WPQ2 series automatic transfer switch is the best development of the company generation products. Mostly used to monitor the power supply circuits. When main power failured, it will change over to backup power by automatically, thus completing the transformation of power system . At present, in particular suited for the important electricity power places where disallow to failure, in order to meet the needs of the scene. Automatic switch has self-input and self-recover,self-input without self-recover, utility to utility, utility-generators work with variety functions, the product applied in 220V,AC 50Hz,rated current from 10A to 1250A (CB class) automatically switch products.

1. Adopt the double row type composite contact,side pull institutions, micro motor prestore and microelectronics control technology, come true zero flashover (no arcing chamber).
2. Reliable electrical and mechanical interlocking chain, the implement of the components indepen dently with islation switch, the use of safe and reliable.
3. Using over zero technology, the state of emergency can be enforced under the zero(cut down the 2 ways in the meanwhile) to meet the needs of fire fighting.
4. Executive load isolation switch using a single motor-driven, transfer reliable smooth, no noise, little impact.
5. Operators drive only in the implementation of the electrical load isolation by switching transient current, steady work without providing current, energy-saving significantly.
6. Executive load disconnector chain with a mechanical device used to ensure that reliable standby power of non-interference in each other.
7. Obvious off position indicator, padlocks and other functions, high reliability and service life of more than 8000 times.
8. Mechatronics design, switching conversion accurate, flexible, smooth and adopt international advanced logic control technology, anti-interferencecapability, without external interference.
9. Cooperation with the main power on and standby power off, or the main power off and standby on, the main power and standby power are both off, three kinds stability working. (I-O-II)
10.Easy installation, the control circuit return way adopt the connect and insert terminal connector.
11.Four operator models: emergency manual operation, electric remote control operation, emergency disconnected operation under the automatic stating, automatic control operations.
