he power module and the protection plate according to different circuit parameters for different, select the power module has its own unique effect. Nanjing pengtu Power Co. Ltd to introduce you to the power module choice points.

The principle of discharge protection when load discharge connection module power supply of the electric core, also with the discharge voltage and slowly decrease. When the voltage drops to a certain value, the electrical core telephone will be in a discharge state. When the solenoid is through the charger, charging time increases with the voltage of electric core will also increase. When the charge reaches a certain degree, the voltage reaches a certain value, the electrical core will be in a state of over charging voltage, charging electric core will be disconnected.

A form of module power supply short circuit protection is also the current protection, the principle of his principle with current protection, load current exceeds a certain protective effect of current numerical will.
