Product Overview:
HAT835S Three Power Bus Tie Controller is intelligent tri-supply module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking. Automatic measurement and control can reduce human error, which is an ideal option for three power transfer.

The powerful microprocessor contained within the unit allows for precision voltage (3-way 3-phase) measuring and make accurate judgment and the corresponding volt free digital output port will active when there is over/under voltage, over/under frequency, loss of phase, reverse phase sequence and other abnormal condition occurs. It has compact structure, advanced circuits, simple wiring and high reliability, and can be widely used in electrical automatic control system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, intelligent building, etc.

2. 4.3 inchs single color 240x128 LCD display with white backlight, multilingual interface (including English, Simplified Chinese or Traditional Chinese), push-button operation;

3. LCD can visually display current system topology, S1/S2/S3 voltage, frequency and other parameters;

4. Collect and display 3-way 3-phase voltage, frequency and phase sequence;

5. With over/under voltage, over/under frequency, loss of phase, reverse phase sequence detection function;

6. Single breaker operation and system parameters adjusting can be conducted via front panel key;

7. Display QS1/QS2/QS3/QTIE1/QTIE2 accumulated close times;

8. Display S1/S2/S3 accumulated supply time, current continuous power time, last continuous power time and accumulated power time of LOAD1/LOAD2/LOAD3;

9. For Stored-Energy type switch, its close relay will be active after the PF Input is active;

10. Auto/Manual mode transfer. In manual mode, it can force the switch to close or open;

11. All parameters can be set on site. Passwords authentication ensures authorized staff operation only;

12. The unit can be manually tested on site to achieve start/stop operation;

13. Closing output signal can be set as pulse or continuous output;

14. Applicable for 3 isolated neutral line;

15. With elevator delay output function;

16. Real-time clock (RTC); event log function (event log can record 200 items circularly);

17. Scheduled run & scheduled not run (can be set as start genset once a day/week/month whether with load or not);

18. Can control multiple gensets to work as cycle run mode, master run mode, balanced time run mode;

19. User can monitor data communication protocol address;

20. PLC function is fitted;

21. DIN16A-2 and DOUT16B-2 module can be connected via RS485 port;

22. With Dual-RS485 isolated communication port. With “remote control, remote measurement, remote communication, remote adjustment” function by the ModBus-RTU communication protocol. It can remotely start/stop the genset and control breaker close or open;

23. Widely DC power supply range allows the controller can bear instantaneous 80V DC input;

24. Large terminal space allows the controller can bear maximum 625V AC voltage input;

25. Suitable for various AC systems (3-phase 4-wire, 3-phase 3-wire, single-phase 2-wire, and 2-phase 3-wire);

26.Modular design, anti-flaming ABS plastic shell, pluggable terminal, built-in mounting, compact structure with easy installation.
