- Q: 24-volt switching power supply why leakage
- 3, the real induction power, as long as the power supply, whether it is power or switching power supply, the general transformer high voltage low side will have an equivalent capacitor, can be seen as the first two conditions, there will be a trace of leakage current, This situation can not be avoided.
- 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?
- Because this out of the voltage is more stable ah, do not you want your computer will be a bright one, and finally smoke ah!
- Q: What brand of switching power supply cost-effective?
- See what kind of switching power supply, LED, or industrial use, or communication.
- Q: What is the industrial switching power supply
- Industrial switching power supply refers to the switching power supply used in the industrial field Power can be divided into civil, industrial, military, and even aviation, aerospace Industrial switching power supply meets industrial requirements. For example, civil switching power supply generally require working temperature 0 ~ 70C, the industry is generally required in the -40 ~ 85C, military requirements are -55C can work properly.
- 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?
- Hello, now on the market power varies, the choice of power directly determines the product itself is good or bad, good power mainly to see the program, device platform, production technology, testing standards and a series.
- Q: Now I want to buy a larger power test power, about 1KW. I have no money, so I want to buy a switching power supply, so that you can save a lot of money, but do not know can not accept the emotional load
- If the switching power supply output DC, emotional / capacitive are not afraid. Direct current does not exist.
- 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,
- If you are measuring the ground wire, 1V thorn is not large, but you must take it out of the case, you can consider two ways 1, electrolytic capacitors and more can not solve the high-frequency noise, but with ceramic capacitors such as 10uF / 50V several and in the output port, the effect will be very good. 2, in the output plus a common mode, high frequency. You can reduce noise. The above two methods are feasible, you try it yourself
- Q: 12V10A switching power supply in the layout of the line when the longest cloth?
- 12V DC transmission loss is very large, with 2.5 lines up to 50 meters, bring the load voltage down to 10.5V /
- Q: Switching power supply maintenance methods can be divided into several steps
- 4, in the switching power supply repair practice, there are many switching power supply using UC38 × × series 8 feet PWM components, most of the power can not work because the power supply is damaged, or chip performance degradation. Starting current increases due to start circuit as shown below. When there is no VC after the open circuit, PWM components can not work, need to replace the same power resistance with the original resistance. When the PWM component starts to increase the current, you can reduce the R value to the PWM component can work properly. In the repair of a GE DR power supply, the PWM module for the UC3843, detection found no other anomalies, R (220K) and then a 220K resistor, PWM components work, the output voltage is normal. Sometimes due to the external circuit failure, resulting in the VR terminal 5V voltage is 0V, PWM components do not work, in the repair Kodak 8900 camera power supply, encountered this situation, connected with the VR side of the external circuit, VR from 0V to 5V, PWM components work properly, the output voltage is normal.
- Q: The hands of a switching power supply, the use of 2SC3320 switch, the output is 24V7A, after adding the load will always burn 2SC3320 switch, no load no problem, how is it, there are drawings, that expert help to see, thank you
- In general, the main reasons for the damage to the power switch tube are the following 13: ?????? 1. Soft start circuit failure ?????? 2. Switch tube integrated circuit board anti - peak absorption circuit failure ?????? 3. Positive feedback is too strong ?????? 4. Timing capacitor failure leakage ?????? 5. Decoupling Capacitor Failure in Regulating Circuit ?????? 6. The negative feedback loop of the regulator circuit
