Control your XEL benchtop supply via a LAN

Written on January 9, 2018 at 12:51 pm, by

For most benchtop power supply applications, the most important feature is a user interface that allows an engineer or technician to set up the power supply quickly and easily using the front panel. Benchtop power supplies, like the Sorensen XEL Series, have this kind of interface. For example, the XEL Series has a fine control […]

Total cost of ownership is more than just price

Written on January 4, 2018 at 7:01 am, by

When you purchase a power supply, you need to take into account more than just the price of the supply. The price is just one of the factors in the total cost of ownership. Other factors include: sales and application support, ease of use, downtime for calibration, repair, and upgrades Sales and application support is […]

Get the most out of your rack-mount power supplies

Written on January 2, 2018 at 7:07 am, by

While electronics technologies have come and gone, mounting them in 19-in. racks is as popular as ever. There are various theories over the origin of the 19-in. rack, but Practical-Home-Theater-Guide.com says that George Westinghouse used 19-in racks in 1890s to mount railroad relays. Then, in the early 1900s, telephone companies designed their switches to fit […]

Benchtop power supply features ensure DUT safety

Written on September 26, 2017 at 9:03 am, by

Everyone’s under pressure these days to get results. So, there’s nothing worse than getting your bench test all set up, throwing the switch, and watching some of the magic smoke escape because of some setup error. To prevent this from happening when you’re under pressure, you need the Sorensen XBT 32-3FTP True Triple Output Digital […]

Know Your Power Supply Jargon: Regulation

Written on September 3, 2017 at 6:23 am, by

The most important thing that a power supply does is to maintain a constant voltage output or a constant current output. This is true whether the power supply is built into a product and provides fixed output voltages, such as a desktop computer power supply, or a power supply that is on the test bench […]

Sorensen SG Series ensures auto parts reliability

Written on August 28, 2017 at 7:31 am, by

One of the big challenges when designing and manufacturing auto parts is ensuring that they operate reliably in very hot environments, such as Dubai, where the high temperature can easily reach 40˚C. Of course, they must also operate reliably in very cold environments, such as Siberia, where the thermometer can drop to -40˚C or below. […]

Minimize noise from power supplies when making low-level measurements

Written on August 1, 2017 at 7:22 am, by

Low-level measurements are susceptible to noise from a number of different sources. While discussing all the ways that noise can degrade low-level measurements is outside the scope of this article, let’s at least consider how to make sure that your test system power supply is not a problem: Start with a low-noise power supply. The […]

Know Your Power Supply Jargon: Ripple

Written on July 14, 2017 at 8:06 am, by

AMETEK Programmable Power DC power supplies convert AC power to DC power. While our supplies are very good at doing this, they’re not perfect. On the output, there will be some small amount of AC still present. This is called ripple. Minimizing ripple is important because excessive ripple because it can have adverse effects on […]
