Series TTH
Three-phase high power transformer
Series TTH
Three-phase high power transformer
Three-phase transformer with galvanic isolation between primary and secondary of high power.
Cylindrical windings and 45º staggered cores.
Protection rating according to installation requirements:
IP00 without enclosure
IP23 enclosure for indoor installation
Features
- Eliminates the risk of accident in case of unipolar contact.
- Foil windings to minimise load losses.
- Anti-flash treatment to protect against humidity, dust and corrosion.
- Magnetic core 45º Step-lap technology to reduce no-load losses and magnetising current.
- Optionally for IP00 possibility of cURus marking according to UL insulation system.

Uses
For general use as isolation and circuit isolation transformer.
For recirculation transformer in converter test benches.
For voltage change as a step-up or step-down to adapt the voltage between the grid and the equipment in photovoltaic inverters.
Generation of our isolated IT or neutral to earth TN-S and TN-C systems to avoid unwanted tripping of earth leakage circuit breakers.
