Test costs can add considerably to overall manufacturing costs, especially when extensive testing is required. That’s why it’s important to keep test costs to a minimum. Reduced test costs translate to lower manufacturing costs. Modern power supplies, such as California Instruments’ Asterion Series, have several features that can help you reduce test costs: Faster command […]

Using an Adjustable Power Supply with Tracking Outputs

Written on May 15, 2017 at 9:50 am, by

Many op-amp circuits used in analog applications, such as signal conditioning for high bit count analog-to-digital converters require the use of both positive and negative power supply voltages, as shown in Figure 1. Supplying both positive and negative voltages allows input signals and output signals to swing both positive and negative. You could power these […]

Electronic Load Selection: Volts, Amps, and Model Numbers

Written on May 15, 2017 at 9:43 am, by

Often the selection of programmable power supplies is based upon how high a voltage it can produce or how much current it can source. When selecting an electronic load, however, you need to consider not only volts and amps, but power as well. For example, the SLH-500-6-1800 has a maximum input voltage of 500 VDC […]

Power on the Go: Tips on Portable Power Supplies

Written on February 28, 2017 at 11:06 am, by

Although power supplies are most often used in a single location, such as a design lab or a factory test station, there are times when portability is desirable. For example, you may not want to purchase a laboratory power supply with sophisticated computer-control features, such as the Sorensen XBT Series (see right), for every design […]
