2 If this information is unavailable, use the table below as a guide for selecting the transformer kVA for a required motor PHASE, DRIVE ISOLATION TRANSFORMERSWith today s technological advances in solid-state power control devices, the use of AC and DC variable speed drives has proliferated in many industrial markets. General purpose distribution transformers are not adequate for this type of DRIVE ISOLATION Transformers are designed to meet the rugged demands of both AC and DC variable speed drives and also to provide the required voltage change. The separate primary and secondary windings provide electrical ISOLATION between the incoming line and the SCR load. The windings are designed to withstand overcurrent of 150% of the rated load for 60 seconds or 200% of the rated load for 30 seconds.

3 (A duty cycle of one start for every two hours is permitted.) DRIVE ISOLATION Transformers are sized to match STANDARD motor horsepower and voltage ratings. STANDARD sizes range from 5 to 600 HP in six STANDARD voltages. Non- STANDARD sizes and voltages are available upon request.
