An adjustable DC power supply is a manual type of variable supply that lets you fine-tune voltage and current using dials or digital input. These are ideal for precise testing, lab use, and electronics maintenance. The term variable DC power supply refers to a broader category. It can include adjustable units, but also programmable ones that automatically shift voltage based on load or preset conditions. Here, we focus on adjustable units that give you full manual control—perfect for technicians, DIYers, and students.
