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 […]

Analog control for a power supply still a good choice for many applications

Written on November 2, 2016 at 6:33 am, by

While these days, computer control is usually the preferred method of controlling a power supply, many AMETEK Programmable Power products, such as the Sorensen SGA Series still offer analog control. Analog control is still used in many industrial applications, and it’s also a good choice if you have fairly simple control needs. The SGA Series […]

Power Source Multi-Box Configurations Meet a Variety of Needs

Written on October 25, 2016 at 11:17 am, by

Many of AMETEK Programmable Power’s AC power sources are designed to work as both standalone units and in multi-box configurations. The California Instruments iX Series AC/DC power sources, for example, includes independent 5 kVA power modules that can be combined into a number of configurations. You might use a single unit as a high-power, single-phase […]

Introduction to IEC 61000-4-11, Part II – AC source requirements

Written on August 2, 2016 at 7:04 am, by

In Part I, we introduced you to the concept of testing equipment for immunity to voltage dips and short power interruptions in accordance with IEC 61000-4-111. In addition to specifying the test waveforms, the standard also specifies AC source requirements for full compliance testing. Most of these requirements are easily met by the California Instruments […]
