The Acme Drive Isolation Transformers are specifically designed to accommodate the special voltages and KVA sizes unique to AC and DC motor drive applications. Acme uses strip conductors (above 7.5 KVA) instead of wire for DIT series that easily accommodates the servere electrical and mechanical stresses found in today's AC & DC motor drives. The inherent excellent line isolation of these transformers is further enhanced with the extra protection of Acme's Electrostatic Shield ‑ Free in all DIT's.
The harmonic current generated by AC & DC drives increases eddy current losses (heat) in transformer windings. The thicker the winding conductor, the greater the losses. Acme uses one turn per layer of thin strip conductor which provides lower eddy current lossesthan comparable wire wound units. Lower losses equals cooler operation and longer transformer life. Strip windings minimize axial short circuit forces that can cause mechanical displacement of the windings under fault conditions. For extra protection all designs 7.5 KVA and above use primary and secondary coils of equal axial length. This feature tends to negate axial short circuit forces, further imporving transformer life expectancy.
