The Phoenix Contact QUINT-PS/3AC/24DC/20 is a high-performance industrial power supply that provides a stable 24 V DC output at 20 A. Built with advanced Selective Fuse Breaking (SFB) technology, it ensures rapid circuit response to protect downstream devices and minimize system interruptions. Its preventive monitoring system continuously checks critical parameters, giving early warnings before failures occur. With an adjustable voltage range and the POWER BOOST reserve for starting heavy loads, this compact supply is designed for robust and reliable operation in automation, process control, and other demanding environments.
This QUINT series model combines efficiency, protection, and flexibility to meet modern automation requirements. The SFB function allows circuit breakers to trip quickly, preventing wide system shutdowns and lowering downtime costs. Preventive diagnostics improve operational security by signaling irregular conditions early. The POWER BOOST capability delivers additional current to reliably start motors or large inductive loads, while the adjustable voltage output adapts to different applications. Its durable design ensures long service life even under tough industrial conditions, making it an essential choice for manufacturers who prioritize productivity and system availability.
The QUINT-PS/3AC/24DC/20 stands out as more than just a power supply—it’s a reliability booster for critical automation. With its rapid fuse-breaking response, POWER BOOST reserve, and early-warning monitoring, it guarantees stable performance where downtime is not an option. Its compact yet robust design ensures consistent operation, even in the toughest industrial settings.
Unplanned shutdowns and unstable load startups are major risks in automation. The QUINT-PS/3AC/24DC/20 solves this by delivering selective circuit protection, dependable current reserves for heavy loads, and intelligent monitoring that detects faults before they escalate. It reduces costly downtime, prevents equipment damage, and keeps complex industrial processes running smoothly and efficiently.

Traffic management systems rely on uninterrupted power to keep lights, sensors, and controllers working flawlessly. The QUINT-PS/3AC/24DC/20 ensures stable operation by providing fast circuit protection that isolates faults without shutting down the whole system. Its POWER BOOST capability delivers the extra current needed for sudden load surges, such as when traffic signals or detection loops activate. This level of reliability reduces risks of downtime, keeping roads safe and traffic flowing smoothly.
Automated assembly and packaging lines demand power supplies that can handle the high inrush currents of motors and actuators. With its POWER BOOST reserve, the QUINT supply supports heavy load start-ups without voltage drops that could stall equipment. Preventive monitoring functions detect irregularities before they disrupt production, giving engineers time to address issues proactively. The result is a stable, uninterrupted power backbone that keeps high-speed manufacturing processes running efficiently.
Industrial facilities such as wastewater plants or coastal operations expose electronics to moisture, vibration, and corrosive elements. The QUINT-PS/3AC/24DC/20 is designed to withstand these environments, with wide operating temperature tolerance and robust build quality. Its stable 24 V output ensures dependable power for pumps, sensors, and monitoring systems even under challenging conditions. By resisting environmental stress, it prolongs service life and prevents costly downtime in critical infrastructure.
Modern factories often run dozens of I/O modules and controllers from a single centralized supply. The QUINT’s adjustable voltage range helps compensate for voltage drops across long cable runs, ensuring consistent power at every endpoint. Its selective fuse breaking isolates only the faulty branch, protecting the rest of the PLC system from failure. High efficiency reduces heat build-up and energy costs, while predictive monitoring supports planned maintenance, making it an ideal backbone for advanced automation networks.
