Abstract

The utility model relates to an energy saver for the client module of a program controlling exchange device, comprising a connecting state control unit having the structure that pins form two state structures of normal and stand-by corresponding to the client module. A stand-by power management unit and a stand-by client line power feeding control unit are respectively controlled by the stand by state of the connecting state control unit. Because when the utility model is in the stand-by state, the client module works under low voltage power supply, and high power consumption for high voltage power supply operation in the normal state is changed. 10% of client line occupation is used for calculation. The energy saving effect is obvious. In addition, the standards of post and telecommunication can be ensured.
