Q: The main function of the communication switching power supply is: Ask some general. The Upstairs answered yes. The You want to buy the goods to find me

Q: What is the meaning of hiccups in switching power supplies?: Hiccups that the switching power supply in the output short circuit and other failures, the switching power supply chip after working hundreds of milliseconds and then stop working for a few seconds, and then start working hundreds of milliseconds, continuous cycle.

Q: Power amplifier with a good power or good switching power supply?: Generally believed that the best R-type transformer, ring type, switching power supply transient response is not enough, open-loop can be used, but the effect is poor. Now there are dedicated power amplifier switching power supply, the main features are: resonant switch circuit; (and the same effect as the transformer sine wave effect, very little interference, the car amplifier has been using resonant circuit). Open-loop output, not regulated output, no response time. Heavy weight, high efficiency and so behind are nonsense

Q: How to make the switching power supply does not delay power: Use a relay to control the output of the switching power supply.

Q: Switching power supply how to connect to the battery charge: The output of the switching power supply is connected to the positive pole of the battery, the output negative of the switching power supply is connected with the negative pole of the battery, and then the switching power input terminal can be inserted into the socket. If you do not know the battery and switching power supply positive and negative, you can use a multimeter to connect the switching power supply output port test, the display voltage is positive, then the red pen is connected to the positive, black pen is connected to the negative.

Q: I am in Guangzhou, need to purchase switching power supply, would like to know how we look for channels to buy? A lot of come to recommend the manufacturers, there are many outside the electronic market, there are a lot of online, I do not know how to distinguish between good and bad ah .... how to cost higher?: Shenzhen Luyuan Rui Di Electronic Technology Co., Ltd. is a professional design, development, production and sales of switching power supply professional company, the product has a low price, high reliability, high efficiency, low operating temperature Small size, light weight, etc., widely used in industrial control preparation, LED display, instrumentation and other industries, is the traditional control transformer ideal replacement products. Companies with a strong technical force, advanced production technology, improve the detection equipment, well-trained management personnel and scientific and technological personnel, the courage to innovate, forge ahead, the use of advanced technology, the implementation of scientific management. Technology production cast a good Luyuan Rui Di quality, the product through the national center of the rigorous testing. Stable performance, safe and reliable operation, the majority of users by the trust and respected, the best-selling products in major provinces and cities and overseas markets.

Q: What are the LLVD and BLVD in the switching power supply?: Distribution of the AC power into the switching power supply, after rectification, transformer output -48 volts, while the battery pack float, are charged operation. When the mains input interrupt, the battery pack began to discharge, to access the switching power supply load such as base station equipment (BTS), transmission equipment (Guangduan Ji), to ensure the normal operation of the base station. When the battery voltage drops to the switching power supply set a voltage, the switching power supply off the power terminal connected to a non-critical business load; battery continues to discharge, to the second power supply terminal above the important business load , When the battery voltage drops to the second voltage, the switching power supply to cut off all the load to protect the battery pack will not appear over discharge phenomenon, over discharge on the battery is fatal, and is irreversible, will cause the whole group of batteries scrapped , But tens of thousands of dollars it ????Generally the base station equipment (BTS) access to a power, the transmission equipment (Optical) and other access to the second power. Once, the second power supply voltage settings are in the switching power supply, the specific parameters according to the battery capacity, battery life, load power and other parameters set.

Q: What is the meaning of the magnetic ring color in the switching power supply?: Switching power supply used in the magnetic ring generally there are two, one is the high permeability of the green ring, used in the input and output. The color is green. Do common mode inductance use. One is power type. If it is black or blue, is generally iron silicon aluminum. If it is blue-green material is -52 core powder. If it is yellow and white is -26 material iron core, do energy storage inductors use. There are some more special applications are transformers. Drive transformer magnetic ring. Magnetic beads, dc head filter magnetic ring. Division I is a professional transformer. There is not clear you can talk to me.

Q: The meaning of the lines of the computer switching power supply: Red: on behalf of +5 V power line (motherboard, hard drive, optical drive and other hardware on the chip operating voltage). Yellow: on behalf of +12 V power cord (hard drive, optical drive, fan and other hardware on the operating voltage, and -12V at the same time to the serial port to provide EIA power). Orange: represents + 3.3V power cable (directly to DIMM, AGP slot). Gray: on behalf of the PG signal line (power status information line, it is the other power lines through a certain circuit to calculate the results, when the press the computer after the first key, the signal that the power can be turned on without signal that there is faulty motherboard automatic monitoring) T

Q: 12V switching power supply measurement 13.7V normal?: Adjust it to 12V, the terminal next to the adjustment potentiometer
