The protective function of power source basically is to be pressed too, shed protection too two kinds of functions.

Both the relation between is:

A kind of any power source are in when malfunctioning, make likely output voltage or output electric current to lose control, to make the load of the user does not cause because of this damage, the power source of my company has been set commonly press and shed protection too. Some load are like block sex load, have trouble when power source, the voltage on load rises considerably likely, and ascendant value of electric current can have not exceeded certainly shed protection to be worth. Appropriate of this kind of circumstance has been used press protection, work for example in 50V, can protect voltage the value to be moved to 55V, if power source breakdown wants voltage to rise only,come when 55V, power source can cut off voltage automatically to output. Should having some of load is the load that allow a gender when, as a result of high capacity electroanalysis capacitor paralell connection is together, when power source malfunctions, electric current rises possibly substantially, and of voltage appreciate very not apparent however, at this moment of power source interior shed protective component to be able to be started above all too, power source can cut off output automatically.

Press protective value to there is a potentiometer on face plate too, OK and artificial set. And shedding protection to be worth too is cannot of artificial set, classics of the Si inside machine dies surely, the 1.2 ～ that are rated electric current commonly 1.5 times. Those who need a specification is, press protection to be able to be started quickly instantly too, shed protection to have the delay time that one second influences too. Because work normally like power source,this is when, if the load of power source produces abrupt short circuit, the instantaneous electricity that right now power source exports is multiple or values of tens of rated electric current of times, can consider as an electric current concussion, had exceeded the numerical value that sheds protection far, but had not hoped to shed protection to act well at this moment. And after hope short circuit removes, voltage returns to normal automatically. When because this has been being designed,shedding protection, want the voltaic concussion when escape breaks out short circuit, and the value with when considering those who had exported electricity to make only, be as long as fair just has been started shed protection.

Press too, shedding protection too is to be aimed at the breakdown inside machine, accordingly since happen, power source should not restore automatically. If must emersion, must close machine hind to switch on the mobile phone afresh. And short circuit protection, electric current calls the police, short circuit warning function faces an user, if voltaic Si classics drops, classics of short circuit Si eliminates, call the police relatively sound can remove automatically, voltage can return to normal automatically.
