Q: DC power supply, no load and load, the output voltage change it: But in the request is not high, you can think that the two are the same, or how the function of the regulator it?

Q: Will the DC power supply and DC constant current source of the respective characteristics: First, the DC power supply characteristics: 1, DC power supply output display: the output voltage and current LED display; 2, DC power supply using 19-inch standard size, can be combined to put in a variety of work platforms and racks; 3, small size, light weight, energy efficient; 4, constant voltage constant current: the output constant voltage constant current automatic switching, voltage and current values ??of continuous linear adjustment; 5, protection: overvoltage protection, overcurrent protection, over temperature protection, undervoltage protection, overload protection; 6, short circuit characteristics: the machine working state for a long time short circuit; 7, external compensation: the machine optional external compensation, can reduce the output loop due to a longer pressure drop; 8, overvoltage protection value: the output over pressure protection value can be protected, cut off after the protection output and lock, re-boot recovery; 9, communication function: optional special data interface, and other equipment data connection control, or with the PLC connection; 10, DC power supply external control function: optional 0-5V or 4-20mA signal control power supply output voltage and current; 11, a timer function: optional timer switch function.

Q: Need a circuit, marked the size of the components, it is best to have a detailed calculation process. The circuit diagram can be viewed under MULTISIM Or send something to my mailbox Do good cash reward: LM317 voltage output range is 1.25V ~ 37V, 1.25V below can not guarantee. Circuit diagram is as follows, the voltage calculation formula Iadj is very small (50μA) can be ignored, the potentiometer resistance selection 4.7kΩ can meet the output voltage 1.25V ~ 24V adjustment range.

Q: DC power supply technical indicators which: 3, the limit index (1) the maximum input voltage Is to ensure that the DC power supply safe operation of the maximum input voltage. (2) the maximum output current Is to ensure that the safe operation of the regulator to allow the maximum output current.

Q: The difference between the series DC power supply and the parallel DC power supply: The main difference: parallel DC power supply / low efficiency, especially when light load, the power is almost all consumed in the current limiting resistor and adjust the tube; * Output voltage adjustment range is very small; stability is not easy to do very high. The series power supply is just to avoid these shortcomings, so now widely used are generally series power supply.

Q: BEC (UBEC) and adjustable buck regulator power supply is different: The main heat from the regulator, the real control of the motor MOS switch in fact heat is not large) because of its efficiency is not high, the natural output current can not be large, the general maximum of 1A or so

Q: What is a linear regulated power supply: Here the linear regulator power supply, refers to the adjustment tube work in a linear state of the DC power supply. Adjust the tube to work in a linear state, so to understand: RW (see the following analysis) is continuously variable, that is linear. And in the switching power supply is not the same, switch (in the switching power supply, we generally call the tube called switch) is working in the open and close the two states: open - resistance is very small; off - resistance is Big. The pipe in the switch state is clearly not a linear state. Linear regulated power supply is a relatively early class of DC regulated power supplies. Linearly regulated DC power supply is characterized by: the output voltage is lower than the input voltage; fast response speed, low output ripple; low noise generated by the operation; low efficiency (now often see the LDO is to solve the problem of efficiency problems) ; Large heat (especially high-power power), indirectly to the system to increase thermal noise

Q: Who bought a computer, but in the case of uninterrupted power is always automatically shut down, and later heard that my family away from the transformer far, voltage instability, then I bought a regulator, but the effect is not very good, There is still a power outage, and some people say that to buy a power supply, I do not understand the function between the two and the difference, please master answer!: Only AC voltage regulator, if this is not, buy a UPS, open the computer when the inverter, do not open the time, the battery charge.

Q: Power supply KA7805 how to judge good or bad: All 7805 are LDO (linear power supply), especially with a heat sink, 3 feet, so all xx7805 chip can replace it, as long as the package (physical size) the same. Such as LM7805, MIC7805, AS7805, AIC7805, LT7805, etc., the first two letters that different manufacturers, the same function. 7805 regulator ordinary chip, all the electronic market has. Its role is to 6.5V ~ 15V or so the input voltage is reduced to a stable +5 V voltage.

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.
