Rail Auxiliary Power Supplies, Converters and Battery Chargers

Powernet is a trusted supplier of demanding power conversion solutions for transportation and industrial applications. Since 1992 we have produced hundreds of different power supplies for harsh conditions. Powernet is experienced in engaging our customers in customer specific products based on proven platforms designs and in addition has an extensive portfolio of standard power supplies to offer. Our rail approved solutions are certified according to relevant rail norms EN50155, including safety and fire approvals. Our goal is to be the chosen long term power supply partner for our customers. Powernet 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.

Rail Approved Power Modules

Launched in 2012, Powernet’s ADC9000 series design platform covers the power supplies, converters and battery chargers from 500W-3200W with rail approved power modules, according to EN50155. Final products will often be optimized in co-operation with our customers. This is a perfect combination of the latest design knowledge and the individual needs of each customer. The ADC9000 series module family currently covers the following needs:

  • 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 3phase 400VAC/24V or AC 3phase 400VAC/110VDC
  • DC/DC 3,2kW converters 110VDC/24VDC

Train Battery Management System

Combining several ADC9000 modules into a train battery management system the MSR9800 system offers solutions from 3-20kW, including customized charging algorithms, temperature compensation and CAN bus interface. With a modular approach n+1 redundancy is achieved by installing 1 module extra in the system. The MSR 9800 is designed using a 2x 19” 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.

Track Side Power Solutions

Powernet standard products have been used in track side communication systems and railway crossing systems since year 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 back-up 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 (1 unit) up to 90kVA featuring also modular static switches and By-pass units.

Train Power Converters

Powernet offers a unique combination of innovativeness and reliability based on proven platform designs in their train power converters. Powernet advantages include: -40°C to +55°C Ambient Temperature, Cold start at -50°C (reduced performance), Compact aluminium IP21 enclosure, Light weight, CAN bus interface, Rail approved (EN50155), GOST approvals (project specific)
