- Q:Switching power supply CE certification is probably how much money
- Or how much money, there are two or three thousand cheap, you have seven or eight points, of course, the requirements of high, then there are more than ten thousand, specifically look at your needs, look at my name in detail
- Q:Computer host switch power supply how much money?
- Switching power supply are generally in the chassis above the only bad repair
- Q:Wireless communication room in the combination of switching power supply and integrated switching power supply and the difference between the respective functions?
- The central room of the DC power supply system is composed of AC power distribution screen, DC power distribution screen, switching power supply rack (including a control module and multiple rectifier module), two large-capacity battery and connect them between the power cable The The battery is a group of 24 components, each 2V. The total voltage is 48V.
Wireless communication room in the general use of wall-mounted AC distribution box instead of AC power distribution screen, the use of combined switching power supply to replace the DC distribution panel and switching power supply (including control module and rectifier module), so called the combination of switching power supply, DC power distribution panel and switching power supply rack together. Plus two sets of batteries. The battery is a group of 24 components, each 2V. The total voltage is 48V.
Integrated switching power supply is the AC power distribution and battery pack is also integrated into the rack, the equivalent of a rack to complete the central room of the DC power system all the features, but the capacity to be much smaller. Its battery pack is generally used 4, each 12V, the total voltage of 48V.
I found on the Internet under the MCS3000D-3 * 50A power supply, should be a combination of switching power supply.
- Q:Switching power supply and communication power difference
- and get more stable, more accurate, less interference Voltage, only to provide communication equipment.
- Q:Switching power supply maintenance methods can be divided into several steps
- 5, when the filter capacitor no 380VDC voltage, indicating that the PFC circuit is not working properly, PFC module key detection pin for the power input pin VC, start the foot Vstart / control, CT and RT feet and V0 feet. When repairing a Fuji 3000 camera, test an on-board filter capacitor without 380VDC voltage. VC, Vstart / control, CT and RT waveforms and V0 waveforms are normal, measuring field effect power switch G very no V0 waveform, because FA5331 (PFC) for the patch components, the machine appears after a long time between the V0 and the board between the virtual Welding, V0 signal is not sent to the field effect transistor G pole. The V0 end with the board solder joint welding, with a multimeter to measure the filter capacitor has 380VDC voltage. When the Vstart / control side is low, PFC can not work, you have to check the end of the connection with the external circuit.
In short, the switching power supply circuit is easy and difficult, the power is very small, the output voltage varied. As long as the core of things to grasp, that is fully familiar with the basic structure of the switching power supply and the characteristics of PFC and PWM modules, the basic conditions of their work, in accordance with the above steps and methods, multi-hands maintenance of switching power supply, you can quickly remove the switch Power failure, to achieve a multiplier effect.
- Q:Switching power supply start-up time, hold time, long time, fall time, which standard
- Switching power supply start time is the power switch to close to the output voltage of 90% of the Uo up to that time;
Hold time is the power switch off, to the output voltage dropped to 90% of the Uo period of time;
Rise time is the power supply output voltage from 10% Uo up to 90% of the Uo period of time;
The falling time is the time that the output voltage of the power supply drops from 90% of Uo to 10% of Uo.
- Q:Switching power supply (AC-DC) use notes and tips
- Power Usage Precautions:
First, the metal shell Power cord and the shell is generally connected with the ground (FG), to be reliable grounding, to ensure safety, can not be mistaken to the shell connected to the zero line.
Second, before the installation is complete power test run, please re-check and proofread the wiring on the wiring, make sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current value is correct Before they can run.
Third, for high-power LED switching power supply, there are three or more than three "+" input terminals and "-" output terminals, in fact they belong to an output electrode, just to make the user easy to connect, and multiple terminals Respectively, in the internal and then together.
- Q:Car cd with the battery all right, with a switching power supply speaker has a buzzing sound
- Voltage big bar, it should be between 12 volts to 15 volts,
- Q:Switching power supply, starting resistance is very hot, no output
- That is, switching power supply can not afford to vibrate, if it is self-oscillation to check the rectifier components are not short-circuit, positive feedback circuit is not normal.
- Q:What is the basic principle of switching power supply?
- The exchange through the diode rectifier. Capacitor filter into DC, and then through the 1620KHz high frequency oscillation generator. Switch and high frequency switching transformer role, the DC into the required amplitude of the high frequency pulse voltage. And finally through the high frequency of the two poles to the high frequency pulse voltage rectification. Capacitance filter output required DC voltage. The output regulator is to rely on the output to remove the sampling voltage to adjust the oscillator frequency and pulse duty cycle.
