- Q: I encountered a similar problem with you, I use the 12V switching power supply with dimming decoder, into the dimming console DMX512 control, in the dimming when the switching power supply is creak sound, ask you there A better solution? thank
- the human ear should not reach this sensitive range.
- 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?
- You can use the hot blow to blow inside, if it is temperature control of the fan, blowing for a while will turn, if still do not turn, it should be the fan is broken
- Q: We use the switching power supply is 220v-48v, the room has air conditioning, air conditioning power in 6kw or so, the total power of this room in 17kw, DC current is 60A, the room has two tubes. Now do not know how much switching power supply losses, these devices may have 17kw power? This is the 17kw power meter on the show. Who heroes help me.
- Need to know the switching power supply load current or load power and switching power supply efficiency. General switching power supply efficiency (220v-48v) is greater than 80%, 80% efficiency, its power consumption is equal to the load / 80%. Glossary: Switching power supply is the use of modern power electronics technology to control the switch on and off the time ratio, to maintain a stable output voltage of a power supply, switching power supply generally by the pulse width modulation (PWM) control IC and MOSFET composition. With the power electronics technology development and innovation, making switching power supply technology is constantly innovating. At present, the switching power supply to small, lightweight and efficient features are widely used almost all of the electronic equipment, electronic information industry is the rapid development of an indispensable power supply. With the rapid development of power electronics technology, power electronic equipment and people's work and life increasingly close relationship, and electronic equipment are inseparable from the reliable power supply, into the 80's computer power to fully realize the switching power supply, the first to complete the computer Power supply, into the 90's switching power supply have entered a variety of electronic, electrical equipment, program-controlled switches, communications, electronic testing equipment, power supply, control equipment, power supplies have been widely used switching power supply, but also promote the rapid development of switching power supply technology
- Q: How to make the switching power supply does not delay power
- If you want to add their own words at the same time chanting Do not need to isolate the direct use of the input to control a switch when the input voltage is not the time to turn on the switch tube power output pull If you need isolation with optocoupler to control the switch tube
- Q: Name and function of the components of the switching power supply T1, T2, R11, R12, D6, C2, Q1, D5, U1, U6,
- commonly used as PC817. Since the switching power supply between the primary and secondary need to be isolated, there is no circuit between them can be directly connected, so the secondary voltage signal with it into an optical signal, and then in its internal and then become an electrical signal to complete the feedback Regulator process, while achieving isolation.
- Q: Ups and high frequency switching power supply
- UPS and high-frequency switching power supply The main difference: High-frequency switching power supply, refers to the use of power switching devices, at high frequencies through the converter for energy conversion power. High-frequency switching power supply (also known as switching rectifier SMR) through the MOSFET or IGBT high-frequency operation, the switching frequency is generally controlled in the 50-100kHz range, to achieve high efficiency and miniaturization. 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: What is the core of switching power supply design?
- Power density ratio; soft start; DC-DC conversion, rectification, EMI, intelligent control.
- 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: Yesterday when the transformer to find a problem, a boost inductance, my air gap plus the greater the inductance of the smaller, but a counterattack transformer my air gap plus the more inductance but the greater, now a bit can not figure out.
- You are not a flyback transformer only done once the air gap concluded that there may be two of your core wrapped around the loose is not the same, anyway, it is impossible under the same conditions, the air gap to increase the amount of inductance but large.
- Q: Ming Wei switching power supply is why use?Ming Wei switch what to use, I see he is a circuit board, five wiring of the mouth, he used in the equipment what is the use? What is his general effect on the equipment?
- Regardless of the brand of switching power supply, the function is the same, to the equipment power supply, the general electrical equipment no matter what the external input is 110v or 2200v AC, the internal power are DC, usually with positive and negative 24v, 15v 5v And so on, switching power supply, is the exchange of alternating current into a stable DC for the use of equipment
