Product Overview:


The CTT.A is the most economical solution that supplies the most undisturbed power to the related equipment or area. It is a three phase autotransformer with natural convection of air as the cooling method. 

The CTT.A is designed with low loss core material that results in dramatic drop of the inrush current. The inrush current of CTT.A is typically between four to six times its rated primary current. Although autotransformers are not regulated to meet certain efficiency levels or standards, but Synergy Energy Inc.; as one of the pioneers of high efficiency dry-type transformers; continues to raise the bar for all transformer manufacturers in improving their products and designing transformers with lower loss and higher efficiency. The CTT.A is a perfect example, as the core steel used in its production is of special design; grain oriented and annealed to provide a high flux density and improve the efficiency. 

When compared to a regular autotransformer, the CTT.A offers 30% less no-load losses which puts it amongst the most efficient products in the industry and a very low period for returning the original investment. Another advantage of the CTT.A is its small footprint which makes it installation in confined spaces possible. This is usually the case with imported equipment that require a different operating voltage. 

The CTT.A design configuration allows for having a neutral connection point. Therefore, CTT.A can accommodate any electrical system with 3 phase; 3 wire or 3 phase; four wire on its primary and/or secondary side. All of the connection points of the CTT.A can be accessed through its removable front panel. It is capable of accepting a wide variety of additional options.

The CTT.A in its standard form has a maximum temperature rise of 150 °C.

The finished product is shipped in a shrink-wrapped, gray NEMA 3R enclosure with corner protectors on our unique SmartSkid®, for safe and effortless transportation and installation.
