• 15 kW power on A4 format
  • Liquid cooling
  • Parallelization of modules up to 120 kW
  • Current or power regulation.

Starting point

A company is asking us to take over and improve the functionality of its power converter and also to ensure its production.


15 kW in a ultimately very small footprint: 200 x 120 x 340 mm.


On the same cold plate, two converters (30 kW) can be coupled. These converters can be supplied with three-phase 200 or 400 V depending on the model.

Know-how on power converters

Customer issues

A Montpellier company specialized in the supply of equipment for laboratories and semi-conductor, photovoltaic and nanotechnology industries has called upon our expertise in the field of energy conversion.

EFS answers

EFS has been manufacturing power converters for several many years. Its experience in this field has made it possible to improve the functionality of a customer’s power converter and to repeatedly manufacture the EFS 8215-200 (200 V) and EFS 8215-400 (400 V) models. These are primarily compact and high-power power supplies.


  • suitable for supplying halogen lamps (dynamic impedance adaptation) for the thermal treatment of silicon wafer (wafer) in the semiconductor industry.
  • compact size (200 x 120 x 340 mm).
