Features
1. This DC regulated power supply is designed for scientific research, product development, laboratories, schools, production lines and electronic maintenance and other places of high-precision DC voltage regulated switching power supply. It features a uniquely designed LED display that visually displays output voltage and current. At the same time, it adopts continuously adjustable output voltage and current design, can automatically adjust the working mode within the set rated range, according to the load demand to achieve constant voltage or constant current, so as to effectively avoid possible damage to the load equipment.
2. This DC regulated power supply has the advantages of high efficiency, strong carrying capacity and low noise. The back is provided with a fuse holder, and the exposed part of the metal is connected with a ground wire to provide comprehensive protection for the safety of electricity.
3. This DC regulated power supply has the characteristics of high voltage stability, small ripple coefficient and perfect protection design. Including short-circuit protection, over-current protection and over-temperature protection and other functions to ensure that the equipment can operate safely and stably under various conditions.
4. This DC regulated power supply has the advantages of small volume, light weight and convenient transportation and carrying.
5. Users can easily switch between over current off and constant current protection modes by pressing a button, which is suitable for a wider range of loads. In the overcurrent shutdown mode, once the load current exceeds the preset value, the power supply will immediately cut off the output to ensure the load safety, and automatically resume normal work after troubleshooting. In the constant current protection mode, when the load current exceeds the preset value, the power supply will limit the current and reduce the voltage, and the load current will be controlled at the same level as the preset value, so as to effectively avoid all kinds of accidental interference and load damage.
6. This DC regulated power supply has USB fast charging function, support QC2.0, QC3.0 fast charging protocol, mobile phone charging faster.
7. DC regulated power supply can output DC voltage, not only can be used as a mobile phone, computer and other maintenance power supply, but also can be used to check and repair other electronic circuits or components.
8. The voltage of the DC regulated power supply is provided with two ranges of 0~5V/0~30V. When used for mobile phone inspection and maintenance, switching to 0-5V is more conducive to the safe use of mobile phones and improve the safety performance of products.

Constant voltage and Constant current (C.V/C.C) principle
The 3005D 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
