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?: Three words, that is, automatic temperature control, to the temperature to a certain extent will turn

Q: I do not understand the transformer should only work in the alternating voltage, but the switching power supply to the PWM IC output terminal connected to the primary input PWM IC has been rectified filter DC. Is the PWM modulation obtained by the high frequency of the exchange?: 2, PWM (pulse width modulation) is higher than 50Hz frequency, so that the transformer can be smaller, and the work efficiency will be greatly improved.

Q: What is a linear adapter and a switching power adapter: Linear adapters and switching power supplies are commonly referred to as linear power supplies and switching power supplies. Linear power supply refers to the power of the regulator tube work in a linear state, while the switching power supply regulator tube to work in the switch state.

Q: Switching power supply 220 / 24V input break can be frequent power off: Design has a project, but look at your off time.

Q: How to choose the switching power supply frequency?: Have a few points! The size of the input voltage, the choice of transformer magnetic material, the choice of the main switch tube, there is the overall volume requirements can also be said to want to achieve the power density! For example: low-voltage input, such as 6-160VDC, when the pressure on the tube is not high, the switching loss is not dominant, the frequency can be relatively high,

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: Switching power supply life is generally how long?: Now the earliest imported color TV has been more than 20 years, individual families have used to prove that switching power at least in more than 20 years. Of course, quality is not qualified in this column.

Q: UPS and switching power supply what is the difference: China's household appliances operating voltage is AC 220V. UPS and switching power supply main difference is: UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption. Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.

Q: Today encountered a switching power supply, independent of the 220v into, 12v out, after opening and ka3842 see the sixth foot of a resistor and a diode at the obvious phenomenon of burning, I measured with a multimeter has 300v, but a flash Flash After the resistance, the low pressure at a light is flash, no output,: 3842 6 feet is the chip output pin, if burned there, it is likely that the chip and switch are broken But the power output there is voltage, although unstable, indicating that the chip and switch is still working. You can test the chip 7 feet voltage is stable, if the stability of the power supply is likely to low side problems. If the voltage is unstable, when the high when the more difficult to repair this, it is likely to start from the chip.

Q: I do 12V2A switching power supply when the 2A load, under normal circumstances work is normal. But is the beginning of the load that moment, when adding more than 1.3A, the output voltage dropped first low and then quickly returned to normal, what reason? This is of course not normal, the same load, for someone else's power but not the problem. How should we solve this problem? Just test a phenomenon is that when the sudden removal of the load when the voltage is also the first drop and then return to normal state. How to solve it?: this is normal phenomenon. The load becomes larger, to maintain the same voltage, the power output impedance will become smaller, power duty cycle to become larger, the adjustment is the time required, the dynamic response speed of the voltage drop will be relatively small.
