Some people may be using DC stabilized power supplies, but there are not many people who can really understand DC stabilized power supplies. Therefore, when the DC stabilized power supply fails, you are not sure how to solve the problem. You may know about DC stabilized power supplies. Is not very thorough, you may not know the following.
When understanding DC power supply, you need to consider the main structure of constant voltage, constant current and power supply.
First, you need to know that a regulated DC power supply has voltage but no current, and current has no voltage. At this point, the PSU has been working normally, so the PSU load is well connected. In extreme cases, the regulated DC power supply is in a constant voltage state, but the load is turned off and the output current is zero. When the regulated DC power supply is under constant current conditions, the load will be short-circuited and the output voltage will be zero.
In addition, do not turn off all current adjustment knobs. No-load voltage will not increase. I think many people don't know the reason. The power consumption is low when idle, because the current adjustment knob is completely closed, it will not rise, and because there is no current, it cannot be adjusted without a load.
The last point is that when the power supply is in a constant voltage state, the voltage at this time will be in the active position. In other words, the magnitude of the current is determined by the load, so adjusting the current will not change the current, but it will also change the current through the voltage adjustment knob.
In fact, DC stabilized power supply is not difficult to understand. We need to understand while reading the related knowledge of DC stabilized power supply, and be able to draw inferences about it. I believe that we will soon be able to understand the DC stabilized power supply thoroughly.
