Frequently-asked questions about the Sorensen DLM 600 Series

Written on October 19, 2017 at 10:52 am, by

The Sorensen DLM 600 series of programmable power supplies is designed to provide continuously variable output voltage and current for a broad range of applications in a compact 1U (1.75 inches) high, half-rack (8.5 inch) wide chassis. The DLM 600 power supply series is ideal for high density, multiple output, rack-mount applications or low profile […]

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 […]

Choose the Right Gauge Wire Size for Your Application

Written on June 8, 2017 at 12:26 pm, by

When installing an AMETEK Programmable Power power source, you must properly size the wires you use to connect the AC input power to the power source and the AC or DC output to the load. Selecting the right size gauge wire will ensure that your power source will operate efficiently and reliably. The tables below […]

Modern Power Supplies Help Reduce Test Costs

Written on May 24, 2017 at 7:57 am, by

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 […]

Know Your Power Supply Jargon: Isolation

Written on May 24, 2017 at 7:51 am, by

Many AMETEK Programmable Power products offer isolated outputs. In this blog post, we’re going to discuss what power supply isolation means and why this characteristic is desirable. An isolated power supply has a power output that is electrically independent of its power input. That is to say that there is no connection between the power […]

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 […]
