Q: Switching power supply COM how to connect: Generally grounded. The The The The Specific instructions, marked

Q: High power high frequency switching power supply with what rectifier: Such as high-power charger on the use of this switch is suitable for high-power.

Q: Neighborhoods! Control transformer and switching power supply of the difference, for occasions, advantages and disadvantages: Control transformer output for multiple groups of AC, usually AC: 36v, 24v, 12v, 6.3v, mainly for the lathe control system and some other need 36v coil voltage control occasions; switching power supply also has multiple output, but the output is After the DC voltage regulator, usually DC: 48v, 24v, 12v, 5v, 3.3v, etc., mainly used for some need more than one DC power supply place, such as: the computer power supply is more than one group of DC output switching power supply, It has 12v, 5v, -5v, 3.3v and other sets of output; electric bicycle battery charger is the switching power supply, usually the output DC voltage of 48v DC, used to charge the battery, there are 24v.

Q: What is the relationship between the output voltage of the switching power supply and the PWM signal?: First of all, what is your circuit topology? Is BUCK, or isolated rebirth is it? Different circuits, the answer to your question is different. However, a large range can be explained as such. The larger the PWM duty cycle, the stronger the output load. (That is, the output voltage * the greater the output current.) You better, or look for the corresponding topology of your circuit information, find the formula, so good to understand some.

Q: Switching power supply where to buy? Is there a recommended shop?: Hello, I am selling switch power, but do not know what kind of power you want, where people are. Please ask.

Q: Switching power supply (AC-DC) use notes and tips: Power Usage Precautions: First, the metal shell Power cord and the shell is generally connected with the ground (FG), to be reliable grounding, to ensure safety, can not be mistaken to the shell connected to the zero line. ??Second, before the installation is complete power test run, please re-check and proofread the wiring on the wiring, make sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current value is correct Before they can run. ??Third, for high-power LED switching power supply, there are three or more than three "+" input terminals and "-" output terminals, in fact they belong to an output electrode, just to make the user easy to connect, and multiple terminals Respectively, in the internal and then together.

Q: What is a linear adapter and a switching power adapter: Linear adapters and switching power supplies are commonly referred to as linear power supplies and switching power supplies. Linear power supply refers to the power of the regulator tube work in a linear state, while the switching power supply regulator tube to work in the switch state.

Q: "First AC into DC, and then into a higher frequency of alternating current through the high-frequency transformer voltage conversion" Why? "LED display as a high-precision instrument to select the switching power supply instead of the transformer" Why?: Switching power supply and the difference between the transformer is a very stable switching power to a certain range of voltage into a very low voltage or high voltage (such as 110V-250 input, the output voltage can be stable control in the required voltage plus or minus 0.5 V)! Transformer output voltage is changing with the input voltage, that is, the input voltage increases the output voltage is also increased, the input voltage to reduce the output voltage is also reduced. Because the switching power supply is the first AC into DC, DC power through the power switch and then become a higher frequency of alternating current through the high-frequency transformer voltage conversion is not only efficient and high frequency after the greatly reduced the volume, but also save the copper and iron loss. Because the switch is controlled by the power switch, the switch is turned on for a short time and the output voltage can be maintained. When the load is large, the switch keeps working to keep the output voltage. So the switching power supply output voltage is stable, can be used as LED display and other high-precision instrument selection.

Q: I went to the hardware store and mobile phone shop asked the next, said that there is no such thing: Personal recommendations do not buy, directly connected to the line with a plug switch to control the cat's power switch.

Q: Switching power supply, Fairchild Semiconductor's switching power supply chip data, the application of the chip design switching power supply can be divided into two categories: Adapter and Open Frame, and the general application of the former Adapter mode design power than the latter will be large The What kind of structure or type, what is the difference between the two?: That is, network power switch. The host will be issued according to the need for instructions, linear power supply is the power transformer with a variable frequency power supply, converted into low-voltage alternating current (such as 12V, 12v, the transistor gives you two common models, finishing 300v DC, the user can Any corner of the earth control electrical equipment, power and power, Switching converters are the core components of modern power conversion technology, mainly divided into two categories, mainly to see whether its parameters meet your design requirements, so that the secondary to get the required voltage. .. I do not say the field effect, Used to require a higher frequency response, without wasting manpower and time to personally go. Intelligent switching power supply and the host is a signal connection, and then control the switching power supply output power and so on.

We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
