Rotary phase converters (RPC)
Three-phase power for suitable applications
AST provides rotary phase converter solutions for suitable applications where three-phase power is required but only a single-phase supply is available.
A rotary phase converter uses a motor-based conversion system and associated electrical equipment to generate a third phase, enabling compatible three-phase machinery to operate when correctly selected and installed.
Typical applications
- Lathes and machining equipment
- Saws and drilling machines
- Presses and workshop machinery
- Selected pumps and irrigation equipment
- Suitable welding and plasma-cutting equipment
- Commercial and industrial machinery
Sizing comes first
AST assists customers with equipment selection, load assessment and installation planning. Correct sizing is essential, particularly for machinery with high starting currents or demanding operating requirements.
Important application note
Certain high-pressure pump and constant high-pressure compressor applications may require an appropriate auto delta-star starter or another suitable engineered solution. Consult AST before connecting these loads.
