Q:On the 1.2V DC power supply problem
The simplest is the diode buck, but the load current changes in the larger case, the stability is not too high. The best is to use MOS regulator for the regulator, the circuit is slightly more complex.
Q:DC power supply function is?
Output a stable DC voltage.
Q:DC power supply which parts of the composition of the various parts of the role of what?
In addition, DC power supply is mainly composed of four parts: power transformers, rectifier circuit, filter circuit and voltage regulator circuit.
Q:Ask, DC power supply in the middle of the GND is doing what?
Is a "ground" that is assumed for application. Exactly, it should be called "public".
Q:What kind of regulated power supply needs to be installed in the equipment room?
.. answer: the key is how the price? I said to you that the exchange of high-density power supply is not very understanding, if it is online UPS I think you have to consider the money in the pocket but also equipped with professional staff to deal with the daily maintenance of the problem Oh asked: do not maintain the installation On it, the main play a role in regulating the voltage answer: That being the case, then on it, I think your room to prevent the adverse effects caused by power failure? The original regulator can be asked: 7500W enough, right? Answer: This I am not easy to answer you, the best your own account of a computer's maximum power, and then multiplied by 30 to see if it is less than 7500W can, of course, the best redundancy
Q:What is AC regulated power supply
AC power supply is the AC power supply is stable AC power. DC power supply is DC power supply
Q:Why is the power supply in front of two capacitors, behind the two capacitors?
Large capacitor from the role of low-frequency filter, a small capacitor from the role of high-frequency filtering.
Q:What should I pay attention to when using a function signal generator and a DC regulated power supply?
When using the function signal generator, pay attention to the output signal from small to large, slow adjustment
Q:In the use and installation of the regulator, what should be noted
Second, the security matters ⒈ power supply in the power supply start, do not arbitrarily open the regulator power supply or pull the power supply input and output connections to prevent electric shock or other electrical safety accidents. ⒉ power supply input and output power supply must be arranged reasonable to prevent trampling worn, resulting in leakage accident. ⒊ power supply must be reliable grounding, due to non-ground wire operation caused by electric shock or human injury, by the user responsible for their own. ⒋ power supply can not be connected to the power line in the heating pipes, water pipes, gas pipelines and other public facilities, so as not to infringe the rights of third parties or cause harm. ⒌ should regularly check the power supply input and output connection, so as to avoid loose or fall off, thus affecting the normal use of power supply and safe power. ⒍ voltage regulator cable matching must meet the provisions of the current capacity to carry enough capacity of the cable. ⒎. Regulator should be gently, in the work of time to avoid severe vibration; ⒏, to ensure that the regulator of the carbon brush spring has enough pressure to avoid the carbon brush and coil contact surface flash; ⒐, non-professionals please do not open the regulator power supply or power supply for maintenance.
Q:I would like to ask: DC power supply when the ground terminal when used? how to use?
Ground (PE): not used for working circuits, only as a protection line. The use of the absolute zero voltage of the earth, when the equipment shell leakage, the current will quickly flow into the earth, even if the PE line has an open circuit, will also flow from the nearby ground into the earth   And then better, if it is a metal shell, to prevent electric shock; also can provide electrostatic discharge circuit   Connection: received three-core power supply on the ground, if there is buried copper pillars, then better in the above, because more pure
