Question:

Can DC Regulated Power Supply Output Negative Voltage?

There are positive, GND and negative, GND and negative connected together.

Answer:

If your power supply is the two output terminals, the negative side as a reference, you can think it is a positive power supply, with positive for reference, it can be considered a negative power supply.
You are the three power nodes, there are positive and negative power supply and reference side GND, I do not know what you want negative voltage. But you said, "GND and the negative together," is absolutely not, so burned.
1, the power supply is the two output terminals to negative as a reference, you can think it is a positive power supply, with positive as a reference, it can be considered a negative power supply. 2, DC power supply refers to the ambient temperature, load size, input voltage and other factors will make the DC voltage regulator output voltage changes in the power supply. 3, the power supply of the classification of many methods, according to the type of output power supply DC power supply and AC power supply; according to the regulator circuit and the load connection is divided into series power supply and parallel power supply; The working status of the tube is divided into linear power supply and switching power supply. According to the circuit type, there are simple power supply and feedback type power supply. So many of the classification is often so that beginners puzzled, do not know where to start. In fact, it should be said that these seemingly a lot of classification between the methods have a certain level of relationship, as long as the level of this level can naturally distinguish the type of power.
