Dc adapter 12v 3a, giving stable and reliable power, adopting this type can provide a 12v steady current at 3 amperes. She is designed with precision voltage regulation to that your machine receives the correct amount of power when at work. In this way you can get away from common PC problems like sudden shutdown, slow boot times, or Internet connection issues caused by insufficient voltage from an unstable AC adapter. It has a wide variety of protective measures in place, including overvoltage protection, over current protection as well as short circuit and reverse polarity protection; this guarantees that your devices are always safe. It has highly integrated functions, powering various electronic products (for example routers, modems or security systems.). Technological features: a wide input voltage range, low ripple and noise, high efficiency; it is therefore suited particularly for use with sensitive electronic equipment. In terms of applications, it has enough flexibility to be used in various areas such as home, office, industrial situations, where reliable and stable power is demanded.
