Functions and uses of our 400 230 three-phase transformer
This transformer is designed to transform 3 x 208 V into 3 x 400 V supply and/or generate a neutral point when it is not available.
It is particularly suitable for industrial and commercial 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 enhanced 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 maintenance of power quality in critical environments.
- Automation and robotics: power stability for PLCs, robots, and control systems.
- Commercial 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 noise, for more stable operation of your equipment.
- Elimination of residual voltages on the neutral: in this case, the neutral must absolutely be earthed to guarantee optimal potential stability.
- Total galvanic isolation between primary and secondary, limiting the risk of current return or disturbance.
- Robust and ventilated construction in an IP23 IK08 metal enclosure, suitable for demanding environments.
- Customization possible: power, voltage, adjustment taps, fixing accessories, or custom cabinets. Access the configurator >> Three-Phase Transfo Creator

Coupling of the 208V 400V + N transformer
The standard coupling of our 208 400 + N three-phase transformer is DYN11 (delta at primary, star + neutral at secondary). Other couplings are possible according to your needs, please contact us for any wiring other than DYN11. The phase-to-neutral voltage at the secondary is 230V.
