What is Power Supply Adapter
  • AC / DC adapter AC adapter (AC adapter) (Japanese AC アダプター) (AC / DC converter), AC means alternating current, and AC adapter is AC power supply. Many electrical appliances use AC adapters. The name of AC Adaper is only used in commercial products. In fact, it is an AC power supply. In the industrial field, we call it switching power supply , but there is a little difference in appearance.

  • China Best power adapter Manufacturer & Supplier

  • Power adapter, trustworthy, USB charger, DC power controller, 25 year brand, product line includes high-frequency transformer, product line includes LED TV power supply, exclusive patent, strict implementation of ISO9001, production and sales.

  • What is the power AC & DC Adapter?

    Power adapter is a power supply conversion equipment for small portable electronic equipment and electronic appliances. It is generally composed of shell, transformer, inductance, capacitor, control IC, PCB board and other components. Its working principle is to convert AC input into DC output. According to the connection mode, it can be divided into wall type and desktop type. It is widely used in security camera, set-top box, router, light bar, massage instrument and other equipment.

  • Instructions for power adapter, AC to DC Adapters

    There are several items that need attention on the label of the power adapter (hereinafter referred to as adapter). First, the model of the adapter. For example, the model of the adapter is xve-120100, which tells us several information, such as its manufacturer and main parameters. The beginning of xve is generally the company code, 120100 means that the adapter is 12V1A, and 050200 means 5v2a. The second is the input of the adapter, which is generally AC100-240V ~ 50-60Hz in China, which shows that the adapter can work normally under the AC voltage of 100v-240v. The third is the output of the adapter. DC 12V = 1a, which represents DC with rated voltage of 12V and maximum current of 1a. Two numbers can quickly calculate the wattage of the adapter. For example, the voltage of the adapter is 12V * the current 1A = 12W (power), indicating that the power supply is a 12W adapter.

    The power adapter of most notebook computers can be suitable for 100 ~ 240V AC (50 / 60Hz). Basically, most laptops have an external power supply and are connected to the host with a power cord, which can reduce the volume and weight of the host. Only a few models have a built-in power supply in the host.

    There is a nameplate on the power adapter, which indicates the indicators such as power, input and output voltage and current. Pay special attention to the range of input voltage. This is the so-called "travel power adapter". This feature is very useful if you go to a country where the mains voltage is only 110V. Some parallel laptops are sold only in the country of origin, Without this compatible voltage design, even a single input voltage of 110V will burn out if it is inserted under the 220V mains voltage in China.

    Purpose of power adapter

    Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting , industrial control equipment, communication equipment, power equipment, instruments and meters, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, liquid crystal display, LED lamps, audio-visual products, security, computer chassis, digital products and instruments, AC linear power supply.

  • What is an AC Adapter - and Why Would I Need One?

    An AC adapter, also known as a power adapter, charger, wall charger, power brick, or wall wart, is an external power supply that converts alternating current (AC) from a wall outlet into direct current (DC) for electronic devices. The DC power then flows through the cable to the device, where it's used to charge the battery or power the device directly.

    FBelec as AC adapter supplies power to a battery-powered device, it is also accurate to describe it as a charger.An AC adapter can be used to provide sufficient power to operate a laptop for extended periods and to recharge the laptop battery.

    Each AC adapter has a specific power rating, measured in volts or wattages that it can handle and output to an electronic device. Because the power rating and type of plug is not universal the AC adapter can only be used with devices with the same requirements and connector.

    If necessary, a universal AC adapter can be used, which is designed to work with many devices, having multiple types and sizes of plugs for connectivity to those devices. A universal AC adapter may also have a voltage or wattage range, like 100 volts to 240 volts or 70 watts to 125 watts, allowing for a greater range of compatible devices.

    Why do you need an AC/DC adapter, though? Maybe the power coming from the mains is not the type that your device needs to work. The mains produces a general-purpose alternating current (AC) electricity power supply while your device needs direct current (DC).

    Luckily, it is possible to convert from one type of power to another with the help of AC adapters. Sometimes, AC adapters also double as a charger for devices that run on batteries, such as laptops and phones.

    External power adapters are popular because they make devices more portable, are easy to troubleshoot and replace if necessary, dissipate low heat, emit low noise, and are generally safe to use.

    The Different AC-DC Adapter Types

    There are numerous AC-DC adapter types, depending on the classification.

    One classification is based on the plug type. Different countries in the world use different wall socket designs. For example, British plugs feature three conducting pins while Australian plugs have a three-blade design. In America, we use the two-blade arrangement, and this is what you should get when replacing your AC adapter. If you are a regular international traveler, it is advisable to get a plug adapter that suits the wall socket design of your destination country.
