AC DC Switching Power SupplyEvery day, we need electricity to power on the daily devices. Let’s see how it work. After the power plant sends thousands of AC high voltages of 20,000 volts, it is stepped down to 100V and 200V through the transformer in the pole before being sent to the general household. The outlet in the house supplies AC power, so after the AC/DC power supply conversion circuit, the DC power is supplied to the household appliance.The type we insert into the appliance is open frame power supply. Another with a plastic case, AC plug/AC inlet and DC connector is power adaptor. As to the usages, there are IT switching power supplies, medical power supply units, battery chargers, USB chargers and DC DC car adaptors. These are on Astek’s power supplies product lists.About the switching power supplies design, at the initial stage, the required specifications must be confirmed.1. Input voltage range, output voltages/currents2. Standby power3. Max./min./cooling temperature4. The allowable area/heights in size5. Necessary protection: such as overcurrent, overvoltage, and over temperature6. Special environments/application: like used in tropic zone or with aerospace…7. CostsEvaluation and trial1. Use evaluation board / work2. Make a test board, run under preset conditions and evaluate performance3. Debugging, optimization4. Distinguish Compliance / non-compliance with specifications and safety standards.5. Reserved space for modification and upgrade by customers’ demand or when new safety standards enforced.When evaluating, carefully check the output voltage, load current, temperature upper limit, etc. If the design is not able to withstand the temperature, it is easy to deviate from the required specifications during mass production, or because the batch affects the yield. The characteristics of the components that make up the circuit are different, so it is important to understand the characteristics of the part and design an article that meets the specifications. During this period, it’s critical to choose the right components, power supply layout and circuits.After then, the design of power supplies is closed to complete and initiate the mass production. Before the shipments, our factory will inspect with Chroma and 100% burn-in tests.Any inquiries, please feel free to touch us. https://www.astekglobe.com/hot_317390.html AC DC Switching power supplies 2020-11-26 2021-11-26

Story about USB charger adapter

In this world, devices are smaller, more multiple functions and convenient with time. So do charger design, especially USB charger multiple ports. There are USB 1.0/2.0 with 5V/500mA and battery charger 5V/1.5A; USB 3.0 5V/900mA; USB 4.0 3A max @3V/5V/15V/20V, USB power delivery 5V~20V @5A max, USB power delivery with programmable power supply 3V~20V, 5A max.

USB chargers are really miracle like mobile. A mobile is a phone, notebook, camera, TV, MP3secretary, messenger, and exercise trainer and so on. USB chargers catch these demand with dramatic changes.

USB chargers not only transmit power source and absorb surplus power but also data and signal at the same time; dual roles of power and dual roles of data. That's why USB type C can reach 3V and 20V with programmable power supply by USB power delivery. Thus, its applications get wider and wider, which are from mobile devices to vehicle equipment. Some experts predicted vehicles equipment will be the next trends.

Astek USB charger best buy includes the uses of USB 1.0/2.0, USB 3.0, USB 4.0; from type A to C; from AC DC usb charger battery to DC-DC usb charger for car; between wall mount and desktop. Accept customized design too. If more inquiries, please feel free to touch us info@astekglobe.com asap. Thank you.
