Q:Will the adjustable power regulator what brand is good: Adjustable regulator power supply brand is good, this is good or good quality, or that the price is good?

Q:DC power supply design and production of what materials: The simplest constant voltage DC power supply requires the following materials: 1, transformer 2, rectifier diodes or bridge heap 3, filter with electrolytic capacitors 4, the regulator circuit (78 series of fixed three-terminal or adjustable three-terminal regulator LM318, LM338) 5, other needs of electronic components (resistors, light-emitting diodes, potentiometers, etc.).

Q:What is the DC power supply load characteristics of the curve, how to determine, good and bad What is the performance, if not good, how to improve it, please advise people: DC load power supply load curve, that is, the relationship between the output voltage and load resistance curve (the greater the resistance the higher the output voltage), is determined by the output power of the power supply itself. On the improvement that depends on what you do the circuit, and now the more popular is the switching power supply, is to control the duty cycle, the first output square wave, and then after the filter circuit. If you want to have a voltage regulator circuit, the feedback circuit is based on the load to adjust the power duty cycle. An electronic device that provides stable DC power for the load is called a DC regulated power supply. DC load power supply load curve, that is, the relationship between the output voltage and load resistance curve. Load (resistance value) The smaller the power, the output voltage is relatively stable, the load (resistance value is small) the greater the power, the lower the output voltage).

Q:DC power supply production: (3) lead wire shaping of electronic components When the electronic components are mounted on the circuit board, the pins of the components must be shaped in advance to accommodate the needs of the circuit installation. The lead forming of electronic components is mainly to make the installation of components to meet the size of the components on the printed circuit board mounting hole size requirements. (4) electronic components of the plug method ① the order of the pack: the first low after the high, the first small after the big first heavy light. ② identification of components: electronic components of the mark and color code should be up, in order to identify; horizontal plug-in numerical reading should be from left to right, and vertical plug-in numerical reading should be from the bottom up. ③ the spacing of components The distance between the components on the printed circuit board can not be less than 1mm; lead spacing is greater than 2mm. General components should be installed closely, so that components attached to the printed circuit board. Components meet the following circumstances should not be closely mounted, and need to float: A, axial lead need to be vertically inserted: the general components from the printed circuit board 3 ~ 7mm; B, large heat of the components (high power resistors, high power tube, etc.); C, heat after the performance of vulnerable devices (such as manifold blocks, etc.); ④ pay attention to the polarity of the diode, integrated circuit, electrolytic capacitor The circuit board due to fewer components, components of the installation order: diodes, resistors, potentiometers, electrolytic capacitors, electrolytic capacitors, integrated circuits in the order of installation. Before installation, pay attention to whether the component pin oxidation, the oxidation of serious components to be processed and tin.

Q:My home voltage instability in about 150 volts, what should be done to make the computer work properly, and do not hurt the computer? Installed power supply, or buy a regulator, or UPS installed. I heard that the regulator is not continuous power supply is not suitable for computer use! How can i do?: If you have a budget in the power of 1,000 yuan, then you can buy a domestic 1KVA online UPS, the basic solution to your current problems. If you feel that spend a little more money, then advise you to buy a servo-type regulator.

Q:? input for the 220V / 50Hz AC, the output DC voltage UO adjustable range: 30V ~ 36V; maximum output current IOmax: 2A; ? U2 from 15V to 21V, the voltage regulation rate of SU ≤ 2% (IO = 2A); ? output noise ripple voltage peak - peak UOPP ≤ 1V; ? with overcurrent protection function, the action current IO (th) = 2.5 ± 0.2A; Seeking to meet the above requirements of the switch regulator power supply models and drawings, the answer is satisfactory to the high score: you can go to Guangzhou Post Branch website point of view there is no model for your parameters

Q:DC power supply what brand of the better ah: See you want to simulate or CNC. And your budget, and the maximum voltage and current you want. Shenzhen wheat, Gu Wei, Eddie Si

Q:Design DC power supply, the need to output -5 ~ -8 V adjustable voltage, which regulator should be used, requiring input voltage of -11 ~ -15V: LM317 can output positive adjustable voltage LM337 can output negative adjustable voltage Both of these can meet your input voltage, output voltage range requirements.

Q:It is required to output 0-250V continuously adjustable AC voltage in the case of mains input fluctuation. The load is only one coil of 800 ohms, so the power consumption is very small. What are the recommended models? how's the price?: Your output frequency is not 50HZ, with variable frequency power supply, if the output frequency is 50HZ, with the regulator can be, the general election 1KVA can, the price of hundreds of good,

Q:Why does DC power supply trip every time? Can you explain the specific reasons?: It may be output short circuit or empty too small impact current too much can not stand
