What types of DC regulated power supply include
Due to the continuous development of DC regulated power supplies, the current DC regulated power supplies are widely used as DC power supplies for national defense, scientific research, universities, laboratories, industrial and mining enterprises, electrolysis, electroplating and charging equipment. However, as the range of use of regulated DC power supplies increases, its types will also increase. So, what types of regulated DC power supplies are there?
1. Multi-channel adjustable DC power supply
Multi-channel adjustable DC power supply is an adjustable tuning power supply, which is characterized in that a single power supply can independently set the voltage for two, three or four outputs.
Basically, it can be considered as a combination of multiple single-output power supplies, suitable for situations where multiple voltage power supplies are required. More advanced multi-channel power supplies also feature voltage tracking, allowing you to combine and adjust multiple outputs.
2. Precisely adjustable DC power supply
A precision adjustable DC power supply is an adjustable power supply with high voltage/current adjustment resolution and voltage setting accuracy of 0.01V or higher. In order to accurately display the voltage, the current mainstream precision power supplies use multi-digit digital meters to display.
The precise adjustment mechanism solutions for voltage and current limiting are different. The low-cost solution uses two potentiometers for coarse and fine adjustment, the standard solution uses a multi-turn potentiometer, and the high-side power supply uses a digital setting controlled by a microcontroller.
3. High-resolution CNC power supply
A regulated power supply controlled by a single-chip micrometer is also known as a numerically controlled power supply, and digital control facilitates precise adjustments and settings. The internal circuit of the regulated power supply is also relatively advanced, with good voltage stability and small voltage drift, which is usually suitable for precision experiments.
Precision DC regulated power supply is a domestic name. The power supplies imported from overseas basically have no nominal precision power supplies, only high-resolution power supplies and programmable power supplies.
4. Programmable power supply
Programmable power supply is an adjustable power supply, which is digitally controlled by a single-chip microcomputer, and its setting parameters can be saved for later use. Programmable power settings have many parameters such as basic voltage settings, power limit settings, overcurrent settings, and extended overvoltage settings.
