Technical Architecture & Functional Positioning

This infeed power supply sits at the energy supply layer in modular drive architectures, converting three-phase mains to a regulated DC bus that powers multiple drive controllers and inverters. It forms the backbone for scalable systems, where one unit can support numerous axes sharing a common bus, reducing overall wiring and component count compared to individual supplies.

The design leverages advanced IGBT-based rectification with active power factor correction and regenerative braking capability. Smart Energy Mode dynamically maintains the DC bus at a precise 700 V level, regardless of input variations or load changes. This technology addresses real-world issues like voltage sags in weak grids or energy recovery during deceleration, feeding excess power back to the mains rather than dissipating it as heat. In high-inertia applications, this cuts energy costs by up to 30% and eliminates the need for external braking resistors, simplifying installation and reducing cabinet space.

From an architectural view, the integrated control electronics handle communication over the module bus, enabling coordinated operation with drive controllers for functions like DC bus sharing and synchronized fault responses. Built-in diagnostics monitor parameters such as temperature, current, and voltage, isolating faults to prevent cascading failures. This is essential in continuous processes where downtime translates to significant losses, providing engineers with predictable performance and easier troubleshooting.
