Series AT
Reversible three-phase autotransformer
Series AT
Reversible three-phase autotransformer
Protection rating according to installation requirements:
- IP00 without enclosure
- IP23 enclosure for indoor use
- IP65 enclosure for outdoor use.
Features
- The most economical and efficient device for adapting a different voltage between the mains and the equipment.
- It allows the supply of single-phase loads in networks without neutral, with a maximum unbalance between phases of 10%.
- Robust and complete varnishing protects against humidity, dust and corrosion.
- IP20 terminal connection protects against direct voltage contact, up to 31kVA in IP00/23 and 25kVA in IP54.
- Optional cURus marking according to UL up to 100kVA for IP00.

Uses
As a booster or reducer adapting the voltage between the electrical network of the country where an industrial machine manufactured in a country of origin with a different voltage is installed.
To increase the voltage in long-distance power transmission to reduce resistance losses in the conductors.
Optionally, voltage changes with regulating sockets to compensate for the voltage drop in the cables of the installation.
