Q:Use 7812 to make a positive 12V DC power supply
If the transformer secondary symmetrical center tap, with full-wave rectification, then the secondary voltage can also be set lower, 11.5V ~ 12V can be.
Q:When the power supply is used, pay attention to what
"1. Check the power input and output terminals for short circuit phenomenon. 2. Look at the chassis rear panel fuse holder inside the fuse is installed
Q:DC adjustable power supply DC adjustable power supply manufacturers which is good?
Honghai Electric to the results as a new starting line, adhere to independent innovation, scientific development, take the market, brand, technology, production, personnel, management, capital internationalization of the road, and strive to build a red sea electrical power into a strong competitive enterprises.
Q:How does the power supply protect all electrical appliances at home?
Hello there! You said the function requires two machines to complete: 1, the regulator: the external network input voltage is stable at the standard mains voltage of about 220V device. Installed in your home meter behind you can protect all the appliances. Power grid voltage is too high, beyond the upper limit of household appliances design, household appliances can not withstand the high voltage and the possibility of damage. The grid voltage is too low, the starting current of the electrical appliances will be low starting voltage, start the current is small and can not start normally, serious may make it long in the start of the high current state and damage the core components. 2, uninterruptible power supply (UPS): is to give your appliances to provide an uninterrupted power supply, such as power failure when your computer is not a power outage to eliminate the illegal shutdown caused by unnecessary losses. Due to power constraints, can not receive high-power appliances, in fact, no need to pick up other electrical appliances, only connected to the computer just fine.
Q:AC purification power supply buzz sound is great what is the situation
Repair, as long as the tightening of the regulator around the core of the fastening screws can be. At the same time to tighten the components around the regulator to eliminate or reduce the vibration sound.
Q:How to describe the power supply voltage accuracy
stability For example, there are 100 dollars to be distributed to 7 individuals assigned to the accuracy of 1% in terms of the proportion of money that is to say the exact value of the yuan points to reach the points
Q:Classification of DC Regulated Power Supply
There are many kinds of power supply classification methods, according to the type of output power supply DC power supply and AC power supply; according to the regulator circuit and the load DC power supply connection points are connected in series power supply and parallel power supply; According to the working state of the regulator tube with 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. So many of the classification is often so that beginners puzzled, do not know where to start. In fact, it should be said that these seemingly a lot of classification between the methods have a certain level of relationship, as long as the level of this level can naturally distinguish the type of power.
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:What is the switching power supply?
"Switch-type power supply" and "tandem-regulated power supply" compared to energy efficient; to adapt to the power of change; strong output voltage adjustable range; a switch can easily get multiple sets of different voltage levels Power supply; small size, light weight and many other advantages, and was widely adopted.
Q:DC power supply design and production of what materials
Okay, yes. N the contents of the full to give.
We are committed to provide high quality products and services to meet diverse customer requirements and diverse market requirements. With the same diligent customer-oriented spirit, we are dedicated to continuously designing, manufacturing, marketing, and introducing our products to the diverse demanding power market.
