A. Technical Specifications

1. Operating voltage: 380V ± 10%

2. Applicable pump power: ≤ 11KW

3. RF card: Compliant with ISO/IEC14443A protocol, 32-bit unique serial number

4. Operating frequency: 13.56MHz; Communication rate: 106KBPS; Sensing distance: ≤ 10cm

5. Unit price setting accurate to two decimal places (0.00 currency units)

6. Chinese character LCD display; Maximum recharge display: 8 digits (999999.99)

B. Functional Features

1. Tiered water pricing – Supports three-tier, four-step water pricing plus electricity pricing, with progressive cumulative pricing to meet agricultural water pricing reform requirements.

2. Flexible metering configuration – Supports water-only, electricity-only, dual metering, single control, dual control, single pricing, and tiered water pricing modes, configurable to meet diverse metering and control requirements.

3. One well, one card – Dedicated card for each well. The controller writes the card balance upon first use. The controller remains powered as long as the card has a remaining balance.

4. Auto power-on – With a valid card balance, the controller automatically closes the circuit and starts the pump. Billing and fee deduction begin automatically upon pump startup.

5. Loss/cancellation replacement – Allows cancellation of lost or stolen cards. A new card becomes the dedicated card upon first use, rendering the old card invalid.

6. Balance inquiry – When the controller is powered, the remaining balance is displayed on the LCD screen.

7. Comprehensive protection – Built-in motor phase-loss protection, overload protection, and short-circuit protection.

8. Electricity-to-water conversion – Based on user-set coefficients, electricity consumption can be converted to and displayed as water volume, eliminating the need for a separate flow meter.

9. LCD display – Shows total water usage, total water cost, total electricity usage, total electricity cost, and water quota percentage.

10. Low balance alert – Configurable alert threshold to help users monitor usage and recharge in time.

11. Intelligent card recognition – Automatically identifies illegal or counterfeit cards, preventing management loopholes.

12. Auto sleep mode – Enters sleep mode to save energy if the user forgets to power off.

13. Anti-theft protection – Detects electricity theft or water bypassing and automatically cuts off the power supply. (Note: Requires installation of a high-potential power synchronous management box.)

14. Remote data transmission (with optional communication module) – Supports real-time transmission of water usage data from users and well extraction data.

15. Local & remote control (with optional communication module) – Supports both local operation and remote ON/OFF commands via mobile app or PC.

16. Remote parameter setting (with optional communication module) – Allows remote configuration of water quotas, pricing, and other parameters.

17. Sealed ABS enclosure – Water-splash proof, dustproof, and insect-proof, suitable for outdoor field environments.
