Applications
- TTDN transformers are the ideal solution for safely adapting the output voltage of solar inverters to a grid voltage suitable for the installation, reducing the voltage from 400 V to 230 V.
- Are used for galvanic isolation of three-phase solar installations.
- Changing the neutral system of an installation
- They help improve the quality of the electrical network on the secondary side, especially in installations with a certain level of electrical noise.
Available accessories
- Protections in primary and secondary.
- One, two and up to 3 electrostatic screens.
- Class II
- Wheels.
- PT100, PTC or Bimetallic probes.
- Painting C5.
- Different RAL.
- Temperature control unit
- Anti condensation system
- Different IP up to IP-65
