12v 5a ac dc adapter
As the current produced by a wall socket is not in that form our various electrical devices require, 12v 5a ac dc adapter and others like it were developed for converting this alternating current to direct. The stable output of 12 volts and 5 amperes is essential for devices needing a specific voltage level. With advanced circuitry and features for safety, it protects both the adapter itself as well as whatever device you have plugged into it: between loads which may lead oncoming surges shortening lifetime over-voltage can cause problems or at worst accidents--with lightning. For people working on projects, such as small security systems powered off-grid and occasional classes of battery-powered devices that all require precisely 15 volts or 11 Hz frequencies to operate properly,it is the 12v 5a ac dc adapter of choice.
