  Power adapters have been widely used in people’s lives, but a large number of power adapters of different quality are also flowing to the market, but I don’t know how much do you know about the material of the power adapter shell? Next, I will introduce you to the power adapter shell. Material differences, everyone knows more about this kind of related information, and can also avoid some safety hazards to a large extent!

  The power adapter shell is generally made of plastic materials, of course, some industrial power supplies use metal shells. The materials of our common power adapter shell mainly include ABS material, ABS+PC material, and pure PC material. In general, we only use these three materials. Let's introduce the differences between these materials one by one.

What material is the power adapter? What are the characteristics of the power adapter?(图1)

  PC material

  Pure PC material has ultra-high strength and elastic coefficient, and it can be used in a wide temperature range. (The general material of ABS can only be used at -25 degrees to 60 degrees). In addition, PC material has high transparency and free dyeing properties, so that The power adapter is very good in various colors. In addition, this material also has fatigue resistance, weather resistance, odorless, odorless, and harmless to the human body, which is in line with hygiene and safety.

  ABS material

  ABS material characteristics, first of all, low strength, not temperature resistant, under normal circumstances, the maximum use temperature can not exceed 60 degrees Celsius, this is a lot worse than PC materials, ABS is generally used in household appliances.

  Synthetic material of ABS and PC

  Taking the characteristics of the first two, it has excellent molding processing performance, good fluidity and high strength. ABS+PC material is easy to process, has good processing dimensional stability and surface gloss, easy to paint and color, and can also be used for secondary processing properties such as spraying metal, electroplating, welding and bonding. Due to the combination of the characteristics of ABS with the characteristics of its three components, it has excellent comprehensive performance and becomes one of the preferred plastics for electrical components, home appliances, computers and instruments.

  In the choice of power adapter shell materials, pure PC materials and PC+ABS are basically the main ones. Although the cost will increase compared with the past, the price of power adapter will also be different, but from environmental protection and safety. Said that ABS is less and less suitable for the current market demand! So the power adapter manufacturer Shenzhen Xinjukang Technology Co., Ltd. reminds you, when choosing a power adapter, try to choose a regular manufacturer to buy!

  Power adapter features

  1. Small size and light weight. Switching power adapters do not use bulky power frequency transformers. After the power dissipation on the switch MOS tube is greatly reduced, a larger heat sink is omitted. Due to these two reasons, the switching power adapter is small in size and light in weight.

  2. Low power consumption and high efficiency. In the switching power supply adapter circuit, the switch MOS tube is activated by the excitation signal, it alternately works in the on-off and off-on switching state, the conversion speed is very fast, the frequency is generally above 50kHz, in some advanced switches In the power line, it can be hundreds or nearly mega Hz. This makes the power consumption of the switching MOS tube very small, and the efficiency of the power supply can be greatly improved, and its efficiency can reach 90%.

  3. The efficiency of filtering is greatly improved, and the capacity and volume of the filtering capacitor are greatly reduced. The operating frequency of the switching power supply adapter is basically above 50kHz at present, which is more than 1000 times that of the linear stabilized power adapter, which makes the filtering efficiency after rectification almost 1000 times higher; even if half-wave rectification is used and capacitor filtering is added, The efficiency has also been increased by 500 times. Under the same ripple output voltage, when the switching power supply is used, the capacity of the filter capacitor is only 1/500~1/1000 of the filter capacitor in the linear stabilized power supply.

  4. Wide voltage regulation range. The output voltage of the switching power supply adapter is adjusted by the duty cycle of the excitation signal, and the change of the input signal voltage can be compensated by frequency modulation or width modulation. In this way, when the power frequency grid voltage changes greatly, it can still ensure a relatively stable output voltage. Therefore, the voltage regulation range of the switching power supply adapter is very wide and the voltage regulation effect is very good. In addition, there are two methods for changing the duty cycle: pulse width modulation and frequency modulation. Switching regulated power supply not only has the advantages of wide voltage regulation range, but also has many ways to realize voltage regulation. Designers can flexibly choose various types of switching power supply integrated circuit chip schemes according to actual application requirements.
