XI. Double Power Automatic Transfer Controller
The NQ6W Double Power Automatic Transfer Controller
(hereinafter referred to as “the controller”) controls the frame circuit breaker. It is
suitable for important power supply places where power supply failure is not allowed, and can complete the automatic transfer of power supply
system, thus ensuring the continuity of power supply. The product has the following features:
● The silicon controlled rectifier (SCR) is adopted to enhance the earthquake resistance and reliability.
● The measurement and control system is built with 32bits-MCU as the core, embedded with 12bits high-speed and high-precision analog-to-
digital converter (ADC).
● The three-phase voltage of each power supply can be completely measured. The voltages of each phase of the power supply are calculated
by the True-RMS method.
● The secondary connection between the controller and the circuit breaker has good operability and maintainability.
● The electromagnetic compatibility capability beyond the requirements of GB14048.11-2008 is available.
● It has the function of system fault self-diagnosis to improve the reliability and safety of the device.
