Introduction to CC CV Power Supply
CC CV power supply, which stands for Constant - Current Constant - Voltage power supply, is a crucial type of power source in various industries. It can operate in two main modes: constant - current mode and constant - voltage mode. In constant - current mode, the power supply maintains a stable current output regardless of the load resistance changes within a certain range. This is particularly useful in applications such as battery charging, where a specific charging current needs to be maintained to ensure the safety and longevity of the battery. In constant - voltage mode, the power supply provides a fixed voltage output, which is essential for powering electronic devices that require a stable voltage to function properly, like integrated circuits and microcontrollers.
The demand for high - quality CC CV power supplies is increasing rapidly due to the growth of industries such as electronics manufacturing, renewable energy, and electric vehicle charging. As a result, many factories around the world are focusing on developing and producing advanced CC CV power supply products. Here are the top 10 CC CV power supply factories in the world in 2025:
