DC power supplies are vital to any direct current powered device such as a welding device, computer components and battery charging. Any DC device can be driven with a DC power supply as long as the supply can match the voltage and current needed.

Some of the applications that this instrument is best suited for are a precision reasearch and development voltage and current source, repetitive production tests using setup recall feature, prototype board initial power-up with overload protection as well as in general purpose high power lab requirements.

With 1 adjustable output and 2 fixed outputs this instrument can power a wide range of devices. A single DC power supply with 3 outputs provides the ability to work with multiple DC powered devices at one time.
