High-speed conveyor systems are highly vulnerable to sudden power dips that can stop operations and cause material jams. The QUINT-BUFFER module provides an immediate 24 V DC energy reserve, keeping drives active long enough to complete movements or bring the line to a safe stop. Its selective fuse technology isolates only the faulted section, preventing the entire system from shutting down. This not only reduces costly downtime but also minimizes mechanical stress caused by abrupt restarts, ensuring smooth production continuity.
Robotic arms in automated assembly require precise, uninterrupted motion. Even short voltage sags can result in misaligned operations or component misplacement. The QUINT-BUFFER steps in instantly, maintaining stable voltage for servos and controllers until normal supply returns. With its ability to deliver full load buffering for fractions of a second and extended support for lighter loads, the module ensures robots complete their cycles or return safely to a home position. This protects both product quality and machinery while reducing unnecessary downtime.
Modern packaging machines rely on real-time data collection and process tracking. A sudden power loss can corrupt records, miscount packages, or disrupt labeling operations. By supplying temporary energy during interruptions, the QUINT-BUFFER allows controllers to finalize data, finish ongoing cycles, and execute orderly shutdown sequences. Its monitoring outputs and clear status indication give operators immediate awareness of system health. With high efficiency during normal use, the module also minimizes energy loss and heat inside compact packaging enclosures, supporting both reliability and longevity.
Medical imaging devices depend on uninterrupted, stable power to deliver accurate diagnostic results. Short supply drops can distort images or interrupt patient scans. The QUINT-BUFFER ensures a constant 24 V rail, instantly bridging disturbances without the need for bulky batteries. Its selective fuse function prevents single branch faults from affecting the entire system, preserving uptime of critical medical electronics. This reliable buffering helps safeguard sensitive diagnostic equipment, protecting data integrity and patient safety in environments where every second of continuous operation matters.
