1.Mobile Phone / Laptop Projects
This is a great unit to have if you're working with mobile phones & small electronic projects with different voltage and current requirements for safe operations. You can adjust different parameters to suit the specifications of different devices without having to purchase a dedicated adaptor for each of them
2.Small / General Electronic Project
With reliable failsafe functions and great output precision, this unit is also widely endorsed in the laptop repair businesses. How it works:In a potential overload, the built-in overload protection function kicks in to cut the power and protect the board and components from frying.
3.Constant Current (C.C. Mode)
In C.C. mode, the power supply will ONLY allow change in the voltage value while keeping the current value constant. How it works:When you're powering current-sensitive components such as a fuse / semi-conductor / LED, the power supply can regulate the current output to your set value.
4.Constant Voltage (C.V. Mode)
In C.V. mode, the power supply will ONLY change the current value while keeping the voltage value constant. How it works:When you're powering components or devices with higher voltage requirements, such as an electric motor or a circuit, the C.V. mode keeps the voltage value constant (regulated) while keeping the current value available for changes to power the load
