Q:Switching power supply CE certification is probably how much money
CNAS laboratory, TUV ITS UL witnessed laboratory. Switching power supply CE certification, to do LVD + EMC, LVD pay attention to temperature and pressure, EMC attention to conduction radiation. See ID is the mobile phone number
Q:What is the relationship between the output voltage of the switching power supply and the PWM signal?
Brother ~ ~ give you advice ~ ~ power problem is not so good ~ ~ ~ Switching power supply output voltage is controlled by the PWM duty cycle to achieve the adjustment ~ When the pulse width, duty cycle increases, the output voltage increases, otherwise ~ ~
Q:How to choose the switching power supply frequency?
such as 300KHZ better magnetic material can do 500KHZ or more high. Input voltage and then higher, we need to pay attention to the switch tube switching loss problems, and generally only to do dozens to hundreds of hundreds of KHZ or so. The specific circumstances of the specific analysis, and some soft-switching, resonant what the high-power high-efficiency topology!
Q:What brand of switching power supply cost-effective?
See what kind of switching power supply, LED, or industrial use, or communication.
Q:12V switching power supply, which brands through 3C certification?
3C certification is China's mandatory product certification, where the directory in the 3C certification required to be certified products need to be certified to the factory sales, import and use in business activities. The PC power supply belongs to the directory to be mandatory certification of products, so in the market of formal power products will be mandatory through the 3 C Such as HuntKey, Colorful, Great Wall, GOLDENFIELD, TT and Cool Cold's mainland sales products.
Q:Led lights switching power supply controller how to repair
If you just use it alone, it's broken. It is recommended to buy one. Because the maintenance needs to change the device, and their purchase of equipment is expensive, and can not determine that the device is bad. If you are learning to repair, it depends on the principle of switching power supply. Principles of understanding, the manufacturers work, maintenance is very simple.
Q:Switching power supply where to buy? Is there a recommended shop?
It is recommended not to go to the electronic market, to buy the words can go to 21 sites, or apply for samples
Q:The main function of the communication switching power supply is
Do not know the exact meaning of your problem. We usually talk about the communication with the switching power supply is rated at 48V DC power supply. Power in any circuit, of course, is to its power supply, like a telephone, the phone's two lines are rated at 48V DC, no load up to 60V. Communication also through the send, receive, and intermediate processing process, the processing of the chip ah these are also need to supply the thiophene.
Q:What is the linearity of switching power supply
Different power supply, linear adjustment rate is different Constant pressure source: Linear adjustment rate: the rate of change of the output voltage within the specified input voltage range; ΔV / V = (V - V1) / V * 100% Load rate: change in load within the specified range, change rate of output voltage; ΔV / V = (V-V1) / V * 100% A constant current source: Linear adjustment rate: the rate of change of the output current within the specified input voltage range; ΔI / I = (I - I1) / I * 100% Load regulation: change in load within the specified range, change rate of output current; ΔI / I = (I-I1) / I * 100%
Q:Why the computer to use switching power supply
1: Because the transistor can only work in the DC environment. So the first power into a DC and then through the shock circuit (oscillation frequency of 30 ~ 50KHZ) shock coupled with the required voltage. Coupled voltage is alternating current, so it should be collated into the DC power supply circuit.     2: Transformer and switching power supply comparison. Coupling circuit in the high-frequency environment than the efficiency of the transformer efficiency, so the switching power supply transformer can be done very small. The cost of switching power supply is indeed much lower than the cost of the transformer, and small size, light.      3: switching power supply elegant range is very large, good switching power supply can change in the 100V power grid in the normal work, if the grid voltage down to 150V or even lower, the transformer I am afraid you can not output the required voltage The Computer on the voltage requirements are very high, once the voltage changes will work unstable or even crash, hardware burned. Switching power supply can be very convenient to use the computer to control the open, shutdown, in the shutdown state, the power output only 1V voltage to the motherboard to do control signals, other such as 12V, 5V and other circuits are not working. So more power. In summary: switching power supply is the best choice for the computer.
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.
