Magna-Power Electronics, Inc. was founded in 1981, initially focusing on developing customized power electronics and magnetic systems. Pressured by the rapid design cycles, Magna-Power Electronics developed a solid position in the designing and prototyping customized power supplies, and producing magnetic components in small volumes. Customers perceived good craftsmanship and demanded their designs in production quantities. In satisfying these desires, Magna-Power Electronics evolved into a production company.

Magna-Power Electronics applied its strength in power technique by using modular building elements in the production of DC power supplies. The building elements were made interchangeable, facilitating the configuration of systems to specific customer requirements. Investment in inventory and adapting products for system-oriented production, established Magna-Power Electronics as a leader in delivering high-performance and competitive DC power supplies.

The product portfolio consists of five series, ranging in power from 1600 W to > 2 MW. The voltage range varies from 5 V to 10.000 V, with current ranges from 0.2A to 24.000A.

In 2016, Magna-Power presented its MagnaLOAD electronic DC loads product line. This portfolio consists of three series, ranging from 1.25 kW to 120 kW+, with voltage ranges from 0 to 1,000 Vdc, and current ranges up to 1,200 Adc.

Types of models:
DC power supplies
DC loads

Magna-Power Electronics’ products are proudly manufactured in the USA. The headquarters in Flemington, New Jersey, are vertically integrated and company grafted on a parcel comprising over 6,800 square meters. The entire development, production, and service for North American customers is executed at the head office.

The vertical integration is used in the production process to maintain full control on quality, delivery, and cost of the customized products. Internal processes were added as the company expanded. The process currently includes, among others:

Research and development
Magnetic coil
– Production of magnetic core
– Full sheet metalwork
– Cable protection
– Powder coating
– Laminated bus bar manufacturing
– Production of air and water-cooled heat sinks
– Circuit board assembly
Final assembly, testing and burn-in

The vertical integration ensures that Magna-Power Electronics can produce an extensive line of high quality electronic products, yet realizing a lead time of three weeks for products ranging from 1.6 kW to 15 kW. Casing design teams and production teams operate at the same location, which allows for smooth team cooperation and continuous process and production improvements.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
