Dual power automatic transfer switches, ATSE for short, are also known as automatic transfer switching equipment, commonly known as dual power switching. In the case of a sudden power failure, the switch can be automatically connected to the backup power supply, to ensure that the equipment operation does not stop, can still continue to run.
The use of dual power automatic transfer switch is relatively simple, that is, all the way to the main, all the way to standby. When the commonly used power supply suddenly cuts off or fails, the dual power automatic transfer switch will automatically put into the backup power (the backup power can be supplied by the generator in the case of small load), so that the equipment can run normally. The most common application scenarios include lifts, fire protection, monitoring and bank UPS, etc. However, the backup power of bank UPS is battery pack.
