Features
1. This DC regulated power supply is a high-precision single-output DC power supply with continuously adjustable output voltage and current. It can automatically adjust the working mode within the set rating range, and achieve constant voltage or constant current according to the load demand, effectively avoiding the damage that may be caused to the load equipment. In addition, you can choose two different range current output options by pressing the button to switch between 0~5A and 0~999mA. As an important tool in the communication industry, the power supply is widely used in the production line, maintenance and commissioning of telecommunications products, and is also widely used in laboratories and other places.
2. The back of the DC regulated power supply 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. DC regulated power supply also has the functions of limiting current, reducing voltage, short-circuit protection, over-temperature protection, etc., so as to avoid all kinds of unexpected interference and burning load phenomenon.
4. 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.

Constant voltage and Constant current (C.V/C.C) principle
The 305D 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
