Q: What is the regulated power supply?: Is a constant voltage power supply, can be AC, it can be DC, according to the needs of different voltage regulator is not the same.

Q: What is the meaning of the regulator accuracy?: The regulator is a device that stabilizes the output voltage. Regulator with constant voltage regulator, control circuit, and servo motor and other components. When the input voltage or load changes, the control circuit for sampling, comparison, amplification, and then drive the servo motor rotation, so that the regulator carbon brush position changes, by automatically adjust the coil turns ratio, thus maintaining the output voltage stability. Regulator accuracy refers to the output voltage fluctuation range is smaller, the higher the accuracy, such as electricity is very unstable, about what low, high precision regulator can be controlled within a safe range, like the computer this Precious equipment requires high precision.

Q: Is it possible to power the regulator and the regulator? Please enlighten me: A regulated power supply is an electronic device that provides stable AC power or DC power for the load. Including AC power supply and DC power supply two categories. Regulator, as the name implies, is to stabilize the output voltage of the device. All regulators use the same technique to achieve a stable output voltage of the output voltage through a voltage divider connected to the inverting input of the error amplifier, and the non-inverting input of the error amplifier is connected to a reference voltage. The reference voltage is generated by the bandgap reference inside the IC. The error amplifier always tries to force the input at both ends to be equal. To this end, it provides the load current to ensure that the output voltage is stable.

Q: From the old computer to remove a switch power supply can do what, can be used when the power? how to use?: can! As long as the power is enough!

Q: What is the use of negative pressure power supply output negative pressure: It depends on how you use it! General amplifier circuit used more. Digital display direct measurement, black pen then the public, red pen were positive and negative ends. When the negative value is displayed, the "-" sign is displayed at the front of the header. When the pointer is connected to the same value, the red pen is connected to the common terminal.

Q: Switching power supply with load capacity difference is what reason. My switching power supply output is 2A-24v. The output is not connected to the output is 24v. Connected to the 24v -5w lamp only 2v voltage. Even the switch power indicator light is not bright. What 's the matter?: Switching power supply is very dangerous, driven load capacity is poor, if the circuit is no problem, that is, the capacitor problem, you can replace, and pay attention to dangerous ah

Q: The circuit teacher said the capacitor can not be 10uf, should not the same! Specifically did not say, ask the big god say, the specific capacitor should be how much ah! Check a lot, not found! Thank you!: This is nothing to calculate, are experience only. In addition the other two capacitors on the right is generally a electrolytic capacitor (large capacity) +1 non-polar capacitor (small capacity), to improve the high-frequency power output characteristics

Q: My home voltage instability in about 150 volts, what should be done to make the computer work properly, and do not hurt the computer? Installed power supply, or buy a regulator, or UPS installed. I heard that the regulator is not continuous power supply is not suitable for computer use! How can i do?: The regulator is the mains of the fluctuations to make it stable in the 220v, ups generally have this feature and when the power outage can also provide a few minutes to tens of minutes ranging from backup power, to the computer left to save and shut down time. No matter which of the two of your host power supply should be better quality, which will be directly related to the system is stable.

Q: It was strange to see a regulated power supply consisting of the op amp LM308A and the PNP transistor 2N2905. The output of the op amp does not return to the base of the transistor as usual, but returns directly to the inverting input of the op amp. The base of the transistor is connected to the positive voltage input of the op amp, connected by a resistor and the positive pole of the power supply. Do not know the working principle of the circuit, the role of the transistor, the output voltage regulator is how to adjust, do not know where the source of the circuit? I hope you experts advise!: I was the first time I saw this structure, I understand this: LM338 - 5.0 is a precision 5V voltage reference, the dynamic internal resistance is very low, the typical value is 0.6Ω, op amp LM308 is the emitter follower connection, 2,3,6 feet equal, that is, V2 = V3 = V6 = 5V, Rs and triodes constitute a parallel regulator circuit, and the op amp is the controller. Vin ↑, V3 ↑, V6 ↑, Io ↑ (op amp output current), I7 ↑ (op amp supply current), Ie ↑, URs ↑, Uout ↓.

Q: It is required to output 0-250V continuously adjustable AC voltage in the case of mains input fluctuation. The load is only one coil of 800 ohms, so the power consumption is very small. What are the recommended models? how's the price?: Your output frequency is not 50HZ, with variable frequency power supply, if the output frequency is 50HZ, with the regulator can be, the general election 1KVA can, the price of hundreds of good,
