1300940311

1300940311 is a programmable frequency law time switch, which is mainly used in the control of load start/stop and other timing as well as time limit control in power distribution system. The application field of 1300940311 includes automatic control, street lamp control and power monitoring in urban and rural power networks.

1300940311 provides two kinds of control modes: one is duty cycle control, the other is sine wave smoothing control. The duty cycle control can adjust the output of the device at any time. The duty cycle is determined by the set parameters. The sine wave smoothing control can output a smooth sine wave with the specified frequency. After the start or transfer of load, it can carry on the corresponding current limiting. In this way, the start or transfer of load will be processed in an orderly manner, and the harm to the power grid can be avoided.

The working principle of 1300940311 is relatively simple. There is a low speed counter inside the device that is used to store timing information. After power-on, the device will start counting the time set by the parameter according to the pre-set timing information. When the device reaches a certain time interval, then the corresponding output is started, and the parameters of timing signal will be reset until the specified timing is reached again.

In conclusion, 1300940311 is a programmable frequency law time switch, which has wide application fields. Its duty cycle control and sine wave smoothing control are the main working principles.
