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 […]

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 […]

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 […]
