Bypass ATSE Control Module--HAT880

Bypass ATSE Control Module--HAT880

According to GB 50174-2008 "Design specification for computer room of electronic information system”and 09 DX009 “Engineering design and installation for computer room of electronic information system”national standard atlas and other relevant regulations and requirements, having a high request for power system reliability, continuity of the special important places. In order to prevent when ATS failure, damage or automatic transfer switch is in maintenance, affecting the continuity of the power supply system, we should set bypass isolation type ATS. In addition, the switch between mains and diesel generator shall adopt the automatic switch with bypass function, which shall not affect the switch of power supply when the automatic switch is repaired.

According to the application of bypass ATSE, SmartGen has designed and developed a bypass ATSE control module--HAT880, the main functions are as follows:
  1. System type can be set

  2. 4.3 inches LCD display with Chinese & English

  3. Display position of main switch (working, testing, insulated)

  4. Display position of bypass switch (working, testing, insulated)

  5. Collect and display voltage, frequency and phase sequence of 2-way-3 

  6. Independent S1/S2 over current warning or trip alarm functions

  7. NEL (Non-Essential Load) trip functions

  8. Display S1/S2 total kW energy, total Kvar engergy

  9. Display continuous power supply time at present and last time, and S1/S2 total power supply time

  10. For energy-accumulated ATS, it shall close when switch PF (close is prepared well )signal is active

  11. Over/under voltage, over/under frequency, over current, loss of phase,  inverse phase sequence protection functions

  12. Automatic/Manual mode swichover; In manual mode, close or open can be controlled manually

  13. The genset can be tested maually on site to achieve start/stop operation

  14. Re-close function of main switch and bypass switch in auto mode when power outage occurs

  15. Applicable for single bypass, doubel bypass and alternate dual spare bypass switch

  16. Applicable for bypass switch of manual control and remote control

  17. Real-time clock (RTC);even log function, which can record  a 200 items circularly

  18. Black box record function, which can record 5 events circularly,60 data of 50s before each event record and 10s after each event record

  19. Scheduled routing start& scheduled not start function for the genset, which can be set a start once a day/week/month; and running with load or not

  20. Can control two generators to work in the mode of circular running, master running and balanced running

  21. Wide DC power supply range, which allows the control module to bear instantaneous 80V DC current input

  22. Large terminal space allows the control module to bear maximum 625V AC voltage input

  23. Dual isolated RS485 communication interface, having the functions of “remote control,  remote measuring, remote communication, remote regulating” by the ModBus-RTU communication protocal, which can remotely start/stop the genset and control  the breaker to  close or open

  24. DC8.0V~35V, continuous power supply

  25. AC (90~305)V power supply A1N1/A2N2
