Q: Recently to do the regulator business to our factory to sell, I would like to ask why the CNC machine tools installed voltage regulator? Not installed? what is the benefit? Please elaborate on the point!: CNC machine tools need to install the regulator. 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 is a can automatically adjust the output voltage of the power supply circuit or power supply equipment, its role is to fluctuate and reach the electrical equipment requirements of the power supply voltage stabilized in its set value range, so that a variety of circuits or electrical The device can operate normally at rated operating voltage. The initial power regulator is based on the relay's jitter stabilized voltage. When the grid voltage fluctuations, the power regulator automatically corrects the circuit to start, so that the internal relay action. Forcing the output voltage to remain near the set value, this circuit has the advantage of simple circuit, the disadvantage is the regulator accuracy is not high and each relay jitter shift, will make the power supply instantaneous interrupt and spark interference.

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: My graduation thesis needs, as long as 40 words is enough!: With the rapid development of today's society, the application of electronic systems is becoming more and more extensive. Electronic equipment has become an indispensable part of people's daily work and life. As the heart of electronic equipment  power system to the electronic equipment to provide the necessary energy  plays a vital role. Power system Good security and reliability is an important guarantee for the normal operation of electronic equipment.

Q: Why is the DC regulated power supply connected to the load circuit after the voltage is reduced: 1, the access load exceeds the actual power supply capacity of the power supply; 2, the power supply design problems: drive the drive force is insufficient, the base injection current is too small, the capacitor capacity is too small, etc.: 3, circuit parts have problems, resistance deterioration, transistor aging, etc.: 4, the AC power supply voltage is too low, AC low voltage side voltage is lower than the required voltage, etc.: 5, the transformer power is too low - inadequate.

Q: Members help me to explain the role of the various components in detail. The There D5 regulator is 21V why the output is 20V, they said to reduce the UBE0.7V pressure drop. I do not understand, why should subtract UBE ah? The more detailed the higher probability of adoption. The Remember the details. The The Thank you all the teachers. The ? Mainly three-tier tube is how to complete the regulator?: First, you have to know that the VT working state is in a magnified state or a saturated state, so VT's Ube> 0. VT is in magnified state, Ube = 0.7v. D5 to ground voltage (ie VT base voltage) = VT Ube + circuit output voltage Uout Uout = Ud5-Ube = 21v-0.7v

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: What is the current of the DC regulated power supply?: DC regulated power supply current do not tune! Only regulator does not transfer flow! DC constant current power supply voltage do not tune! Only flow regulator is not pressure!

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: What is the main purpose of DC power supply?: General DC power supply for capacitors, relays, resistors and other components for sophisticated, test use, but also as a thermistor, motor and other electronic components experimental test use. With high accuracy, high accuracy, high stability and other excellent electronic properties.

Q: Why Capacitor Filtering in DC Regulated Power Supply: Large capacity capacitor or energy storage components! Can improve the power of the power load performance! The same can also short-circuit return residual high frequency And AC signal!
