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: , I personally think that electromagnetic excitation of this, in addition to resonance, the other amplitude is very small

Q: 24V switching power supply, 220V input and output three terminals: 24V + 24V- GND. Excuse me. Where is this GND connected? In the PLC (such as Siemens) on the L + M to (ground that symbol) Switching power supply is connected to the ground in the PLC? There are some sensors on the terminal marked with three vertical and horizontal grounding symbol, but also to be connected to the switching power supply on the symbol terminal? What is the relationship between the chassis and the switching power supply on this land? Is it a thing?: Yes, the reason why there are so many places, is to solve the EMC used

Q: What is the difference between Switch Mode Power Supply and electronic switch? Where are they?: Switching power supply is a large class, usually we say that the switching power supply is AC variable DC power supply, but in fact, including DC variable DC, DC variable AC (inverter) should belong to the switching power supply.

Q: Recently to be an automatic lift, switching power supply with the touch mode control and found that sometimes failure, into the frequency transformer is not the problem, the problem is only with the switching power supply, would like to ask if there is nothing to improve this Problem? Switching power supply is bought directly outside the back. There is not much change: Plus 4700 microfarads and 104.103.10p capacitors at the output and the input of your control circuit board In the touch of the power input side of the string into a 10 ohm or so resistance, put a 220 micro capacitor before the capacitor, put two 104.103, but also the resistance into inductance.

Q: In the design of switching power supply, the input power is smaller, switching transformer primary side of the inductance but the greater the? Transformer primary side of the greater the amount of inductance, the transformer is not the volume will increase?: DC "can have a different meaning, and if the voltage through the resistor does not produce a voltage drop through the resistor voltage drop is called" DC "voltage, then the DC refers to a constant voltage that does not change with time, or from the Fourier decomposition Is the DC component of the periodic signal (the DC component is equal to the mean in one cycle when the input is a periodic signal and the circuit has a periodic steady state). High frequency "DC voltage" is clearly not a constant voltage, it is estimated that the PWM thing, if it is a cycle input, then it will not only contain the DC component, but also contains the various sinusoidal AC component. Among them, the DC component in the inductor there is no pressure drop, and its components in the inductor voltage drop, so the coil inductance is certainly not short circuit. Of course, if the input signal DC component is too large, sinusoidal AC component is too small, then it may be too small inductance voltage, the entire coil current is too large. The above is the meaning of DC from the perspective of frequency domain analysis. Of course, if you avoid the concept of DC directly to the time domain analysis, that is, on the first floor zchy4610 analysis, high level charge, the current index rises, low level discharge, current index decreased, in any case, the peak current and average current are not The voltage is only added to the resistor so much.

Q: What are the LLVD and BLVD in the switching power supply?: Simply said that a power and the second power is the main circuit and the control circuit, respectively, in the mobile base station, the popular point that a power out of the equipment in addition to the transmission equipment are stopped to ensure that other Station to connect the station to transfer the station to work properly, the second power is to protect the battery and power failure, then all the equipment are stopped.

Q: What is the linearity of switching power supply: Different power supply, linear adjustment rate is different Constant pressure source: Linear adjustment rate: the rate of change of the output voltage within the specified input voltage range; ΔV / V = (V - V1) / V * 100% Load rate: change in load within the specified range, change rate of output voltage; ΔV / V = (V-V1) / V * 100% A constant current source: Linear adjustment rate: the rate of change of the output current within the specified input voltage range; ΔI / I = (I - I1) / I * 100% Load regulation: change in load within the specified range, change rate of output current; ΔI / I = (I-I1) / I * 100%

Q: Led lights switching power supply controller how to repair: If you just use it alone, it's broken. It is recommended to buy one. Because the maintenance needs to change the device, and their purchase of equipment is expensive, and can not determine that the device is bad. If you are learning to repair, it depends on the principle of switching power supply. Principles of understanding, the manufacturers work, maintenance is very simple.

Q: How to constant voltage switching power supply into a constant current, how to rectification ?: Can not be converted, because the work of different ways to work the object is also different. Due to constant voltage source and constant current source has different circuit characteristics, it can not be replaced with each other. The respective circuit characteristics are as follows: Constant voltage power supply (regulated power supply): can be a constant output voltage to the load power supply. The ideal internal resistance of the constant voltage power supply is zero and can not be shorted when used. Constant current power supply (constant current source): A power supply that can output a constant current to the load. The ideal internal resistance of the constant current power supply is infinite and can not be opened when used.

Q: For the specific parameters for the requirements (power: 350W or more working voltage: DC 300V) switch switch power supply which are commonly used? To say that there are specific places in Jinan where to sell? Anxious ~: Are you going to IGBT tube? Can be commonly used are transistors and MOS tube.
