In large production plants, conveyor belts and robotic arms often demand high current at startup, which can overload standard supplies. The QUINT4-PS/3AC/24DC/40/VASS handles these surges using its dynamic boost up to 60 A, ensuring smooth operation without nuisance trips. Its Selective Fuse Breaking technology isolates faults quickly, keeping the rest of the system running. With preventive monitoring, maintenance teams receive alerts before issues become critical, reducing unplanned downtime and ensuring reliable output for continuous manufacturing operations.
Automated warehouses rely on uninterrupted power for cranes, shuttles, and lifts. Using two QUINT4 units in a redundant setup ensures one supply can take over if the other fails. The static boost provides headroom when multiple devices start simultaneously, avoiding voltage dips. Configurable signaling through NFC helps operators set thresholds that match load demands, making system diagnostics faster and more accurate. This results in greater uptime, fewer bottlenecks, and stable performance across automated logistics operations.
Renewable energy systems face fluctuating inputs and exposure to electrical disturbances. The QUINT4 power supply stabilizes output for control electronics, protecting them from spikes with its integrated surge arrestor. Its wide input tolerance makes it suitable for grids in remote or unstable regions. Preventive monitoring features provide early warnings about overload or aging components, allowing service teams to act before faults cause shutdowns. This ensures reliable energy conversion and protects long-term investment in renewable infrastructure.
Remote monitoring sites and mobile infrastructure often rely on unstable power sources. The QUINT4 adapts easily with its broad AC/DC input range, delivering consistent 24 V DC to essential systems. Its mains buffering capability keeps critical loads active even during short power losses, while robust housing ensures durability under vibration and temperature changes. Configurable alerts allow engineers to optimize power supervision remotely, cutting down on costly service visits and keeping communication or monitoring systems continuously online.
