Q:Processing center, Siemens CNC system 810D, manufacturers recommend a certain power supply with the regulator, or sometimes because of voltage fluctuations and problems, ask what brand of three would like to stabilize the power supply, can not use UPS, such as Hills, feasible The General power in about 15KW bar.

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

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: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:I have a 220v buck regulator output 12v power supply, how to calculate its output power? I measured with a digital multimeter output port voltage is 12v, and then transferred to the current block, directly to the meter measured power output port, did not show, is not the way to measure the current is not right? How to test specific Or there is no way to calculate the power of the power, I now know the voltage is 12v, but the current does not come out ah? Put away How do I know the power of my regulated power supply?

First, prepare a resistor (preferably the resistance wire, you can change the length of any), the resistance wire access circuit, measuring the no-load voltage and the ratio with the resistance wire voltage, constant adjustment of the length of the resistance wire, when the voltage is reduced by 10% , Measuring its current, this time is about the power of the full load power. Details can refer to the Chinese electronic DIY home of the relevant information

Q:AC power supply and DC power supply difference

AC power supply is the AC power supply is stable AC power. DC power supply is DC power supply

Q:Ultra-low voltage automatic power supply how to use

Answer: how much power is your load ah! Is there you sure that your regulator is not wrong? Just bought no see no problems, is it Asked: is a computer `` `nothing else` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` `` You can generally know that the regulator is not a problem

Q:Switch DC power supply is what it means

Commonly speaking, switching power supply is AC rectifier filter, and then through the crystal switch and a certain voltage regulator circuit, the switching transformer output high frequency voltage and current, rectified filter output stable DC power supply. "Best answer"

Q:There are positive, GND and negative, GND and negative connected together.

1, the power supply is the two output terminals to negative as a reference, you can think it is a positive power supply, with positive as a reference, it can be considered a negative power supply. 2, DC power supply refers to the ambient temperature, load size, input voltage and other factors will make the DC voltage regulator output voltage changes in the power supply. 3, the power supply of the classification of many methods, according to the type of output power supply DC power supply and AC power supply; according to the regulator circuit and the load connection is divided into series power supply and parallel power supply; The working status of the tube is divided into linear power supply and switching power supply. According to the circuit type, there are simple power supply and feedback type power supply. 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 (only about thirty words is briefly summarized)

1, the grid input voltage instability 2, the load changes formed 3, the regulator itself to promote the conditions 4, components due to temperature, humidity and other environmental impact And change its performance
