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: 106 KBPS; Sensing distance: ≤ 10 cm

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

B. Functional Features

1. Tiered water pricing – Supports three-level, four-tier progressive pricing (water + electricity), meeting agricultural water pricing reform requirements for cumulative pricing.

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

3. Multi-card & multi-well support – One well with multiple cards, one card for multiple wells, or dedicated well‑specific cards (requires JTG60-8 management unit software for configuration).

4. Tap-to-start/stop – Simply tap the RF card to start or stop the pump; the system automatically meters and deducts charges based on preset pricing.

5. Comprehensive protection – Includes motor phase-loss protection, overload protection, and short-circuit protection.

6. Electricity-to-water conversion – Optional function calculates and displays water consumption based on electricity usage using a preset water‑electricity coefficient, eliminating the need for a separate flow meter.

7. LCD display – Shows total water consumption, total water charges, total electricity consumption, total electricity charges, and water quota percentage.

8. Low balance alert – Configurable early warning threshold to help users manage usage and recharge in time without service interruption.

9. Intelligent authentication – Automatically identifies and rejects unauthorized or counterfeit cards, preventing management loopholes.

10. History & loss prevention – Supports lost card balance inquiry, replacement card issuance, and cancellation of lost cards to prevent unauthorized use.

11. Unsettled card reminder – Displays an alert for any unsettled card left from the previous session, facilitating management for both users and administrators.

12. Misoperation prevention – Requires a second card tap to start pumping. This prevents accidental pump startup when a user simply checks their balance (without intending to irrigate), avoiding pipe damage or wasted water/electricity.

13. Balance inquiry during operation – Allows other users to tap their cards to check balances without interrupting the current user's irrigation session.

14. Auto power‑saving mode – Automatically enters sleep mode when left idle to conserve energy.

15. Tamper/theft protection – Detects electricity or water theft (meter bypassing) and automatically cuts off the high‑voltage supply. (Note: Requires installation of a high‑voltage synchronous power management box.)

16. Remote data transmission – Supports real‑time remote transmission of user water data and well extraction data (requires optional communication module).

17. Local & remote control – Supports local operation; optional communication module enables remote ON/OFF control via mobile APP or PC.

18. Remote parameter setting – Supports remote configuration of water quotas, pricing, and other parameters (requires optional communication module).

19. Sequential user access – Only one user can operate at a time; other users are queued and cannot interrupt an active session.

20. Sealed ABS enclosure – Provides protection against water splashes, dust, and insects, ensuring reliable performance in outdoor field conditions.
