Powernet
Power Supplies and Converters for Railways


Powernet designs and manufactures custom-design solutions for demanding power conversion applications. Over the years, we have become a well-known and trusted supplier of highly efficient, high-reliability power supplies and converters in Finnish and European markets.
Powernet’s success is based on our extensive research and development combined with strong sourcing and manufacturing competence. We offer the full service from research and development to prototyping, extensive testing, manufacturing and lifecycle management of the products delivered.
The company is based in Vantaa Finland with a highly skilled R&D team and a partner network, including the best EMS companies in the Nordic region.
Powernet is experienced in engaging our clients in specific products based on proven platforms designs and in addition has an extensive portfolio of standard power supplies to offer. Our goal is to be the chosen long-term power supply partner for our customers.
Rail approved auxiliary power ADC9000 – modules 500W-3,200W
Powernet’s ADC9000 series design platform covers the power supplies, converters and battery chargers from 500W-3,200W with rail approvals according to EN50155. Final products will often be optimised in co-operation with our clients.
This is a perfect combination of the latest design knowledge and the individual needs of each client.
The ADC9000 series module family currently offers the following solutions:
- AC / DC 500W power supplies and chargers (230VAC / 24VDC)
- DC / DC 500W converters (24VDC / 36VDC / 110VDC – 24VDC)
- DC / DC 1kW converters (24VDC / 36VDC / 110VDC – 24VDC)
- DC / DC 1,5kW converters 110VDC / 24VDC
- AC / DC 3kW 3-phase 400VAC / 24V or AC 3-phase 400VAC / 110VDC
- DC / DC 3,2kW converters 110VDC / 24VDC
MSR9800 battery management systems 3kW-20kW
Combining several ADC9000 modules into a battery management system, the MSR9800 system offers solutions from 3kW-20kW, including customized charging algorithms, temperature compensation and CAN bus interface. Integrating the MSR9800 with the train management system battery condition and charging rates can be monitored centrally.
Also, with a modular approach n+1 redundancy is achieved by installing one extra module in the system. The MSR 9800 is designed using a 2in x 19in rack width. Higher power (n x 3,2kW) can be obtained by connecting several units to the system or even several systems to each other.
Versatile trackside solutions
Powernet’s standard products have been used in trackside communication systems and railway crossing systems since 2000. The ADC5000-series power supplies and battery chargers offer a very reliable and proven solution with some 30 versions to choose from. For particularly harsh environments, the units are offered ‘ruggedized’ with both conformal coated PCB and silicone glue to support the main components against vibrations.
Powernet DAC60000 – inverters offer a high-end backup solution to convert battery power (24VDC / 48VDC / 110VDC / 220VDC) to high quality sinusoidal 230VAC. The DAC6000 family is highly modular and covers power ranges from 1.5KvA (one unit) up to 90kVA featuring also modular static switches and By-pass units.
