Overview
3-Phase 480V Delta to 240V Delta
This industrial-grade transformer is engineered to convert 3-phase 480V to 3-phase 240V, making it ideal for powering equipment such as:
- Panels and control systems
- Motors and CNC machines
- Welders, conveyor systems, and pumps
- Printing and fabrication equipment
- Cryptocurrency miners and data center infrastructure
- Other commercial and industrial machinery
Electrical Specifications
- Primary Voltage: 480V Delta
- Secondary Voltage: 240V Delta / 120V (via center tap)
This model features a center tap (also known as a lighting tap) that provides single-phase 120V power from the secondary side. The 120V output supports up to 5% of the transformer's total kVA rating without affecting its overall capacity.
Reverse Feeding Capability
This transformer can also be reverse-fed to step up from 240V to 480V. However:
- Adjustment taps will not function in reverse-feed applications
- Inrush current will be higher than with a purpose-built step-up transformer
