Product Introduction
In heavy automated manufacturing layouts, automotive pressing lines, and large-scale printing facilities, multi-axis servo systems depend on a centralized, highly stable DC bus infrastructure to manage rapid load changes. The Bosch Rexroth REFURD41.1-6B-050L is an engineered 50kW power supply module built to convert incoming three-phase factory mains into flat, filtered DC voltage. This central DC link directly supplies separate, downstream inverter drives, allowing for efficient energy balancing—where breaking energy from one servo motor can be immediately consumed by a separate motoring axis on the same bus link.
Utilizing an exact-spec hardware block like this module during an emergency line down-time avoids the expensive and lengthy engineering required to re-program entirely new drive families. The chassis features heavy-duty internal commutation capacitors, integrated charging resistors to limit inrush currents, and localized thermal protection loops. When swapping out high-power supply gear, engineers must match the cooling style suffix (“L” for local liquid/forced air boundary layouts) to match the host enclosure’s ducting layout.
