What's the difference between AC socket and DC socket? What should we pay attention to when choosing and using AC socket?
AC socket and DC socket are devices that convert one AC voltage into another (or several) DC voltage by AC input circuit, rectifier circuit and switching device.
And socket, power supply is divided into two types of isolation, non-isolation, here the "isolation" and "non-isolation" are for the grid. Isolated socket power supply is also called off-line socket power supply. It belongs to AC socket and DC socket. Its characteristic is to isolate the output voltage from the power grid through high-frequency transformer and optocoupler feedback circuit, so that the switching power supply meets the required safety standards. Isolated socket power supply has good security, but the circuit is more complex, the cost is higher; non-isolated socket, the power supply circuit is simple, but the security is poor. It should be selected according to the design socket, power supply's usage and safety specification. For example, according to the relevant standards, some white household appliances (such as household air conditioners, dishwashers, rice scalding, refrigerators, household appliances heaters, etc.) internal control power, allowing the use of non-isolated switching power supply to reduce costs, because manufacturers prohibit users from self-repair, so can avoid the occurrence of safety accidents.
