Choose the Right Gauge Wire 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 wire will ensure that your power source will operate efficiently and reliably. The tables below will […]

Ensure Avionics Reliability with MIL-STD-704 Tests

Written on June 8, 2017 at 12:20 pm, by

To ensure that aircraft electronics and other electrically-powered equipment will operate reliably once in the air, you must test them under extreme power conditions. In the military world, MIL-STD-704 (now up to rev. F), “Aircraft Electric Power Characteristics,” establishes the requirements and characteristics of aircraft electric power. This standard is not only used by the […]

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 […]

New AC/DC Power Source Makes Three-Phase Power More Affordable

Written on May 15, 2017 at 9:56 am, by

SAN DIEGO, April 4, 2017 – AMETEK Programmable Power has added a 22.5 kVA unit to its popular California Instruments MX Series II AC/DC Power Sources. The MX22.5 delivers up to 22.5 kVA and can be configured to have single-phase or three-phase outputs in AC, DC or AC+DC mode. The MX22.5 is more economical than […]

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 […]

Calculate voltage drop to prevent system problems

Written on January 20, 2017 at 12:24 pm, by

One of the problems we frequently encounter in the field is that power supply users fail to take into account the voltage drop in the wires connecting a power supply to a device under test (DUT) or other electronic system. When a load draws a high current, the voltage drop across the power leads could […]

Know your power supply jargon: resolution and accuracy

Written on January 10, 2017 at 7:35 am, by

Two terms that often get bandied about when describing automated test systems are resolution and accuracy. To get the best results from your power supplies, it is important to understand the difference between these two specifications and how they affect your system. The New Oxford American Dictionary defines resolution as, “the smallest interval measurable by […]

Control options abound for Programmable Power products

Written on December 15, 2016 at 7:00 am, by

One of the most common applications for AMETEK Programmable Power power sources is some kind of automatic test system. The California Instruments Asterion AC Series, for example, was designed to be used in commercial and military avionics test system, manufacturing and process control, and IEC standards test systems. It includes Ethernet, USB and RS232 standard […]

Know your power supply jargon: watts vs. volt-amperes

Written on December 5, 2016 at 10:56 am, by

To select the right power source for your applications, one of the first things that you must do is to figure out how much output power you need. For a DC supply, this is relatively straightforward. You first determine the highest output voltage you’ll need and then the highest output current that you’ll need. The […]
