Digital Product Passports and Power Electronics

Twenty years ago, the adoption of the Restriction of Hazardous Substances Directive 2002/95/EC (RoHS 1) was one of the driving forces mandating the electronics industry to look for alternatives to replace the tin-lead eutectic alloy which had been used for decades for soldering purposes. Since then many regulations have sprung up restricting the use of hazardous substances, and we are familiar with RoHS, REACH, TSCA and others.

The next time you fly, recognize that it is -40 degrees outside, you are traveling at 500 miles per hour, 6 miles high, and there is not enough oxygen to survive. There are several hundred systems keeping you alive, comfortable, entertained, and flying in this environment. Astronics is the expert providing the power to those systems.

Astronics - Advanced Electronic Systems (AES) serves global customers as the aircraft industry's electrical power experts, offering a breadth of power solutions for commercial transport, business, VIP, rotorcraft, and military aircraft.  The company offers airframe power systems as well as the in-seat power systems and outlets that keep passenger devices charged throughout a flight. Astronics AES customers include more than 280 airlines, all major aircraft manufacturers, plus a myriad of military manned and unmanned aircraft manufacturers and inflight entertainment providers. In short, Astronics provides the power systems that support the entire industry.


"At Astronics, innovation is in our core," explained Mark Peabody, President of Astronics AES. "We pioneered the in-seat power that passengers use while seated on a plane, and today there are more than a million seats outfitted with our product. Every day, our team members work side-by-side with customers to create exciting new technologies that, like in-seat power, will help transform the future of the flight experience."

To date, Astronics power engineers have generated dozens of patents for power systems on aircraft.

Astronics EMPOWER® in-seat power systems keep
passengers powered throughout a flight.

Astronics now offers wireless charging for embedding in
furniture and seat backs to charge the newest phones.

Driving Innovation in Aircraft Passenger and Crew Power Systems
Since launching in-seat power, Astronics has continued to innovate and expand its product line over the years. Today, major OEMS and airlines count on Astronics to provide the industry's most comprehensive, most certified, most widely deployed set of in-seat power solutions in the world.

"Recently we introduced USB Type-C outlets to serve laptops, phones, and other emerging devices powered by this new standard," Peabody said. "And what we're really excited about right now is wireless charging, where we're now able to provide inductive charging for the newest passenger devices. Creating this for the aircraft was a challenge where we had to satisfy stringent power and safety requirements, and today we're thrilled to say many first and business class seat manufacturers are implementing this new technology to service their most tech-savvy passengers."

Astronics in-seat power systems offer real-world impact on passengers and flight crews, enabling them to enjoy inflight entertainment and stay connected to loved ones throughout their journey without worrying about conserving device batteries.

Astronics is helping to drive the development of tomorrow's more electric aircraft.

On a Mission: To Drive the More Electric Aircraft
Astronics is also deeply involved with the industry drive to the more electric aircraft. From R&D efforts to thought leadership on emerging standards and solving technical issues, Astronics is creating products and systems for tomorrow's innovative aircraft. Astronics is supporting its longtime customers in new initiatives to bring more electrical systems to fixed-wing aircraft, rotorcraft, and now, the emerging class of electrical vertical take-off and landing (eVTOL) aircraft.

"We're thinking about the performance improvements that can be expected in transitioning to an aircraft where more systems are powered and monitored electronically. With our power systems, we're also incorporating smart sensing elements to help with vehicle health management and predictive maintenance. We're pushing power to do more than simply provide power -- we're excited to be introducing a whole new class of intelligent power systems for the evolved aircraft of tomorrow," Peabody said.

For airframe power, Astronics manufactures power generation, power conversion, and power distribution products. Incorporating the latest solid-state technologies and designs, these systems deliver highly efficient, clean electrical power that improves aircraft operation through weight and system wiring savings.

Astronics' starter generator units form the foundation of a more electric airframe power system.

PSMA Expands Engagement with Young Professionals and Women in Engineering at ECCE 2022

Building on the success of participation in the Young Professionals (YP) social event and Women in Engineering (WiE) roundtable breakfast at this year's Applied Power Electronics Conference (APEC) in March of 2022, PSMA continued efforts to increase engagement by participating in both  events during the 2022 Energy Conversion Congress & Expo (ECCE)  held Oc

Message from the PSMA Executive Committee


Without a doubt we are approaching the end of a quite different and challenging year not only for our organization but also for all our member-companies and individuals who support, participate and volunteer for PSMA.  As the world and businesses continue adjusting to a new pandemic-imposed reality, PSMA not only confronted the challenges, but with creative and agile support of its numerous volunteers, the dedicated people who run the office, the board and the executive committee,  co-sponsors and partners responded with agility and creativity to minimize financial loss and risk, while maintaining the valuable services to its members and the community.

We at the executive committee are excited to implement and work in alignment with the newly adapted four pillars of our organization: (i) build on strengths, (ii) become more applications oriented, (iii) integrate performance metrics to assure value add to our community, and (iv) engage with the stakeholders.  Using these guidelines, we hope to drive success and growth of a more vibrant, more active, and more relevant PSMA.

As the member of the executive team who champions the third pillar, the implementation of key performance indicators throughout the operations and activities undertaken by PSMA, I hope to establish a measurable understanding of the "value-add" to "asset allocation" ratio in order to prioritize and improve the effectiveness of our efforts and resources.  Ahead of us is another financially challenging year and this task is critical for sustaining short- and long-term financial viability.

Some of the areas that we plan to implement performance metrics so that we can better understand impact on growth and revenue include:  membership movement comparable to the number of professionals in the industry, web activity tracking, differentiation and consumption of PSMA exclusive offerings such as special projects, reports, databases and other contributions as well as feedback received on our activities. 

We also plan to apply these metrics to activities related to popular workshops and webinars to maximize the value to our members and the wider power electronics industry, return on investment and exposure for PSMA. Remember, as a not for profit organization of volunteers, we need to spend our income from memberships, studies, and events prudently and maximize the use of in-kind human capital from our volunteers. We hope to expand the key performance indicators across the whole organization for example to support and help optimize the numerous committee efforts so as to attract more participation and increase activity.

The Executive Committee will not be able to establish, build and strengthen the performance metric pillar to become an impactful potency without the support and the collective effort of all the members and the volunteers of our organization.  We are encouraging all of you on an ongoing basis to provide feedback, thoughts, and new ideas as we continue to grow a successful PSMA.

Please feel free to contact me or any of the executive team members or the PSMA office anytime. We would love to hear from you and need your inputs!
