QUINT-PS/3AC/24DC/20 Power module

Core Technical Specifications

• Input Voltage: 3-phase AC \(320\text{ V AC} \dots 575\text{ V AC}\) (or \(450\text{ V DC} \dots 800\text{ V DC}\)).
• Output Voltage: \(24\text{ V DC}\) (Adjustable from \(18\text{ V DC} \dots 29.5\text{ V DC}\) via front potentiometer).
• Nominal Output Current: \(20\text{ A}\) continuous (delivering up to 480 Watts of power).
• Power Boost Capacity: Permanent static reserve up to \(26\text{ A}\) at lower ambient temperatures (\(-25^\circ\text{C} \dots 40^\circ\text{C}\)).
• Efficiency: \(> 93\%\) peak efficiency at \(400\text{ V AC}\) nominal input.
• Dimensions: Width \(69\text{ mm}\) x Height \(130\text{ mm}\) x Depth \(122\text{ mm}\).
• Enclosure Rating: IP20 rugged metal housing optimized for horizontal DIN rail mounting. 

Key Performance Technologies

• SFB Technology (Selective Fuse Breaking): Supplying up to 6 times the nominal current (\(120\text{ A}\)) for a brief \(12\text{ ms}\) window, this module can instantly snap open standard secondary circuit breakers. Faulty current loops isolate immediately while critical system infrastructure keeps running smoothly. [1, 2, 3, 4, 5]
• Preventive Function Monitoring: Continuous diagnostic circuits monitor real-time output voltage and current thresholds. Critical states trigger early warning LED alarms and active switching outputs before complete plant faults occur. 
• Phase Failure Resilience: The internal layout ensures flawless power output delivery even during permanent failure of one input electrical phase
