00 HAT520NSuitable for NO Breaking ATS.-Smartgen,Genset Controller,Generator Controller,ATS Controller,panel manufactory,ats manufaction,battery charger manufactory 


The powerful Microprocessor contained within the HAT520N ATS controller allows for precision voltage (2-way 3-phase/single phase) measuring and make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong) and control ATS to transfer after the delay has expired. This controller is suitable for NO Breaking ATS. When 1# power is abnormal, the controller will send signal to start genset after the “1# abnormal delay” has expired. “Three remote” (remote control, remote measurement and remote communication) function can be implemented with the help of LINK communication port.

Product Feedback

HAT520N Dual Power ATS Controller is made by the core of the microprocessor, which can precisely detect 2-way 3-phase voltages, 2-way single phase voltages and make accurate judgment for the occurred abnormal voltages (lost of power, over voltage, under voltage, over frequency, under frequency, loss of phase, phase sequence wrong), controlling ATS switchover after delay. It is suitable for controlling No Breaking ATS, and it has the function of issuing genset start signal after abnormal delay of one way. By LINK communication port, "three remotes" (remote measurement, remote communication and remote control) function can be realized. 


  1. Measure and display 2-way 3-phase Voltage and Frequency:

    1#                                 2#

    Line voltage   (Uab, Ubc, Uca)    Line voltage   (Uab, Ubc, Uca)

    Phase voltage (Ua, Ub, Uc)        Phase voltage (Ua, Ub, Uc)

    Frequency    Hz                 Frequency    Hz

  2. Over/under voltage, loss of phase, phase sequence wrong, over/under frequency protection function. As default, phase sequence wrong protection and over/under frequency protection are disabled; however, users can set the protection function as you need.

  3. LINK communication port (SmartGen SG72 adapter is needed), with which controller parameters can be set and firmware update also can be realized. 

  4. The voltage normal delay of 1# or 2# can be set (Range: 0s~60s) and Genset start delay can be set (Range: 0s~3600s). 

  5. The voltage abnormal delay of 1# or 2# can be set (Range: 0s~60s) and Genset stop delay can be set (Range: 0s~3600s). 

  6. “1# Master”, “Each Backup” and “2# Master” can be set via controller front panel, so that 1# power master supply, or 2# power master supply, or mutual backup power supply for each other can be realized. 

  7. Close output signal can be set as pulse or continuous output.

  8. 2-way N-wire isolated design.

  9. Auto/Manual mode transfer. In manual mode, ATS transfer 1# switch or 2# switch can be implemented via panel pushbutton.

  10. LEDs mounted on front panel can clearly show ATS running status.

  11. The output contactor capacity of 1# and 2# power transfer relay (1# CLOSE, 2# CLOSE) is 16A AC250V, volts-free contact, which can be directly used in driving switch to transfer. 

  12. The output contactor capacity of Genset start relay (GENS START) is 7A AC250V/7A DC28V, volts-free N/C contact.

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

  14. Modular design, flame retardant ABS plastic shell, pluggable terminal, built-in mounting, compact structure with easy installation.
