MSc operations has started in 1985 as a small power converter manufacturer in Tampere, Finland.

Today MSc is formed by two companies; MSc Electronics Oy, that specializes in power converters for smart grid, renewable energy and industrial applications and MSc Traction Oy, that specializes in auxiliary power converters for rail vehicles.

The companies' headquarters and production are in Tampere, Finland.

By today MSc has delivered over 14 000 power converters and with over 30 years experience MSc products have proved their applicability and operational reliability in wide range of applications in global market. As an experienced power conversion expert MSc is a flexible and experienced partner who can quickly fulfill the requirements of the customer. With MSc converter solutions clients are able to improve their competitiveness independently of their applications.

MSc's solutions offer energy saving, improved energy efficiency, and decrease in operating expenses.

MSc is a notable cleantech pioneer.

MSc - Smart Grid

MSc bidirectional DC/DC converters, inverters and customized power converter solutions are the key parts of the different electrical energy storage- and renewable energy production systems.

HESS - Hybrid Energy Supply System

Hybrid Energy Supply System makes it easy to create an independent microgrid by connecting solar panels, modern diesel generators, and batteries. Microgrids are typically used in areas where centralized power grid is not available.

HESS automatically optimizes the energy supply by loading the batteries when there is more energy available from solar panels than the current need. Diesel generator is only started when the needed capacity is not available from either the solar panels or batteries.

Nominal power in one unit is 50 kW and 8 units can be connected in parallel. Output voltage is 380-480Vac (3-phase+N).

DC/DC -Converters

MSc bidirectional DC/DC converters have especially been designed for electrical energy storage applications and they enable the charge and discharge of the electrical energy storage.

Electrical energy storages based on different technologies such as lithium-ion, lead-acid, flow batteries, super capacitors and fuel cells can efficiently and effectively be controlled with MSc converters.

DC/AC -Inverters

MSc off-grid Inverter is a perfect solution for the microgrid applications.

MSc off-grid Inverters are capable to control and stabilize the output voltage even in supplying 100% unbalanced loads.

Inverters are based on the newest converter technology and they can easily be used as building blocs in 80-480Vac, 50/60 Hz, 3-phase microgrid applications.

Battery Energy Storage Systems

MSc Battery Energy Storage Systems will be designed and manufactured based on the customers needs in power range 50 kW - 500 kW.

MSc is capable to integrate different energy sources, batteries and power converters in complete power- and energy storage solution.

MSc will provide a turn-key solution for off- and on-grid applications.

Supercapacitor Energy Storage Systems

MSc is an expert in different supercapacitor-based energy storage systems.

The advantages of supercapacitors over batteries are their fast charge and discharge, the capacity to store a big amount of energy in a small space, and the fact that they are maintenance-free.

This technology is suitable for the recovery of braking energy and for the generation of peak power in different cyclically functioning devices in order to improve energy efficiency and to reduce fuel expenses.

Supercapacitors are also fit for short-term uninterruptible motor drives.

MSc has a wide experience in specialized different-sized supercapacitor-based energy storage systems, ranging from the energy storage systems in trams to hybrid drives of heavy-duty machinery, like mobile harbour cranes and short-term uninterruptible motor drives utilized in wind power plants and trams.
