Product Description View more Close tab

With 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 application.

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. (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.

  • Ventilated, NEMA 3R Rated - Rugged design lets you install it where you need it whether that be indoors or outdoors.
  • Optional: NEMA 4, 4X (Stainless Steel) and 12 available
  • 3-6% Impedance
  • Thermostat Provided as Standard

What is a Transformer and How Does It Work?

Transformers change voltage through electromagnetic induction between the primary and secondary winding coils. This video illustrates the basics of how transformers work.
