Mount these power supplies into standard 19”-wide electronics racks, which can hold multiple electronic devices and keep your benchtop clear. These power supplies change AC voltage to DC voltage to power highly sensitive audio, measuring, and testing devices while keeping electronic interference—known as output or ripple noise—from passing on to the device. The lower the output noise value, the less interference the power supplies will create.

Designed with linear voltage regulation, these power supplies produce the same voltage regardless of changes in the input voltage or the amount of current being drawn. They are also known as linear power supplies. As they send power to a device, they use remote voltage sensing to check for any drops in the voltage. If the voltage dips, they can compensate with extra power, so connected devices always receive the correct voltage.

If you exceed the maximum current or load, these power supplies will shut down to protect both the power supply and the connected device.

View the output on a digital or analog display. Digital displays are often easier to read than analog displays, so you can quickly see if you need to make adjustments. Analog displays are better than digital displays for monitoring fast output changes, such as dips and spikes.
