Testing Procedures
Cefem Power conducts various tests including DC/AC saturation (single-phase and three-phase), load tests, partial discharge, dielectric, and temperature tests to ensure product reliability and performance.
Technical Capabilities
The magnetic components are designed for electrical signals up to 120 kHz and power ranging from a few dozen VA to 250 kVA. The company’s research department can handle special applications, offering integrated magnetic components, PCB-mounted components, and ready-to-mount components.
Development and Collaboration
For both project-based and serial manufacturing, Cefem Power collaborates with clients to study specifications and develop prototypes. This process allows for design validation and improvements before full-scale production.
