Q: Power supply to the Mori Chong 86N power supply 24-70 volts At present, the use of a 350-watt 50V switching power supply, the maximum current of 7.3 Motor dial selection current 6.3A, short-term operation, heat is not large At this point the switching power supply fan does not turn - is not long-term operation or power to increase the heat when the fan will start? Or are the fans running anyway? So that is the switch power supply cooling fan is broken?: Look at your fan a few lines, two words, do not turn is bad, or broken

Q: A DC / DC switching power supply input with UC3843 is a 24V power supply between two power supplies is up to 200M line now the situation is DC / DC power supply at no time when the load is measured at this time DC / DC power input It is actually less than 15V if the DC / DC power supply is loaded with about 10W and the 24V power supply output is adjusted to 27V or more when the DC / DC power supply is working In front of the wrong In the load when the 10W when the front power output is adjusted to 27V measured when the power input voltage is 14.5V or so when the no-load time is normal add another point With 10W when the front of the power output is adjusted to 27V below the two power between the current is significantly increased at this time into the DC / DC power supply voltage from 15V down to 6,7V looks more like the back of the power from Excited and DC / DC of this power supply in the 9V or so input conditions can work properly: DC / DC no load when the input less than 15V? Look at the 24V power output is how much, if it is 15V instructions that the power supply voltage is not correct, otherwise it is DC / DC no-load power is too large

Q: Give you a switch on how to look at it is isolated and non-isolated?: General low-voltage direct current is mostly non-isolated, high-voltage communication for the isolation

Q: Wireless communication room in the combination of switching power supply and integrated switching power supply and the difference between the respective functions?: The so-called combined switching power supply, there are a number of independent switching power supply through the switch with control cabinet control, according to the size of the load to the wireless communication equipment power supply, load can provide two or more switching power supply, Taiwan power supply. And the integration of the power he is a wireless communication equipment to form an integrated device, can only have the equipment to accompany the switching power supply. After the switching power supply is damaged, the communication equipment than to stop working, the combination of power can be changed for other power supply

Q: Why should go through the cross - straight - pay - straight conversion, rather than directly after the transformer buck after rectification, filtering, switching power supply is not a way to reduce costs? Parallel power supply is significantly better than switching power supply, why no one tried to do one?: Just for the boot convenient, do not switch how you boot? Shut down the general use of the system off. Power on the shutdown is a longer process. A part of a part of the start off. More details later say

Q: What is the difference between an open switching power supply and an ordinary switching power: DC switching power supply, its function is to the power quality of the poor quality of the original ecological power (coarse), such as mains power or battery power, to meet the requirements of the equipment to meet the higher quality DC voltage (fine). DC switching power supply is the core of DC / DC converter. So the DC switching power supply classification is dependent on DC / DC converter classification. In other words, the DC switching power supply classification and DC / DC converter classification is basically the same, DC / DC converter classification is basically DC switching power supply classification. DC DC / DC converter between the input and output whether there is electrical isolation can be divided into two categories: one is isolated as an isolated DC / DC converter; the other is no isolation called non-isolated DC / DC converter.

Q: Teacher asked, I said that can improve power efficiency, there are small size and high efficiency characteristics. What else does it mean? For example, in the control of the characteristics of: High-frequency switching power supply oscillation frequency is generally tens of KHZ, is relatively low 5050 in terms of ordinary frequency. "High frequency" is the higher frequency, refers to the number of times per second oscillation to high-frequency switching power supply dedicated chip TL494, its reference oscillation frequency of 25KHZ, frequency than the traditional 50HZ power 500 times higher.

Q: AC-DC switching power supply, how to connect, input AC, AC, FG three ends: Input AC, AC, respectively, then the power line FireWire, zero line, pay attention to view the two input terminals, preferably the power of the internal fuse connected to the other end of the line connected to the other end of the line, the fire line can also be connected to the normal line. FG ground wire.

Q: I made a switching power supply, using boost dc-dc transform, input 18V, output 30-36V variable. Found that the output voltage has 300mv ripple and 1V burr. Has been added 10mh inductance and 6600uf capacitor filter. Switch tube plus RCD buffer Output with choke and EMI filter,: Low frequency ripple burr suppression of several commonly used methods: A, increase the output low-frequency filter inductance, capacitance parameters, so that low-frequency ripple reduced to the required indicators. B, using feedforward control method to reduce the low frequency ripple components. High-frequency ripple to suppress the purpose of the glitch is to provide high-frequency ripple path, commonly used methods are the following: A, to improve the switching power supply operating frequency, in order to improve the high frequency ripple frequency, is conducive to suppress the output high frequency ripple. B, increase the output high-frequency filter, can inhibit the output high-frequency ripple. C, using multi-level filtering.

Q: Computer host switch power supply how much money?: Depending on the brand and power, the price is different New 230W about 60-100 or so 300W about 100-200 or so 400W about 150-250 or so
