What is the classification of DC stabilized power supply
With the continuous development of DC regulated power supply, DC regulated power supply has been widely used in national defense, scientific research, colleges and universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, charging equipment and other DC power supply. But with the increase in the use of DC regulated power supply, it is also more and more types. So what are the classifications of DC regulated power supply?
1、Multi-adjustable DC regulated power supply
Multi-adjustable DC regulated power supply is a kind of adjustable regulated power supply, which is characterized by a power supply to provide two or even three or four ways can be set independently of the voltage output.
Basically, it can be regarded as several single output power supplies used in combination, which is suitable for occasions requiring multiple voltage supply. Advanced multi-channel power supply also has a voltage tracking function, so that several outputs can be linked to adjust.
2, precision adjustable dc regulated power supply
Precision adjustable DC regulated power supply is a kind of adjustable regulated power supply, which is characterized by high resolution of voltage and current regulation, the voltage setting accuracy is better than 0.01 V. In order to accurately display the voltage, the mainstream precision power supply are used in the multi-bit digital table instructions.
Voltage and current-limiting precision regulation mechanism of different solutions, low-cost solutions using coarse and fine adjustment of the two potentiometers, the standard solution is to use a multi-turn potentiometer, high-grade power supply is used in microcontroller-controlled digital settings.
3、High resolution numerical control power supply
The use of microcontroller-controlled voltage regulator power supply is also known as CNC power supply, through the CNC method is easier to realize the precision adjustment and setting. Precision regulated power supply internal circuit is also more advanced, voltage stability is also better than its own voltage drift is small, usually applied to precision experimental occasions.
Precision DC regulated power supply is the name of the domestic foreign imports of power supply is basically not labeled precision power supply, only high-resolution power supply and programmable power supply.
4, programmable power supply
Programmable power supply is a microcontroller in the form of digital control of adjustable voltage regulator, its set parameters can be stored for future calls. Programmable power supply set more parameters, including the basic voltage settings, power limit settings, overcurrent settings and extended overvoltage settings and other information.
Usually programmable power supplies have a high setting resolution, voltage and current parameters can be set through the digital keyboard input. Mid-range and high-grade programmable power supplies also have a very small voltage drift of their own, and are mostly used in scientific research applications.
