Constant voltage and Constant current (C.V/C.C) principle
The 1503D DC power supply can be automatically converted in constant voltage or constant current operating mode. It transforms its state by comparing the value of the load current and the limit current.
Constant Voltage Mode (C.V) :
1. When the load current value is less than the set output current limit value, the power supply will work in constant voltage mode.
2. In this mode, the constant voltage indicator light on the panel will light up.
3. The output voltage will be controlled to be the same as the set value, and the current will change according to the load.
Constant Current Mode (C.C) :
1. When the load current value is greater than the set output current limit value, the power supply will work in constant current mode.
2. In this mode, the constant current indicator light on the panel will light up.
3. The output current will be controlled to the same value as the set output current limit.
4. Because the output power is limited and cannot be overloaded, the output voltage will be lower than the set value.
5. Once the output current is lower than the set output current limit value, the power supply will automatically switch to the constant voltage working state.
Application
1. Electronic product assembly
2. Product development in scientific research departments
3. Electronic products maintenance
4. Factory production line
5. Skill training in all kinds of electronic institutions
