Total cost of ownership is more than just price

Written on January 4, 2018 at 7:01 am, by

When you purchase a power supply, you need to take into account more than just the price of the supply. The price is just one of the factors in the total cost of ownership. Other factors include: sales and application support, ease of use, downtime for calibration, repair, and upgrades Sales and application support is […]

Easily program voltage and frequency transients with the Asterion Series

Written on December 4, 2017 at 10:26 am, by

The success of a product often depends on how well it can handle power transients. To make this testing easier, AMETEK Programmable Power’s Asterion makes it easy for users to create custom waveforms that include transients. The output waveforms can include any or all of the following transients: DROP. DROP causes the output voltage to […]

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 […]
