Modern railway systems rely heavily on a dependable 24 V supply for onboard electronics, signaling, and safety devices. Long cable runs often lead to voltage drops, and sudden startup currents from motors can destabilize the system. The QUINT4-PS/24DC/24DC/20/SC ensures a consistent power supply by using its dynamic boost capability to overcome inrush demands. Its selective fuse breaking isolates faulty circuits quickly, preventing disruption to vital controls. Designed to endure shock, vibration, and wide temperature ranges, this converter keeps rolling stock systems running smoothly. The result is improved passenger safety, reduced downtime, and a more reliable power backbone for railway operations.
In automated production lines, even short power interruptions can stop conveyors, robotic arms, or sensor networks. Voltage drops across long runs and sudden load peaks are common challenges. The QUINT4-PS/24DC/24DC/20/SC stabilizes control voltages and supplies enough reserve power during peak demand thanks to its static and dynamic boost functions. Preventive function monitoring gives operators early warning of potential faults, allowing maintenance before failures disrupt operations. With high efficiency and compact DIN-rail mounting, it integrates seamlessly into modern control cabinets. This ensures factories maintain continuous throughput, minimize costly downtime, and achieve greater energy efficiency during demanding production cycles.
Photovoltaic installations and other renewable systems often require reliable low-voltage power for monitoring equipment and communication devices. Harsh outdoor conditions, fluctuating input voltages, and the need for electrical isolation demand a robust solution. The QUINT4-PS/24DC/24DC/20/SC addresses these challenges with its high efficiency, protection against overvoltage, and fast fuse-breaking capability. By securing sensitive monitoring electronics, it prevents faults from spreading across the system. The converter also enables smooth parallel operation for redundancy, increasing reliability in large solar or energy storage arrays. This guarantees stable monitoring and control, ensuring maximum uptime and safer operation in renewable energy applications.
