The Meaning and Usage of CV and CC Modes in DC Stabilized Power Supply
In the field of electronic testing and development, DC stabilized power supplies play a crucial role. Their CV (constant voltage) and CC (constant current) modes provide stable and reliable power support for circuit design, battery testing, electrochemical applications, and more. This article will offer a detailed analysis of the meanings and usages of these two modes, incorporating relevant information about KUAIQU brand power supply products.
I. CV (Constant Voltage) Mode: The Cornerstone of Stable Voltage
Working Principle
In CV mode, a DC stabilized power supply can automatically adjust the output current to ensure that the output voltage remains constant. Regardless of changes in load resistance, the power supply can precisely maintain the preset voltage value, providing a stable power environment for voltage-sensitive devices.
Application Example from KUAIQU Brand
The DC stabilized power supplies of the KUAIQU brand, such as: KUAIQU SPPS-C1203 120V 3A one of its popular models, demonstrate remarkable stability in CV mode. This product can provide continuous and stable voltage output for voltage-sensitive components like digital circuits and microcontrollers, ensuring the accuracy of test conditions and improving the reliability of test results. In electrochemical applications such as electroplating, the CV mode of this product also guarantees the uniformity and consistency of the electroplating process, enhancing product quality.
Application Scenarios
· Electronic Circuit Testing: Offers stable voltage for voltage-sensitive components to ensure test accuracy.
· Late-stage Battery Charging: Maintains the battery voltage within a safe range to prevent overcharging.
· Electrochemical Applications: Such as electroplating processes, ensuring the uniformity and consistency of the electroplating process.
II. CC (Constant Current) Mode: A Precision Tool for Current Control
Working Principle
In CC mode, a DC stabilized power supply maintains a constant output current by adjusting the output voltage. Faced with changes in load resistance, the power supply can respond quickly to ensure that the current remains stable at the present value, preventing damage to devices due to excessive current.
Application Example from KUAIQU Brand
KUAIQU SPPS-C3010 30V 10A, another low voltage DC stabilized power supply product from KUAIQU excels in CC mode. This product is particularly suitable for the initial stage of battery charging, providing fast and controllable charging current to ensure safe and efficient charging of the battery. Meanwhile, in current limiting tests, the CC mode of this product can also simulate specific current conditions to verify the performance of circuits under extreme conditions.
Application Scenarios
· Initial-stage Battery Charging: Provides fast and controllable charging current to protect the battery from damage.
· Current Limiting Tests: Simulates specific current conditions to verify circuit performance.
· Electrochemical Analysis: Such as electrolysis processes, ensuring the stability of reaction rates and the consistency of products.
III. Intelligent Switching Function of KUAIQU Brand Power Supply Products
Modern DC stabilized power supplies, including multiple models from the KUAIQU brand, feature intelligent switching functions. They can automatically switch between CV and CC modes based on load requirements and user presets. When the load current demand exceeds the user-set limit, the power supply automatically switches to CC mode to protect the equipment and load; otherwise, it remains in CV mode to provide stable voltage output. This intelligent switching mechanism greatly enhances the adaptability and safety of the power supply.
IV. Diverse Selection of KUAIQU Brand DC Stabilized Power Supplies
The KUAIQU brand offers a wide range of DC stabilized power supplies to meet the needs of different users:
· High-voltage Models: Suitable for special application scenarios requiring high-voltage output, such as high-voltage electronic equipment testing.
