Introduction

Phoenix Contact has long been recognized as a global pioneer in industrial automation and power solutions, known for combining innovation with proven reliability. In modern industries, where every second of uptime counts, a dependable power supply is essential to keep automated systems operating smoothly. Even a brief voltage drop can disrupt production or damage sensitive equipment. The Phoenix QUINT 2320908 PS/1AC/24DC/5/CO is a compact yet powerful solution built to meet these challenges head-on. Designed for durability and consistent performance, it delivers stable 24V DC power even in harsh environments. This blog explores why this model stands out for performance, protection, and long-term sustainability.

Designed for Harsh Industrial Environments

The Phoenix QUINT PS/1AC/24DC/5/CO is specifically engineered to operate in environments where standard power supplies often fail. The “CO” in its name stands for Coated, referring to a special protective layer applied to the circuit board. This coating safeguards the internal components from dust, moisture, and corrosive gases, ensuring the power supply continues to perform reliably in tough industrial conditions. Whether used in chemical processing facilities, outdoor panels, or high-humidity areas, it maintains steady performance with minimal maintenance. The protective coating not only prevents corrosion but also significantly extends the product’s lifespan. Its rugged design ensures long-term stability and dependable operation even when exposed to the most demanding industrial settings.

Exceptional Reliability & Uptime with SFB Technology 

A major advantage of the QUINT PS/1AC/24DC/5/CO is its Selective Fuse Breaking (SFB) technology, which is designed to protect your systems from complete shutdowns. This technology allows the power supply to deliver up to six times its rated current for about 12 milliseconds, enabling it to trip faulty circuit breakers instantly while keeping other circuits running smoothly. That means if one part of your system experiences a fault, the rest continues operating without interruption. For industries that depend on constant uptime—like manufacturing plants, process automation, and utility operations—this feature is crucial. SFB technology not only isolates problems quickly but also reduces downtime, protects equipment, and improves overall system efficiency, giving engineers greater control and peace of mind.

Strong Output & Versatile Performance

The Phoenix QUINT PS/1AC/24DC/5/CO provides a stable 24V DC, 5A output, making it perfect for powering PLCs, remote I/O devices, sensors, and communication modules. It maintains a clean, low-ripple output (under 40 mVPP), ensuring stable performance even for sensitive electronics. Its Power Boost function allows it to deliver up to 1.5 times the rated current continuously, supporting devices with high inrush currents during startup. Engineers can also adjust the output voltage from 18V to 29.5V DC, allowing customization for different setups or specialized equipment. Whether you’re working with compact control panels or large automation systems, this power supply provides consistent, efficient, and flexible power delivery tailored to industrial needs.

Safety, Certifications & Global Compatibility

Safety and reliability are key priorities for Phoenix Contact, and this power supply reflects that commitment. The QUINT PS/1AC/24DC/5/CO meets a wide range of international standards and certifications, including ATEX, ANSI/ISA, and UL, making it suitable for use across the globe—even in hazardous or demanding environments. It includes short-circuit protection and up to 4 kV AC isolation between input and output, enhancing operator safety and equipment protection. Its wide input range (85–264V AC / 86–430V DC) ensures compatibility with different power networks around the world. The compact, DIN-rail mountable design allows for quick installation and efficient use of cabinet space, while also supporting excellent ventilation and easy accessibility for maintenance.

Preventive Diagnostics & Maintenance Benefits

Unlike conventional power supplies, the QUINT PS/1AC/24DC/5/CO offers advanced diagnostic capabilities that actively monitor output voltage and current. These diagnostics identify irregularities or overloads before they lead to a system failure. By detecting early warning signs, technicians can take preventive action to avoid unexpected downtime and costly repairs. The power supply also provides visual and signal-based indicators that simplify troubleshooting and maintenance. This predictive maintenance approach ensures smoother operations, longer equipment life, and fewer production disruptions. For industries that rely on efficiency and uptime, it’s a smart investment in both performance and peace of mind.

Energy Efficiency & Long-Term Sustainability

The Phoenix QUINT PS/1AC/24DC/5/CO is built with sustainability in mind. Operating at around 90% efficiency, it reduces energy loss and heat generation, which helps lower power costs and maintain cooler control cabinets. With a maximum power loss of only 15W, it minimizes energy waste while extending the lifespan of nearby components. The unit performs reliably in extreme temperatures—from -40°C to +70°C—and boasts an impressive MTBF (Mean Time Between Failures) of over 635,000 hours. This combination of efficiency, durability, and longevity makes it a highly sustainable choice for modern industries focused on performance and environmental responsibility.

Common Industrial Applications

The QUINT PS/1AC/24DC/5/CO is designed to meet the needs of diverse industrial environments. It’s widely used in PLC and remote I/O control panels, safety and communication systems, and machine-building applications that require dependable power. Its protective coating and wide temperature range make it ideal for water treatment plants, chemical processing facilities, and outdoor automation systems. Thanks to its durability, flexibility, and compliance with global standards, this model continues to be a go-to solution for engineers across multiple industries.

Conclusion 

The Phoenix QUINT PS/1AC/24DC/5/CO isn’t just a power supply—it’s a complete reliability solution. With its advanced protection features, energy efficiency, and intelligent diagnostics, it keeps industrial systems running smoothly under any conditions. For businesses seeking superior uptime, safety, and sustainability, choosing this model is a smart move toward long-term operational excellence and dependable power performance.
