A Benchtop regulated Power Supply is a term for any power source that you can set up on a “bench” and is self contained in a case and a method of output connection. This can be Voltage, Current, Resistance or Power in many various configurations. A regulated power supply is a device meaning it converts unregulated AC into a constant DC voltage to supply power to a load.
What is the purpose of power supply units?
Power supply units are mainly used to test different power units in devices. They are efficient and steady so it allows the user to test or troubleshoot a device that runs off DC power. The voltage and current are adjustable so the power supply can be adapted to different devices.
In some cases a developer will need multiple power supply units to test a wider range than what one power supply can give. A great thing about power supply units is that they can be combined with other like power supplies to amplify the output for larger devices. Or there are multiple power supply units that can the cost it would be for three units and reduce but be just as suitable.
