Design and Manufacturing Approach:

Cefem Power is a preferred partner for both project-based and serial production, meeting specifications and optimizing designs.
The company employs a "Design To Cost" methodology to optimize product design and reduce costs while meeting customer expectations.
Mechanical integration is considered from the design phase, focusing on volume constraints, shape factors, and a Plug & Play system with a heatsink.

Technical Capabilities: Cefem Power's magnetic components are designed for electrical signals at frequencies up to 40kHz and power ranging from a few dozen VA to 250 kVA, specifically for railway applications.
