Dual power automatic transfer switch (ATSE) as an important power supply even essential components in the development and application of the developed countries in Europe and America has more than 100 years, dual power supplies introduced into China in the 1990s, has been more widely applications and technologies for the future development of dual power, what should we do what prospects it?

Future dual power will be in the high reliability, high performance, small size and other aspects of the development of multi-functional intelligent:
1、High reliability
The operating mechanism is more simple, stable, EMC performance dual power controller has been further improved
2、High performance
The ability to withstand short-term than the short-circuit current level ACB or MCCB; making and breaking capacity (overload characteristics) reached 10Ie; Iq reach 100 ~ 200kA; electrically operated capacity to meet the standards specified in Class A requirements; having relatively under 690V high-tech index (using the categories of not less than AC-33iA); controller has a power failure diagnosis, phase angle detection and other functions, synchronization of the conversion of not more than 7 degrees.
3、Small multi-purpose intelligent
Future dual power will use green, recyclable materials, and the products will be more compact and versatile intelligent
1）Bypass dual power: do not power off-line repair and maintenance
2）Drawer-type dual power
3）Instant parallel dual power
4）Electronic Dual Power ATSE products - Static Transfer Switch (Static Transfer Switch referred STS), to meet the rapid conversion (5 ~ 10sm) requirements.
5）Can communicate features: LAN (RS232 / RS485, CAN, etc.); wired communication (ModBus, Profibus, DeviceNet, Industrial Ethernet, etc.); wireless communications: (ZigBee, WinFi etc.); all attachments with a communication interface, and can with a variety of open fieldbus compatible; with the overall plan to resolve the emergency power supply system.
