Q: Please elaborate on the specific differences, available examples can be explained, thank you: Charger, switching power supply, power adapter can (but not necessarily) is a thing, Switching power supply is to pay attention to the internal characteristics of the items, the charger is to pay attention to his use, power adapter is highlighted as the main equipment of the auxiliary. Such as ---- porcelain bowl --- switching power supply ------ refers to the bowl is made of porcelain ????? Rice bowl --- charger ------- refers to the use of the bowl (Note that the charger is not a switching power supply to do, rice bowl also has a glass bowl) ????? Tableware --- power adapter -------- refers to the service for the meal (power adapter also has a transformer AC output, the ordinary linear rectifier regulator output, as well as battery box. Tableware also has dish, spoon, etc. )

Q: Note the operating conditions of 220V voltage and the order of switching power supply: 220v are low-voltage circuit, there is no provision, as long as the attention of several points: 1, do not touch the live part directly. 2, if you want to live work, you must ensure that the human body and the earth insulation (standing on the bench or insulation pad). Can not touch FireWire and Neutral Line at the same time. 3, the normal operation of the order: to use the switch off the circuit, first pull the sub-gate and then pull the total gate, the first joint gate and then sub-gate. Line maintenance sequence: Power off - pull the security ground - proof signs pull off the line - operation - review the operation is correct to complete the task - remove the insurance ground - remove the warning card pull off the line - power

Q: 12V switching power supply, which brands through 3C certification?: Big brands have, sailing, the Great Wall, technical exhibition ..... N more ...

Q: What brand of switching power supply cost-effective?: To plc power supply The power requirements are still relatively high, EMC to pass, you see a lot of small, and how much output power you use. Structure size, if there is a suitable with the best, not to be customized. Can be added QQ detailed chat ah.

Q: Hello everyone, I have a switching power supply chip with UC3845, fault: turn on the power instantaneous power indicator light and then off. After the investigation did not find a short circuit phenomenon. When the shortcomings of several consecutive shortcuts on the receiving side of the two pins, the power can be activated. What is the reason for this? thank you all!: In addition, increase the output capacitor, will only increase the impact of the starting current, no way to start. Reduce the voltage is not feasible, because it would lose their own meaning, and for a large switching power supply that can be considered a problem, wasted. Analysis of the actual current detection link and peak and power limit links, because they do not know what specific program, so do not know, the appropriate tune can be a little bit.

Q: How to choose the switching power supply frequency?: such as 300KHZ better magnetic material can do 500KHZ or more high. Input voltage and then higher, we need to pay attention to the switch tube switching loss problems, and generally only to do dozens to hundreds of hundreds of KHZ or so. The specific circumstances of the specific analysis, and some soft-switching, resonant what the high-power high-efficiency topology!

Q: Switching power supply, starting resistor is very hot, no output. What is the reason.: You ask the question is the common problem of switching power supply, you have to study the power schematic diagram! Practice basic skills.

Q: Is switching power and transformer the same thing?: This is not a matter of time, the switching power supply is to control the power supply, the transformer is to change the size of the voltage, the transformer in the case of power to control the voltage.

Q: 12V10A switching power supply in the layout of the line when the longest cloth?: Most of the time with seven infrared one machine, the nearest infrared machine 15 meters, farthest infrared one machine 110 meters. Cloth RVV2 * 1.5 power cord

Q: Why switching power supply with two series capacitor filter, with a can you: Two series to increase the pressure, improve the reliability of the power supply.
