Elbow 5.5mm 2.5mm Connection Laptop Charger For Lenovo

• General adapters are divided into general adapters and switching power adapters. Common adapters are large in size, low in cost, simple in principle and easy to maintain. The switching power adapter is small in size and complex in circuit. The function of the power adapter is to change the voltage. In the process of voltage conversion, a part of the power needs to be consumed due to loss. After the electrical energy is converted into heat energy, part of the heat energy is transferred to the surrounding environment by radiation, convection and conduction. The other part of the thermal energy itself is absorbed, warming the adapter. So when the ambient temperature is too high, we should stop using the power adapter.

• Short circuit and overload, there are hidden dangers. Or in the output short circuit, capacitor diode under the condition of short circuit, the internal loss of the power adapter has increased dramatically, leading to the rise of temperature of the each part, the design and application of electronic circuits shall ensure that work in the abnormal and fault conditions, product temperature rise of each part can not exceed the prescribed requirements, otherwise the consequences of a short circuit, even can cause fires.
