Functions and uses of our three-phase transformer 400 230
This transformer is designed to transform a 3 x 400 V voltage into a 3 x 230 V supply and/or generate a neutral point when it is not available.
It is particularly suitable for industrial, tertiary installations or automation requiring galvanic separation to improve network safety and reliability.
Thanks to their versatility and proven reliability, these three-phase isolation transformers are used in a multitude of sectors.
They are used in industry as well as in environments requiring high electrical stability or reinforced equipment protection.
Common areas of application include:
- Aeronautics and aviation: secure power supply for test benches and ground equipment.
- Industry and production: protection of machine tools, automation, drives, and production lines.
- Medical sector: isolation of sensitive equipment and maintaining power quality in critical environments.
- Automation and robotics: power stability for PLCs, robots, and control systems.
- Tertiary buildings and technical infrastructure: reduction of electromagnetic interference in complex electrical networks.
And more generally, in any environment requiring galvanic separation, neutral creation, or improvement of energy quality.
Technical advantages of the three-phase isolation transformer
- Reduction of harmonics and electromagnetic parasites, for more stable operation of your equipment.
- Elimination of residual voltages on the neutral: in this case, the neutral must imperatively be connected to earth to guarantee optimal potential stability.
- Total galvanic isolation between primary and secondary, limiting risks of current return or disruption.
- Robust and ventilated construction in IP23 IK08 metal enclosure, suitable for demanding environments.
- Customization possible: power, voltage, adjustment taps, mounting accessories, or custom enclosure. Access the configurator >> Three-Phase Transfo Creator

Coupling of the 400V 230V + N transformer
The standard coupling of our three-phase transformer 400 230 + N is DYN11 (delta on the primary, star + neutral on the secondary). Other couplings are possible according to your needs, please contact us for any wiring different from DYN11.
