Mr. Erdl, which power supply technologies do you consider to be essential in the coming years?
Bernhard Erdl: From the user’s perspective, I see great potential in using the power supply more as a source of information. It is the interface between AC and DC, in other words between the outside world and the inside of a system. Reliable and high-quality data on the actual state of a system can be obtained there.
Meanwhile, almost every device in the control cabinet has been digitized and provides data. Don’t you see the risk of a data overkill?
It is important that this data is managed centrally and that the user knows what he is able to do with it. The information provided by our new QT40 with IO-Link interface can be used by the customer, for example, to optimize his system, to maintain it preventively and ultimately to save money. This is a very significant added value we can offer.
How do you develop connected power supplies?
We develop our connectable power supplies and digital services in close collaboration with our customers using many different design thinking approaches, such as prototyping. If users are involved right from the start, we receive valuable feedback and create solutions that save them a lot of work. Connectivity is important, but it must also be “simple” for the user. Frost & Sullivan has already awarded us the Manufacturing Leadership Award this year for this user-focused strategy.
What other technical advancements do you consider to be relevant?
Another trend that we are observing is the rising demand of energy in all industries. Efficient power supply solutions for high power loads in the kilowatt range are increasingly being sought after. This is certainly a market with great potential, in which we will be playing a stronger role.
Can you give us an example?
In a customer-specific project we recently developed a modular and cost-efficient 32 kW solution. Four 8 kW power supplies are operating in parallel. Due to the high efficiency of up to 96% and a sophisticated thermal design, the whole system is still completely convection cooled. This example shows quite well that optimizing the core features of a power supply must always be kept in mind. These are primarily efficiency, lifetime, reliability and compact design. Every new feature is worthless if these core features are compromised.
Which role does the development team in Vienna currently play, which Puls took over from Artesyn in 2017?
Because of their Artesyn background, these 30 developers bring in a lot of knowledge and experience in the telecommunications industry. This helps us, for example, with the previously mentioned communication interfaces in the area of Industry 4.0. Additionally, Puls is getting completely new capabilities, as the development team grows from 70 to 100 experienced developers in one single step. And of course, our customers will also benefit from this increased competence and capacity.
What other plans do you have for the Vienna facility?
Our Vienna office is not really a location in a traditional sense. We call it an innovation lab because there we are testing new concepts and techniques during development. Approaches that work well will be adopted worldwide. As a result, we gain more flexibility and speed as a company. All of this has a real start-up dynamic, which we would like to maintain.
