Phoenix QUINT-PS/3AC/24DC/20 Switched-Mode Power Supply

Product Dimensions：

The Phoenix Contact QUINT-PS/3AC/24DC/20 is a high-end, industrial-grade power supply from the QUINT POWER family. It is designed for maximum system availability and is widely regarded as the gold standard for demanding automation and process control applications.

Product Detailed Description

The QUINT-PS/3AC/24DC/20 is a primary-switched power supply that converts a three-phase AC input into a stabilized 24 V DC output. Its standout feature is the SFB (Selective Fuse Breaking) Technology, which provides a surge of current to trip standard circuit breakers quickly, ensuring that faulty paths are isolated while the rest of the system remains powered.

Technical Parameters

Product Advantages

• SFB Technology: Delivers 6 times the nominal current for 12 milliseconds. This allows standard power circuit breakers to trip magnetically, preventing a single fault from shutting down the entire 24V bus.
• Preventive Function Monitoring: Comprehensive diagnostics via a DC OK signaling output and floating relay contact. It warns the system before a failure occurs by monitoring the output voltage and current.
• Static Power Boost: Provides up to 125% of the nominal current continuously at lower ambient temperatures, allowing for reliable starting of heavy loads without oversizing the power supply.
• High Noise Immunity: Features integrated gas-filled surge arresters and high electromagnetic compatibility (EMC), making it suitable for electrically “noisy” environments near large motor drives.
• Adjustable Output: The output voltage can be compensated for long cable runs via the front-facing potentiometer.

Important Considerations (Precautions)

• Phase Connection: This is a 3-phase unit. While it can often operate on two phases in an emergency, the output power will be derated, and the internal components will experience higher stress.
• Heat Dissipation: Ensure a minimum clearance of 50 mm above and below the unit and 5 mm on the sides to ensure proper convection cooling.
• Secondary Side Protection: When using SFB technology, ensure the cable cross-sections to the loads are sized correctly to handle the 120A peak pulse without excessive voltage drop.
• Grounding: The PE (Protective Earth) terminal must be connected to a low-impedance ground to ensure safety and effective EMI filtering.

Product Applications

The QUINT-PS/20A is typically found in mission-critical infrastructure:

• Automotive Manufacturing: Powering PLC racks, HMI panels, and industrial robots where downtime costs thousands of dollars per minute.
• Oil & Gas: Reliable power for control systems in offshore platforms and refineries.
• Power Plants: Control and monitoring systems that require high immunity to electrical interference.
• Machine Building: High-performance machines requiring significant inrush currents for DC motors or large solenoid banks.
