- Q:How to determine the power of the power supply
- Is sure to consider the need to see the actual power of your load to determine.
- Q:Ask, DC power supply in the middle of the GND is doing what?
- In the electronic circuit, that the ground.
But this "land" is not the true sense of the land.
- 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:Power supply KA7805 how to judge good or bad
- KA7805 a total of 3 pins, the input pin plus 9V voltage, measuring the output pin is 5V. Ground pin shared.
- Q:Power supply 4.5v can drive 3.6v lithium battery
- it is recommended:
1, carefully measure the output voltage of the regulated power supply.
2, if it is 4.5 volts, easy to transform the output can be connected to a "germanium diode" (its forward conduction voltage is 0.2 ~ 0.3V), will make the output voltage is basically reduced to the appropriate.
- Q:Switching power supply and DC power supply difference
- DC linear power supply is relatively heavy, filter capacitor head large, the overall volume. DC linear power supply is to adjust the tube divider to reduce the output voltage, so the burden of regulating the tube is heavy, heat and efficiency is low. But the dynamic response is very good, suitable for changes in load more frequent places, such as audio amplifier.
Switching power supply is relatively light weight, smaller size. Switching power supply is through the switch on and off the number of times or time to adjust the output power, efficiency than the linear power supply is higher, relatively small amount of heat, but the dynamic response is poor, suitable for more stable load place. Switching power supply filter capacitor due to the high frequency, so the interference of the power grid is very large.
- Q:DC power supply is linear or switch
- DC power supply with a linear power supply, but also switching power supply.
- Q:What is the solution for a regulated power supply?
- There are three reasons for the problem of supply voltage.
1) power plant generator regulator device problems, resulting in fluctuations in output voltage. Such are generally small hydropower stations.
2) substation or distribution station power transformer performance problems, especially in disrepair aging serious.
3) The total electricity consumption in the area is much higher than the power supply load, resulting in the supply voltage is low, serious and even the frequency of power supply will be low so that the power grid paralyzed a large area power outage!
- Q:The difference between the series DC power supply and the parallel DC power supply
- There are many ways to classify the regulated power supply, and the DC power supply and the AC power supply are connected according to the type of the output power supply. According to the connection mode of the voltage regulator circuit and the load, the series power supply and the parallel power supply are connected. Working conditions are divided into a linear power supply and switching power supply; according to the type of circuit is divided into a simple power supply and feedback power supply, and so on. DC power supply specifications can be divided into two categories: one is the characteristics of indicators, reflecting the inherent characteristics of DC power supply, such as input voltage, output voltage, output current, output voltage adjustment range; the other is the quality indicators , Reflecting the advantages and disadvantages of DC power supply, including stability, equivalent resistance (output resistance), ripple voltage and temperature coefficient.
- Q:Siemens CNC system 810D what regulator power supply good? Or is it good?
- Can be, but you can only estimate a larger UPS or power supply if there is no time to ask the proposed power supply with a good cost savings
