Q: I encountered a similar problem with you, I use the 12V switching power supply with dimming decoder, into the dimming console DMX512 control, in the dimming when the switching power supply is creak sound, ask you there A better solution? thank: , I personally think that electromagnetic excitation of this, in addition to resonance, the other amplitude is very small

Q: How to identify the computer motherboard and switching power supply, restart, hard disk plug: 2, HDD LED is the hard disk indicator, the general is the vertical look, + there is a positive side, - or not sign there is a negative side, the chassis is also reserved for such a plug, corresponding to insert the corresponding board can be set The HDD LED lights feet can not be inserted, plug the indicator light is not bright.

Q: How to make the switching power supply does not delay power: Use a relay to control the output of the switching power supply.

Q: Is switching power not power? Why should the word "switch" be added?: Switching power supply its working principle is not the same, first of all it will be the main power through the rectifier into a DC with a fluctuation, coupled with the capacitor and other energy-saving front-end components, and then through the transistor (MOS tube) and other devices will be a DC Intermittent form added to the high-frequency transformer, the use of inductive induced current in the secondary level to produce the required current or power. ???????This is the power of a lot of advantages, one is the small size of light weight. Second, the same power cheap, the third is high efficiency, four is the output voltage stability, can allow the input voltage has a large fluctuations without affecting the output voltage. ??????Disadvantages are: manufacturing more complex, covered with more knowledge, electromagnetic interference is relatively large, high power on the power grid is relatively large.

Q: "First AC into DC, and then into a higher frequency of alternating current through the high-frequency transformer voltage conversion" Why? "LED display as a high-precision instrument to select the switching power supply instead of the transformer" Why?: Switching power supply and the difference between the transformer is a very stable switching power to a certain range of voltage into a very low voltage or high voltage (such as 110V-250 input, the output voltage can be stable control in the required voltage plus or minus 0.5 V)! Transformer output voltage is changing with the input voltage, that is, the input voltage increases the output voltage is also increased, the input voltage to reduce the output voltage is also reduced. Because the switching power supply is the first AC into DC, DC power through the power switch and then become a higher frequency of alternating current through the high-frequency transformer voltage conversion is not only efficient and high frequency after the greatly reduced the volume, but also save the copper and iron loss. Because the switch is controlled by the power switch, the switch is turned on for a short time and the output voltage can be maintained. When the load is large, the switch keeps working to keep the output voltage. So the switching power supply output voltage is stable, can be used as LED display and other high-precision instrument selection.

Q: Switching power supply start-up time, hold time, long time, fall time, which standard: Rise time: the output voltage from 10% to 90% of the time, the rise time is generally less than 50ms, too long may cause the machine malfunction. Hold time: After the input power is turned off, the output voltage is maintained with 90% of the specification time.

Q: I bought a 3C certification 12V 500mA power adapter, I use 15 ohm 5W resistance to measure the voltage (12V, current 800mA) supposedly the specification is 500mA, more than 600mA should be protected, but why will show 800mA The The In addition, I use 10 ohm resistance to measure it to protect, is not the way I measured is not so measured? Or is this power adapter not 12V 500mA specification but 12V 1A? The The Solve? The Seek test method The: The rated value is connected to the 500mA pure resistance load current measurement.

Q: Switching power supply efficiency: The lower the output voltage of the switching power supply, the lower the efficiency is, because the output loss of the output rectifier is inversely proportional to the output voltage;

Q: Computer host switch power supply how much money?: Switching power supply are generally in the chassis above the only bad repair

Q: Why should the switching power supply feedback the winding power supply?: Of course, you can use an external power supply to separate the power supply to the switch chip. But that way, the cost is high.
