The Phoenix Contact QUINT 4 (2904602) is a professional-grade, 1-phase primary-switched power supply engineered for industrial environments where maximum system availability is critical. It is ideal for control systems requiring reliable 24V DC power with advanced diagnostics, featuring Selective Fuse Breaking (SFB) technology to ensure that local faults do not take down an entire network. While its robust design and feature set provide unparalleled control, users should note that the device requires careful configuration via the NFC interface to fully leverage its specialized alarm and monitoring capabilities.

Yes, you can use the Phoenix Contact power supply app available for smartphones or the software suite on a PC equipped with an NFC reader.
Yes, the operating temperature range is -25°C to 70°C, making it suitable for cold-start environments.
SFB allows the power supply to provide a high short-circuit current to trip faulty branch circuit breakers selectively, preventing the entire power line from shutting down.
The QUINT 4 features a wide-range input, allowing for worldwide use across standard industrial grid voltages.
The dynamic boost allows for significantly higher power output for a short duration, specifically designed to handle the high inrush currents of complex loads like motors.
Check input wiring and confirm that the primary power source is within the specified voltage range. Use the diagnostic LEDs to check for fault status codes.
Ensure your smartphone NFC antenna is positioned directly over the unit's NFC symbol. Remove any metallic objects or phone cases that might interfere with the signal.
Verify that your circuit breaker type is compatible with SFB technology requirements. If it continues to trip, inspect the load for actual persistent short circuits.
Installation should be performed on a standard DIN rail. Ensure there is adequate clearance around the unit to allow for heat dissipation, as the power supply is convection-cooled. Wiring should be completed according to the terminal markings for input (L/N/PE) and output (+/-). To configure the unit, use the Phoenix Contact NFC app or the corresponding software suite; the antenna on the front of the unit facilitates wireless communication. For long-term care, ensure the ventilation slots remain free of dust and debris, especially in high-temperature environments. Periodically check that all terminal screws remain tight to prevent high-resistance connections.
