“EI”, “UI”, and “3UI” laminated or cut strip core transformers are available in both dual-coil (separating/isolating) and autotransformer designs. Power ranges from 50 VA to 125 kVA for single-phase units (higher on request) and from 100 VA up to 4000 kVA for three-phase units. Operating voltages reach up to 11 kV depending on design, with frequency options from 47 to 400 Hz.
All transformers are built with dry-type insulation systems in standard temperature classes. IP00 open construction can be supplied with enclosures rated up to IP23 or IP54, or in fully customised housings. Cooling options include natural air or forced-air configurations, ensuring reliable performance in a wide range of applications.
Applications
Our 1- to 3-phase transformers are used in a variety of demanding environments where reliable power conversion and electrical safety are essential. Their robust design and flexibility make them suitable for both standard installations and highly specialised systems.
They are widely applied in:
- Industrial machinery and motor drives
- Automation and robotics systems
- Renewable energy installations (solar, wind, storage)
- Rail and transportation equipment
- Marine and offshore power systems
- Medical electrical equipment
- Data centers and critical IT infrastructure
- General power distribution and conditioning
