SU2C12AC is an integrated distributed power system specifically designed for elevator rescue power supply. It is based on SU2C series, designed on the basis of European elevator power supply system and integrated with off-line AC UPS elevator drive system, which has the characteristics of fast response and strong anti-interference.

In the application of SU2C12AC system, the integrated distributed power system combines the functions of light load environment power supply and the requirements of large power power supply in the rescue area, such as air conditioners, elevators, lighting and public address systems. The main power supply adopts offline AC UPS device, which can independently or cooperate with the power supply system to supply power to the elevator in real time. When the mains power fails, it can quickly cut off the power output of AC UPS. It changes with the change of external power supply, confirms whether there is power supply or not in a few milliseconds, and quickly starts to switch, which is suitable for use in elevator application system.

The working principle of SU2C12AC system, when the external power supply is normal, the system is powered through the AC power grid, and the required power current is provided by the corresponding AC power supply module, which is converted by its own AC UPS into DC power supply to the inverter input through DC power supply module. When the external power supply is subjected to a power failure, the DC power supply module will send a signal to the control logic of the UPS, and the AC power supply module will be cut off to activate the emergency power supply system, which is powered by the auxiliary power supply.

The working principle of SU2C12AC integrated distributed power system is simple and stable, and has greatly improved the level of energy saving of the traditional rescue power supply without the need for a large number of lines and large DC batteries. Therefore, it is more suitable for the application of elevator rescue power supply.
