Wall Outlet And Adapter

With all the certifications UL, ETL, FCC, CE, CB, GS, CCC, CQC, PSE, KC, KCC, SAA, RCM, etc.

PD power adapter converts 220V AC power to DC power suitable for power equipment, consisting of components such as shell, transformer, inductor, capacitor, control IC, PCB board, etc. It is widely used in cell phones, laptops, cameras, set-top boxes, routers and other electronic devices. Because the connection is 110-220V household electricity, so manufacturers for the use of safety and stability will generally set up the most basic four protection circuits within its circuit.

1 Short-circuit protection: With short-circuit protection, the power adapter can withstand the impact of high current brought about by a short circuit. When the fault disappears, the adapter can recover from the protection mode and provide the rated power again.

2 Over-voltage protection: In the case of a broken loop, such as a damaged optocoupler or a compromised TL431 voltage divider network, the adapter must stop working immediately and remain in this state until the user restarts the adapter.

3 over-temperature protection: power adapter in the 220V AC power into DC power, part of the electrical energy will be consumed, through the way of heat through the air to emit, where if the heat is too late to emit, and accumulated to a certain amount of temperature over a certain temperature value, the adapter will be destroyed. Therefore, the general power adapter will be equipped with a thermal sensor to monitor the temperature, and in the case of temperature exceeding the limit value set by the designers, the adapter will automatically power off. When the user restarts the power supply and the temperature drops, the adapter resets.

4 Over Power Protection: For some power supplies, it is important that the maximum output current remains in a controlled state under the worst conditions - such as when the load draws too much current - without actually short-circuiting, which UE power supplies do.

Eahunt power supply manufacturers specialize in the research and manufacture of adapters, all of which are protected by 8 circuits such as overcurrent, overvoltage, and anti-reverse current, making them safe and trustworthy.

Eahunt is a source manufacturer and all products are factory direct, so the price is very affordable.
