Constant Voltage Constant Current (CV/CC) Principles
YIHUA-602D DC power supply can automatically convert under the condition of constant voltage constant current work mode. Its status is determined through the comparison between the values of loading current and limited current.

1. Constant Voltage Mode (CV)
The power device works in the constant voltage mode, when the current value is smaller than the set output limited current. The front panel constant voltage indicator will light up. Meanwhile, the output voltage will be controlled to be the same as the set value. The current will change according to the load.

2. Constant Current Mode (CC)
When the current value exceeds the limit value of the output current, the power unit will work in the mode of constant current. Besides that, the constant current indicator of front panel will light up, and the output current value will be controlled within the set value. Since the limited output power can not overload, the output voltage will be lower than the set value. Once the output current is lower than the set value, the YIHUA-602D DC power supply will automatically convert to the constant current work mode.

Constant Voltage Constant Current (CV/CC) Principles
Under the condition of constant voltage constant current work mode, YIHUA-603D DC power supply can automatically convert. Through comparing the values of loading current and limited current, you can determine its status.

1. Constant Voltage Mode (CV)
When the current value is smaller than the set output limited current, the power unit works in the constant voltage mode, and the front panel constant voltage indicator will light up. In addition, the output voltage will be controlled to be the same as the set value. The current will change in accordance with the load.

2. Constant Current Mode (CC)
The power unit will work in the mode of constant current, when the current value exceeds the limit value of the output current. Not only will the front panel constant current indicator will be on, but also the output current value will be controlled to be below the set value. Because the limited output power can not overload, the output voltage will be kept lower than the set value. When the output current is lower than the set value, the power device will automatically convert to the constant current work mode.

Constant Voltage Constant Current (CV/CC) Principles
YIHUA-605D DC power supply can automatically convert when working in the mode of constant voltage constant current. Its status can be determined by the comparison of loading current value and limited current value.

1. Constant Voltage Mode (CV)
When the set output limited current is larger than the current value, the power unit will work in the constant voltage mode. Then, the front panel constant voltage indicator will light up, and the output voltage will be controlled to be the same as the set value. The current will change as the load changes.

2. Constant Current Mode (CC)
This YIHUA-605D DC power supply will work in the mode of constant current, if the current value is larger than the limit value of the output current. Moreover, the front panel constant current indicator will be on, and the output current value will be controlled to be below the set value.

The limited output power can not overload. For that reason, the output voltage will be kept lower than the set value. Once the output current is below the set value, the power device will automatically convert to the constant current work mode.
