Ventilated 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.
