- Q: I have a 12V3A switching power supply. From 0V to 12V, 2V3V can start. Want to carry out voltage regulation. How to do? If you use the potentiometer to connect the kind of potentiometer. I connected to the permanent magnet three brush motor is the car with the wiper motor, the motor high and low speed adjustment. Originally wiper motor there are two blocks. Richer speed adjustment.
- With a potentiometer to the 12V3 amp DC motor speed, the voltage drop in the potentiometer (variable resistor) on the energy consumption of large (and fever), you that 12V3A switching power supply from 0V, 2V, 3V - -12V continuous adjustment
- Q: Note the operating conditions of 220V voltage and the order of switching power supply
- Power failure - electricity - lock - seal ground - warning signs
- Q: Switching power supply and communication power difference
- and get more stable, more accurate, less interference Voltage, only to provide communication equipment.
- 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?
- Just for the boot convenient, do not switch how you boot? Shut down the general use of the system off. Power on the shutdown is a longer process. A part of a part of the start off. More details later say
- Q: What is the difference between a switching power supply and a switching regulator?
- 2, switching regulator, the key word is in the regulator, so the output of the switching power supply has a negative feedback sampling circuit, can play the role of regulation, usually switching power supply efficiency will be relatively high, the input dynamic range comparison Large, dynamic response is better, so now more widely used.
- Q: AC-DC switching power supply, how to connect, input AC, AC, FG three ends
- If not marked L fire line, N zero line; AC AC can be connected to the fire line and the zero line;
- Q: Switching power supply life is generally how long?
- Now the earliest imported color TV has been more than 20 years, individual families have used to prove that switching power at least in more than 20 years. Of course, quality is not qualified in this column.
- Q: Four-way monitoring switching power supply is not just a camera circuit can all the way? Or is there a problem with the equipment or line? The camera will appear short-term flash, shaking, black screen phenomenon. Now is the four cameras are connected to the positive and negative, the power is 12V6.3A, plus a small 12V1A power alone access to a camera, the results of a separate shine, the last black screen. The original problem of the camera or a problem, no problem or no problem. And the fault is short, I suspect that the camera problem, but the manufacturers that no problem. Depressed ah! Which a master to help one.
- Power supply is insufficient, four of the best choice of five or more switching power supply!
- Q: Isolation switch power supply and non-isolated switching power supply advantages and disadvantages,
- Isolation type: Advantages: before and after the isolation, after the level of the earth without dangerous voltage, the output voltage can be equal to the input voltage or can contain a range of input voltage Disadvantages: larger, or the same size of the power smaller Scope of application: the occasion of electricity supply (such as computer power); signal detection to isolate the collection of occasions (such as electrocardiograph)
- Q: What is offline LED driver? Offline switching power supply
- Off-line switching power supply, also known as isolated switching power supply, is an AC-DC converter circuit. AC and DC are isolated by transformer. In some laboratories or high demand occasions, for the safety of the experimental staff, the experimental input power is generally used 1: 1 frequency transformer and the mains to isolate, so that the laboratory laboratory personnel regardless of which line encountered The root line will not have the risk of electric shock, because the isolated power and the earth is not connected. In industrial control equipment, it is sometimes necessary to isolate the power supply lines between the two systems, such as isolating ground noise, isolating high common mode voltages, etc., using a DC converter with a transformer to separate the two power supplies They are independent of each other, in order to achieve the above purpose. Each module is powered separately to prevent a module from damaging other modules due to high voltage discharge or other causes. The purpose of this can be to ensure that each module is working independently and undisturbed.
