Asterion makes harmonic analysis easy

Written on September 25, 2017 at 12:07 pm, by

Power systems operate at frequencies of 50 or 60Hz, but some devices, including personal computers, printers, and some industrial equipment, present a non-linear load and create currents and voltages with frequencies at harmonic frequencies. These harmonics get fed back into the power system and can cause other devices connected to the power source to malfunction. […]

Get the Rev Right When Running MIL-STD-704 Test

Written on July 25, 2017 at 1:46 pm, by

As noted in an earlier blog post, the tests you run to ensure that airborne utilization equipment is compatible with an aircraft’s power system are specified in a series of MIL-HDBKs, specifically MIL-HDBK-704-1 through MIL-HDBK-704-8. To run these tests, a sophisticated power source is essential to simulate various power conditions. In addition, you also need […]

RS Series high-voltage option eases PV inverter testing

Written on July 14, 2017 at 8:02 am, by

As the number of photovoltaic power-generation systems continue to increase, the requirements for photovoltaic inverters are evolving as well. Conventional electrical characteristics such as over-voltage, over-frequency, anti- islanding intended to verify the inverter’s ability to tolerate power grid fluctuation are changing to meet varying requirements of the modern grid. In addition, the introduction of new […]

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 […]
