MOTOR DRIVE TRANSFORMERS

Motor Drive Transformer Models & Prices 

Our Motor Drive Isolation Transformers are specifically designed to meet the requirements of SCR controlled variable speed motor drives. They are ruggedly constructed to withstand the high mechanical forces associated with SCR drive 
duty cycles. The double-wound construction isolates the line from most SCR 
generated voltage spikes and transient feedback. These transformers also assist 
in reducing some types of line transient that can cause SCR misfiring.

UL Listed, File E78234.
CSA Certified, LR560.
Three Phase 3 - 145 kVA.
3 - 7.5 kVA are copper wound and equipped with a UL 200°C insulation system and a 115°C temperature rise. Windings connect to compression style terminals, eliminating the need to purchase additional connectors.
11 - 145 kVA are aluminum wound and equipped with a UL 220°C insulation system and a 150°C temperature rise. Windings connect to buss bar style terminations equipped with NEMA standard holes for user supplied compression style terminals.
NEMA-3R, ventilated, cabinet style enclosure suitable for indoor or outdoor use. No extra rainshields required for outdoor use.
Electrostatic shield between windings provides cleaner output voltage and helps to reduce spikes and transients.
Vibration dampening pads provide quiet operation.
Core and coil and nonstandard designs are available by consulting the Phase Technologies.
