Linearly adjustable DC constant current power supply is a kind of power supply equipment that can produce controllable constant current. This power supply works by adjusting the linear potentiometer so that the output current is constant. This power supply has a wide range of applications in many fields, such as scientific research, industrial production, and teaching experiments. DLC9000 series programmable linear DC power supply is a high-power high-precision DC power supply with AC single three-phase input and DC output, with a maximum power of up to 400kW.
1.The working principle of a linearly adjustable DC constant current power supply
The working principle of a linear adjustable DC constant current power supply is mainly achieved by adjusting the linear potentiometer. When the input voltage is fixed, the output current can be kept constant by adjusting the potentiometer. This is because a potentiometer is a variable resistor that can change the current in a circuit by adjusting the resistance of the potentiometer. When the resistance of the potentiometer increases, the current in the circuit decreases, and vice versa. Therefore, by adjusting the resistance of the potentiometer, the output current can be kept constant.
2.Application of Linearly Adjustable DC Constant Current Power Supply
