The Phoenix Contact QUINT-PS/48DC/48DC/5 DC/DC Converter is a compact and high-efficiency solution for stable 48 V DC power supply in industrial systems. With an input range of 30 to 60 V DC and a regulated 48 V DC / 5 A output, it ensures reliable voltage conversion and long-distance cable compensation. Its integrated Selective Fuse Breaking (SFB) technology can trigger circuit breakers up to six times the nominal current, safeguarding systems against overloads. Preventive function monitoring further increases availability by detecting and signaling abnormal operating states early, helping to avoid costly downtime in critical applications.
Built for durability and uninterrupted operation, the QUINT-PS/48DC/48DC/5 offers a permanent POWER BOOST reserve of 125%, ensuring even demanding loads start reliably. The converter isolates circuits for creating independent power systems while regenerating voltage at the end of long cables, maintaining constant stability. With efficiency exceeding 93% and minimal power loss, it reduces energy consumption and heat generation. Its advanced diagnostic functions, LED indicators, and signaling outputs simplify predictive maintenance and system integration. Encased in a rugged aluminum housing with IP20 protection, it is ideally suited for automation, energy distribution, and mission-critical environments where safe and continuous power is essential.

In large-scale manufacturing facilities, equipment is often positioned far from the primary power supply, which can cause voltage drops and unreliable performance. By installing the QUINT-PS/48DC/48DC/5, stable 48 V output can be restored at the end of extended cable lengths. This not only ensures that sensors, controllers, and actuators receive the correct voltage but also protects against interference from adjacent systems. The built-in electrical isolation provides additional security by separating different supply segments, preventing disturbances from spreading. This makes the converter an ideal choice for distributed automation systems where reliable power delivery is essential across long wiring distances.
Certain industrial devices, such as motor drives, pumps, or servo systems, demand a high surge of current at startup. Without proper support, this can lead to voltage dips, stalled equipment, or tripped protection devices. The QUINT-PS/48DC/48DC/5 solves this by offering a permanent POWER BOOST function, supplying up to 125% of its nominal current. This reserve enables demanding loads to start up safely without overloading the supply. By ensuring smooth power delivery during these critical moments, production can continue without interruptions, protecting both the equipment and the overall process from unnecessary downtime or costly system resets.
Automation systems often involve multiple connected devices, where a single short circuit can risk halting the entire operation. The QUINT-PS/48DC/48DC/5 features Selective Fuse Breaking (SFB) technology, which provides a powerful, brief current pulse to rapidly trip standard circuit breakers. This isolates the faulted section while keeping the rest of the system running, minimizing production disruptions. By allowing unaffected areas to remain active, maintenance teams can address problems without shutting down the entire process. This targeted protection reduces costs, shortens repair times, and significantly improves the overall resilience of automated production environments.
Industrial applications in railways, energy systems, or outdoor installations face extreme temperatures, vibration, and humidity. The QUINT-PS/48DC/48DC/5 is engineered to operate from -25 °C up to +70 °C, with reliable startup even in sub-zero conditions. Its robust aluminum housing and tested durability against shocks and vibrations make it suitable for challenging environments. This ensures continuous power delivery in systems where reliability is non-negotiable, such as signaling in transportation networks or power distribution in energy plants. By maintaining consistent operation under demanding conditions, it supports mission-critical infrastructure that cannot afford unexpected downtime.
