Constant Voltage Constant Current (CV / CC) Principles
In the mode of constant voltage constant current, YIHUA-3010D DC power supply can be automatically converted. Its status is determined by the result of the comparison between the load current and the limited current value.
1. Constant Voltage Mode (CV)
When the current value is smaller than the set output limited current value, the power supply unit will work in constant voltage mode. Under such condition, the front panel constant voltage indicator lights up. The output voltage will be controlled to be the same as the set value. Meanwhile, the current will change as the load changes.
2. Constant Current Mode (CC)
The device will work in constant current mode when the current value exceeds the limit value of the output current. Additionally, the front panel constant current indicator lights up, and the output current value will be controlled within the set value. For avoiding the overloading of the limited output power, the output voltage will be lower than the set value. Once the output current is lower than the set value, the YIHUA-3010D DC power supply will automatically be converted to constant current work status.
