effective performance.

7. Prepaid functionality, individual metering and control, high accuracy, stable performance, and long service life.

8. Utilizes high-capacity magnetic latching relays, resulting in low overall power consumption, strong overcurrent capability, and stable long-term operation.

9. When a user's remaining electricity reaches the power-off alarm value, the household's power is cut off. The user can then place the card near the meter's induction area to automatically restore power until the electricity runs out, at which point power is cut off again. Electricity can only be resumed after purchasing and swiping the card.
