Product Overview:

HMAT821 Series Medium Voltage Bus Tie ATS Controller is a module that integrates configurable function, automatic measurement, PT break detection, LCD display and digital communication. It combines digitization, intelligence and networking, the automatic measurement and control process can reduce incorrect operation, which is an ideal option for medium voltage bus-tie transfer.

HMAT821 Series Medium Voltage Bus Tie ATS Controller is composed of microprocessor as the core, which can precisely detect 2-way 3-phase incoming voltage, make accurate judgment for voltage abnormal situations (over/under voltage, over/under frequency, loss of phase, reverse phase sequence) and output passive control coil. With compact structure, advanced circuits, simple wiring and high reliability, it can be widely used in electrical automatic control system of electric power, telecom, petrochemical industry, mining, railways, municipal administration, data center, intelligent building and other industries.

PERFORMANCE AND CHARACTERISTICS

1. System type can be set as: Mains - Mains, Mains - Gen, Gen - Mains;

2. 4.3-inch single color 240x128 LCD display with white backlight, multilingual display (including Simplified Chinese, English and others), push-button operation;

3. Collect and display 2-way 3-phase voltage, current, phase sequence, frequency and voltage imbalance;

4. Display 2-way active power, reactive power, apparent power, power factor and earth current;

5. PT break detection function, whether PT wire is broken can be judged by measured voltage and current data, or PT break status can be obtained by digital input ports;

6. Display S1/S2 total power supply time;

7. Current duration and total duration of power supply for Load 1& Load 2;

8. Display total close times of QS1, QS2 and QTIE;

9. Detection functions of over/under voltage, over/under frequency, loss of phase, reverse phase sequence;

10. Earth fault protection function;

11. S1/S2 overcurrent warning or trip individual alarm function;

12. NEL trip function;

13. Manual commissioning to achieve genset start/stop operation;

14. Scheduled routing run & scheduled not run (can be set as genset start daily/weekly/monthly whether with load or not);

15. Real-time clock (RTC);

16. Event log function (event log can record 200 items circularly);

17. With black box function, can record 5 events circularly, 60 detailed data of 50s before each event record, and 10s after each event record;

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

19. Simultaneously control the closing and opening of the 2-way CB switch and the bus-tie CB switch to simplify the control system;

20. For stored-energy type ATS, its can close after the PF input is active;

21. Auto/Manual transfer, manually control the switch close or open in manual mode;

22. Local mode. When it is active, controller only displays data parameters, switch transfer needs to be realized by external operation;

23. Electric interlock release function, which is used for releasing electric interlock in switch parallel transfer (only suits for HMAT821S);

24. 6 kinds of buttons on the panel to manually control switch easily;

25. Breaker re-closing function;

26. Closing output signal can be set as pulse or continuous output, which is suitable for CB breaker or CC contactor;

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

28. 2-way N-wire isolated design;

29. Wide DC power supply range allows the controller can bear instantaneous 80V DC input;

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

31. With Dual-RS485 isolated communication interface. With "remote control, remote communication, remote measurement, remote adjusting" functions by the ModBus-RTU Communication protocol. Genset start/stop and ATS close/open can be controlled remotely;

32. USB is convenient to debug parameters and upgrade program locally;

33. Modular design, self extinguishing ABS shell, silicone panel, pluggable terminal, built-in mounting, compact structure with easy installation.
