introduction：People in the field of switching power supply technology are developing related power electronic devices，Development of switching frequency conversion technology，The two promote each other to promote the switching power supply with more than double digit growth rate towards light every year、small、thin、Low noise、High reliability、The direction of anti-interference development。Switching power supply can be divided intoAC/DCandDC/DCTwo broad categories，DC/DCThe converter is now modular，And the design technology and production process at home and abroad have been mature and standardized，And has been recognized by users，butAC/DCModularity of，Because of its own characteristics make in the modular process，Encountered more complex technical and process manufacturing problems。The structure and characteristics of the two types of switching power supplies are described below。

introduction：Power-off time delay relay，Is when the time relay coil is energized，Instantaneous action of each delay contact，After the coil is powered off, the contact is in a delay setting working state，When the set delay arrives，The delay contact is restored to the initial state。Blackout delay type due to its working state（No external power supply is required during the delay process）And the control contact in the power delay process suction contact（If the normally open contact becomes connected, keep it connected;The normally closed contact becomes open，It should be in the hold disconnected state）Transformation particularity（The working state of the contact of the conventional electric delay time relay is exactly the opposite）To meet its control requirements。The power off delay type time relay is composed of an early separation device（Low delay accuracy、Short delay time）;The corresponding programmable timing integrated circuit orCMOSCounting and frequency division integration to complete the delay，Compare with，With hig
