What are AC outlets and DC outlets, blocking outlets?

What is the difference between AC socket, DC socket and blocking socket, Dongguan Huangjiang Haochen Mould Factory explains:

　　AC sockets and DC sockets are devices that convert one communication voltage into another (or several) DC voltages through communication input circuits, rectifier circuits and switching devices.

　　 And the socket power is divided into two types: barrier type and non-blocking type. The "blocking" and "non-isolating" mentioned here are all for the power grid. Blocked socket power supply is also called off-line socket power supply. It belongs to AC socket and DC socket. It is characterized by high-frequency transformer and optocoupler reaction circuit to end the blocking of output voltage and power grid, so that the switching power supply conforms to the rules. Safety regulations.

The safety of the barrier-type socket power supply is good, but the circuit is messy and the cost is high; the circuit of the non-blocking socket is simple, but the security is poor.

　　 should be selected according to the planned socket, the use of the power supply and the safety regulations. For example, according to relevant specifications, the control power supply inside certain white goods (such as household air conditioners, dishwashers, rice cookers, refrigerators, household electric heaters, etc.) promises to use non-blocking switching power supplies to reduce costs. Because the manufacturer's rules prevent users from repairing themselves, they can prevent the occurrence of security incidents.
