Modern warehouses rely on high-speed conveyors and robotic sorting, where frequent motor starts create sudden current peaks. The QUINT-PS/3AC/24DC/20/CO meets these demands with its POWER BOOST reserve, providing up to 1.5 times the rated current for smooth acceleration of multiple drives. At the same time, its SFB technology ensures that only the affected circuit trips during a fault, keeping the remainder of the system fully operational. This combination reduces downtime, prevents costly stoppages, and supports the seamless flow of goods in demanding logistics centers.
Solar and wind energy installations often face fluctuating supply conditions caused by environmental changes. The QUINT-PS/3AC/24DC/20/CO addresses this by offering a broad input voltage range and extended buffering time, which keeps the DC bus stable even during short interruptions. Preventive function monitoring gives early warnings of irregularities, allowing technicians to take corrective action before failures occur. By stabilizing critical control circuits, the power supply helps renewable energy systems maintain reliability, efficiency, and grid compliance in variable operating environments.
In chemical plants, refineries, and heavy manufacturing, control systems must withstand corrosive gases, high humidity, and fluctuating loads. The QUINT-PS/3AC/24DC/20/CO features a protective coating that shields electronic components from harsh atmospheres, while high conversion efficiency minimizes heat stress. With built-in diagnostic monitoring, operators are alerted to unusual conditions early, reducing the risk of unplanned shutdowns. This resilience makes it ideal for supplying stable 24 V power to sensors, actuators, and controllers in critical process automation applications.
Railway signaling and traffic control infrastructures demand absolute reliability, as any power disruption can compromise safety. The QUINT-PS/3AC/24DC/20/CO delivers fast circuit breaker tripping through SFB technology while ensuring continuous operation of unaffected circuits. Its ability to run in redundant setups provides an additional layer of security, guaranteeing uninterrupted supply even if one unit fails. With wide operating temperatures and robust construction, it ensures safe and stable power delivery for mission-critical transport systems that cannot afford downtime.
