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
