Q:Switching power supply CE certification is probably how much money
Switching power supply CE certification is not expensive, do a CE certification can be sent to the RoHS certification, the specific cost can provide product information to assess, package rectification, retest not charge, welcome to consult us CNAS laboratory, ID number is the phone, thank you!
Q:Switching power supply
Switching power supply is usually divided into AC / DC, DC / DC, DC / AC and other types. Popular is to convert a voltage into a specific voltage for the needs of electrical equipment. Such as car switching power supply is the car's 12V DC voltage into 5V or other voltage for the use of equipment. Commonly used mobile phone charger (also switching power supply), computer power and so are switching power supply.
Q:Car cd with the battery all right, with a switching power supply speaker has a buzzing sound
Recommended frequency transformer. Switching power supply is prone to interference, not easy to handle
Q:Is the switching power supply connected to the power supply voltage is too low on the switching power supply it?
How little, but not large, because the switching power supply is 110 volts or 220 volts input, but the output voltage is regulated output power, so no harm, do not worry
Q:Switching power supply, constant current power supply, resistance to the power supply where the benefits?
Capacitive power supply is a constant current power supply, the principle of its buck is the principle of "series circuit resistance divider law", the advantage is very low cost, the circuit is very simple, high efficiency in the case of constant load. It is more shortcomings, the first is the power supply circuit and its output is not isolated from the output, followed by the value of the voltage divider and the load current, not suitable for large changes in the load of the circuit (changes in efficiency will be reduced), not afraid Short circuit but fear of open circuit, and the power supply may be an instantaneous surge current, the surge current will flow through the load, it must be protected. The power factor of the circuit itself is very low.
Q:Is the DC input and AC input switching power supply available?
General low-power switching power supply input can be as low as 85VAC. Equivalent to 110DC, in the allowable voltage range should be possible.
Q:What is offline LED driver? Offline switching power supply
Offline LED driver is a circuit using EMI suppression circuit, rectifier filter circuit, paddle PFC circuit, AX2028 constant current system circuit to drive LED work, LED products to drive the power requirements include: stable, reliable, efficient, common. AX2028 is a constant current LED control chip, the system application voltage range of 12VDC to 600VDC, duty cycle of 0 to 100%, fixed off time mode of operation. It supports AC 85V ~ 265V input, non-isolated and isolated applications. AX2028 uses a unique technology for constant current control and compensation methods, the LED current in the exchange of 85V ~ 265V range of less than ± 3% .AX2028 using optimized system structure, making the system efficiency is higher than 92%. Can be widely used in E14, E27, PAR30, PAR38, GU10 and other lamp cups and LED fluorescent lamps.
Q:What is the problem with the switching power supply?
You better stick your PCB map, so you can see if your wiring is reasonable, the switching power supply is very particular about the wiring, In addition you can also on the power network, to the IW area post, you can get more professional guidance General safety requirements of the primary level in the board to the distance of more than 3mm, for a 7W switching power supply, the size of the transformer is certainly not large, 1 and 2,5 and 6 feet of the distance is certainly less than 3mm, unless your sub The output is flying
Q:Charger, switching power supply, power adapter these three different?
Charger, switching power supply, power adapter can (but not necessarily) is a thing, Switching power supply is to pay attention to the internal characteristics of the items, the charger is to pay attention to his use, power adapter is highlighted as the main equipment of the auxiliary. Such as ---- porcelain bowl --- switching power supply ------ refers to the bowl is made of porcelain       Rice bowl --- charger ------- refers to the use of the bowl (Note that the charger is not a switching power supply to do, rice bowl also has a glass bowl)       Tableware --- power adapter -------- refers to the service for the meal (power adapter also has a transformer AC output, the ordinary linear rectifier regulator output, as well as battery box. Tableware also has dish, spoon, etc. )
Q:How to change the switching power supply voltage?
In the 3V side plus a capacitor, positive and negative level can not take the wrong capacitor does not explode Oh, it is estimated that only to about 4.2V
Nowadays, our products are exported to numerous countres, like US, Australia, UK, etc. Successful improvements on technical processes and professional customer services have been recognized by more and more new or old customers. We hardly receive any negative feedback from customers. Our products so far have catched up with the consistency with world standard .
