Q:What is a linear regulated power supply

Here the linear regulator power supply, refers to the adjustment tube work in a linear state of the DC power supply. Adjust the tube to work in a linear state, so to understand: RW (see the following analysis) is continuously variable, that is linear. And in the switching power supply is not the same, switch (in the switching power supply, we generally call the tube called switch) is working in the open and close the two states: open - resistance is very small; off - resistance is Big. The pipe in the switch state is clearly not a linear state. Linear regulated power supply is a relatively early class of DC regulated power supplies. Linearly regulated DC power supply is characterized by: the output voltage is lower than the input voltage; fast response speed, low output ripple; low noise generated by the operation; low efficiency (now often see the LDO is to solve the problem of efficiency problems) ; Large heat (especially high-power power), indirectly to the system to increase thermal noise

Q:What is the solution for a regulated power supply?

AC power supply voltage fluctuations in the main situation of the following two points: (1), the voltage fluctuated, can not be stabilized within the scope of the standard voltage permit; (2), the voltage continues to be high or low. The above two cases for the safety of electricity and electrical safety are a lot of unfavorable factors. With long-term work in such a voltage environment will cause air consumption increases, increased current consumption, reactive power is high, a serious rise in temperature, electrical appliances can not work properly and so on. More serious will burn the electrical, and even cause a fire!

Q:What is the role of power supply regulator?

Computer chassis components are "vulnerable" accessories, voltage instability easily lead to the motherboard graphics card burned, so there is a stable power supply, you can maximize the stability of the input voltage to maintain the power output voltage is constant, so that the computer The host is not easy because of voltage instability damage!

Q:AC power supply and DC power supply difference

AC power supply is the AC power supply is stable AC power. DC power supply is DC power supply

Q:I have a computer power supply, how to use it to change the power of other electrical appliances? 12V.5V must be. It has a lot of lines above, what color represents what the meaning? And then why is I connected to the power after the basic line basically no voltage output? Is there a thread that controls the output of the power supply?

5, PS-ON (green line): Responsible for the operating system management power switch, is a motherboard signal, and + 5VSB together referred to as soft power. Less than 1V when the power is turned on, greater than 4.5V when the power off, the realization of software switching machine, the network remote wake-up function (set wake-up time, through the keyboard boot) (and GND then short-circuit can start the power supply) 6, -5V (white line): (Negative voltage rarely used, such as SFX removed -5V) 7, -12V (blue): PG signal (Power Good, gray line, + 5V signal (+ 3.0 ~ + 6.0V)): before the system starts, the power supply (0.1 seconds to 0.5 seconds after the power is turned on to issue the signal) for internal inspection and testing, To the motherboard a signal, so the power is controlled by the power supply on the motherboard monitoring components. PG signal is very important, even if the output is normal, if there is no PG signal, the motherboard still can not work; if the PG signal timing is not right, will open the machine.

Q:Maintenance of mobile phone power supply is best used to what

Switching power supply small and exquisite, but the ripple is relatively large.

Q:From the old computer to remove a switch power supply can do what, can be used when the power? how to use?

Yes, mainly whether the power supply is sufficient. Voltage and current are appropriate. Use: find a green line of power output to the green line to the ground to switch power to work. Can also be connected to a switch to facilitate the switching power supply switch.

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:DC power supply, no load and load, the output voltage change it

But in the request is not high, you can think that the two are the same, or how the function of the regulator it?

Q:Switching power supply and ordinary power supply compared to what advantages

Advantages: (with power ratio between) small volume Power is large efficient flexible
