What are the types of DC regulated power supplies
With the continuous development of DC stabilized power supply, it has been widely used for DC power supply in national defense, scientific research, universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, charging equipment, etc. But with the increasing use of DC stabilized power supplies, their types are also becoming more diverse. So what are the classifications of DC stabilized power supplies?
1. Multi channel adjustable DC stabilized power supply
Multi channel adjustable DC stabilized power supply is a type of adjustable stabilized power supply, characterized by one power supply providing two or even three or four independently adjustable voltage outputs.
Basically, it can be seen as the combination of several single output power sources, suitable for situations that require multiple voltage supplies. A more advanced multi-channel power supply also has voltage tracking function, allowing several outputs to be coordinated and regulated.
2. Precision adjustable DC stabilized power supply
Precision adjustable DC stabilized power supply is a type of adjustable stabilized power supply, characterized by high voltage and current regulation resolution, and voltage setting accuracy better than 0.01V. In order to accurately display voltage, the mainstream precision power supplies currently use multi bit digital meters for indication.
The solutions for voltage and current limiting precision adjustment mechanisms are different. The low-cost solution uses two potentiometers for coarse and fine adjustment, while the standard solution uses a multi turn potentiometer. The high-end power supply uses digital settings controlled by a microcontroller.
3. High resolution CNC power supply
The stabilized power supply controlled by a microcontroller is also known as a numerical control power supply, which is easier to achieve precise adjustment and setting through numerical control. The internal circuit of precision stabilized power supply is also relatively advanced, with good voltage stability and small voltage drift, and is usually suitable for precision experimental occasions.
Precision DC stabilized power supply is a term used in China. Imported power supplies from abroad generally do not have a nominal precision power supply, only high-resolution power supplies and programmable power supplies.
4. Programmable power supply
Programmable power supply is an adjustable regulated power supply controlled by a single chip microcomputer in a digital form. Its set parameters can be stored for future use. There are many parameters for programmable power supply settings, including basic voltage settings, power limit settings, overcurrent settings, and extended overvoltage settings.
Programmable power supplies typically have high setting resolution, and voltage and current parameters can be set through a numeric keypad. High end programmable power supplies have minimal voltage drift and are commonly used in scientific research settings.
