- 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:In the use and installation of the regulator, what should be noted
- While the regulator to use and install, we should note the areas in which the following by the Westinghouse simply tell your face :( a) in contact with the regulator to ensure enough space to avoid running occurs when heat case; (b) put the regulator on the power distribution panel, choose the appropriate fuse, so as to ensure safe use of electricity; (c) either regulator, in Plug in all of the input and output lines Thereafter, the switch must first close and then open, the output voltage is normal after checking to ensure that, in order to re-open; (iv) the power output of the access surface of the electrical equipment, appliances to be noted that the value and the nominal value input of the regulator are the same, absolutely can not go wrong; (e) Remember that regulators are not overloaded used; when (six) have elected to use electrical equipment air conditioning, refrigerators have the motor running, you should select more than three times the capacity of regulators , to avoid the device starts regulator current exceeds the overcurrent protection fuse or circuit breaker current causes the current regulator is a blown fuse or trip a circuit breaker, or because of pressure drop Large and unable to work; (vii) after the regulator installed, first open the switching power supply, if the indicator lights work, then we first look at the indicated value of voltmeter is normal. Output voltage is normal, and then open the power supply power switch, the regulator can automatically adjust the voltage, the normal power supply. Westinghouse electrical professional regulator manufacturers, production voltage regulator, AC voltage regulator, CNC regulator, and so the power supply, the model is complete, welcome to buy!
- Q:How do I use a digital multimeter to measure current? Or how do you calculate the output power of your regulated power supply?
- When measuring the current to the meter in series in the circuit, that is, first disconnect the circuit and then disconnect the meter at both ends.
- Q:LM317 to do 0-24V adjustable DC power supply 80
- In this figure the adjustable R2 ground terminal access 1.25V negative voltage on the line friends. The The The The The The Other filter capacitor, then appropriate to adjust it
- 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:What is the current of the DC regulated power supply?
- Under normal circumstances, low-voltage DC power supply current will change with the resistance changes. That is: the voltage must be, the current resistance with the resistance of the regular changes in the resistance. To adjust the current, the regulator circuit is generally designed to adjust the regulator circuit.
Sometimes, DC power supply output unchanged, with electrical resistance is small, and do not want the resistance flow through a lot of current, I used three methods commonly used, one with thyristor to adjust the circuit, through the control of thyristor The current is generally suitable for the current requirements of the current is not high resistance circuit; the second is to use the transistor to adjust the circuit, by adjusting the transistor base current to adjust the current through the transistor ce set. 500mA below the small current with a class of C9013 C8050 can be a large current available 3DD102c like the tube, the maximum current 5A, can also use other transistors, according to the actual needs of choice. The third is to use adjustable voltage integrated circuits, such as LM2576-ADJ, LM317 and so on. In fact, by adjusting the voltage to adjust the current.
- Q:The main reason for the instability of the output voltage of the regulated power supply
- The main reasons are the following:
1. As the input voltage is unstable (usually AC power grid allows ± 10% of the fluctuations), resulting in rectifier filter circuit output DC voltage instability
2. As the rectifier filter circuit internal resistance, when the load changes, causing the load current changes, so that the output DC voltage changes
3. Since the parameters of the electronic components (especially the conductor devices) are related to the temperature, when the ambient temperature changes, the circuit component parameters are changed, resulting in a change in the output voltage
4. Rectifier filter obtained after the DC voltage will still have a small amount of ripple components, can not be directly supplied to those who require a higher power quality of the circuit.
Therefore, the rectified filtered DC voltage must take some voltage regulator measures to meet the needs of electronic equipment. Commonly used DC voltage regulator circuit with parallel and series voltage regulator circuit two types.
Above is the DC voltage regulator output voltage stability of the reasons for the simple analysis, we can combine the actual use of the situation to conduct in-depth analysis.
- 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:Is the switching power supply output from a regulated or pulsed power supply?
- The pulse width at both ends of the transformer lead varies with the load or the pulse width which varies with the load and then becomes the pulsating DC through the rectifying element and then the pulsating DC becomes the flat by the discharge of the capacitor DC voltage through the regulator circuit to ensure the stability of the output so the result is the power supply voltage regulator phone is not the same as most of the regulator is also a cross-flow function there is no regulator of the DC (this is the kind of transformer, But 50HZ AC transformer after the rectification of the basic) out
- Q:Design DC power supply,
- LM317 can output positive adjustable voltage
LM337 can output negative adjustable voltage
Both of these can meet your input voltage, output voltage range requirements.
