Dry Type Distribution Transformers
Drive Isolation Transformers: 7.5–440 kVA, Three Phase
Special Voltages and kVA Sizes for Drive Applications
For SCR (Silicon Control Rectifier) variable speed motor drive
applications, a transformer is needed to magnetically isolate
the incoming line from the motor drive. The transformer
must also provide a voltage change to match the required
voltage of the SCR Drive. Standard designs are delta primary
and wye secondary to match the common power sources
required in most three phase rectifier circuits.
SolaHD Drive Isolation Transformers are specifically
designed to handle the mechanical stresses, voltage
demands and harmonics associated with SCR applications.
Applications
• SCR Variable Speed Drives
Features
• Available from 7.5 thru 440 kVA, 3 Phase, 60 Hz
• Isolation minimizes load disturbances caused by the
SCR drive
• UL Listed/NEMA Type 3R enclosures when used with
optional weather shield
• Taps on all units for adjustments to incoming source
voltage. Full capacity secondary neutral as required
by the National Electric Code
• Shielding attenuates line to ground noise
• 10 year limited warranty
