Phoenix Contact QUINT4 DIN Rail Uninterruptible Power Supply, 18 - 30 V DC Input, 24 V DC Output, 1.44 kW, 51.2 A, 33 2907077

This UPS operates within an input range of 18 to 30 V DC and provides a robust 24 V DC output, supporting a maximum output current of 51.2 A and total rated power output of 1.44 kW. With 33 minutes of backup time, it is ideally suited to protect automation, robotics, and critical industrial control systems from unplanned downtime.

Seamless switch-over capability ensures that the moment a primary power source is interrupted, the UPS promptly delivers backup energy, minimizing the risk of electrical faults or data loss. Its output is continuously monitored for both current and voltage, providing operators with peace of mind that systems remain protected even during unstable power conditions.

The UPS is designed for DIN rail mounting, allowing quick installation within control panels or electrical enclosures. Its housing meets IP20 protection standards, safeguarding internal components from accidental contact and solid objects larger than 12 mm. The flame-retardant casing further increases the device’s resilience and safety profile in demanding environments.

Operational reliability is elevated by the UPS’s intelligent battery management system, which actively monitors battery status and charge for optimal readiness. Integration into modern industrial networks is straightforward, thanks to compatibility with PROFINET, EtherNet/IP, EtherCAT, and USB communication protocols. SFB (Selective Fuse Breaking) technology enables parallel load operation and selective tripping, allowing for uninterrupted performance of connected devices even if faults occur on other loads.

The output is engineered to handle short-circuit scenarios and can function under no-load conditions, which helps protect both the UPS and the equipment powered by it. Compliance with an extensive range of international standards, such as EN 61000-6-4, UL 61010-2-201, and IEC/EN 61850-3, confirms suitability for global deployments and assures reliable operation in the harshest industrial settings.

Designed for key applications in industrial automation, process control, robotics, manufacturing, and critical infrastructure protection, the 2907077 is a prime choice wherever sustained, high-capacity DC power is a necessity. The narrow physical profile (47 mm length, 125 mm width, and 130 mm depth) allows efficient use of enclosure space.

Additional use cases include continuous operation of PLCs, remote communication equipment, sensors, and actuators - anywhere uninterruptible 24 V DC power must be maintained for system stability and data integrity. The included mounting accessories and clear status indicators make for straightforward commissioning in both new installations and system upgrades.
