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 2021-07-27 2022-07-27

Requirements about White medical adapters from Japan customer

Some time, one Japan customer inquired the adapter in white with PSE medical grade. Though it’s all right for us to provide medical white adapter, there were two points we had to highlight:

1) Concerning PSE, there are no medical grade for adapters, but with IEC60950-1 normally.

Let’s brief talk about PSE of Adapters. About adapters, it’s mandatory level, Specified Products: Category A by Japan Denan Law. Certification accreditation Body(CAB), recognized by METI, responsible for product certification and factory inspection. PSE validity is 5years. After approval and before import to Japan, the local representative register with duplicate to METI.

2) Due to color difference on adapters and AC cords, we would check what the customer Pentone color code is or if standard white acceptable. After that, when samples of plug pack made, there are color difference between adapters and AC cords. So, it’s critical at samples stage for sample tests and checking colors.

We explained them Japan PSE certification and registration from local representative. Also, we suggest them choose Astek medical adapter with IEC60601-1 and IEC60950-1 because of global markets and more suitable in use with medical devices.

At the same time, before samples made, we checked the details of specifications and white color carefully. The project went through samples, try run and mass production stages till now. It took several months to run those procedures, however, it saves more time and costs in use in now and future.

It’s the regular procedures to cooperate with Japan customers. Prevention is better than treatment. It’s not easy to work with them but you will learn more from them.
