Key Features & Benefits

1. Superior System Availability with SFB Technology

• Selective Fault Isolation: Delivers up to 6 times the nominal current (215 A) for 12 ms, enabling fast and reliable tripping of standard circuit breakers. Faulty current paths are switched off selectively, ensuring important system components remain operational.
• Preventive Monitoring: Constantly tracks output voltage and current, visualizes critical operating modes, and sends alerts to the control unit before errors occur—minimizing downtime.
• POWER BOOST for Heavy Loads: Provides a temporary power reserve (45 A at -25°C to 40°C, 24 V DC) to reliably start high-inrush-current loads without voltage dips.
• Long Mains Buffering: Maintains power for >25 ms (400 V AC) or >35 ms (500 V AC) during mains interruptions, preventing data loss or system shutdowns.
• High MTBF: Over 500,000 hours (at 40°C) and 880,000 hours (at 25°C) mean exceptional long-term reliability, reducing maintenance costs.

2. Worldwide Compatibility

• Wide Input Voltage Range: Supports 3-phase AC (320 V AC - 575 V AC), 2-phase AC (360 V AC - 575 V AC), and DC (450 V DC - 800 V AC), adapting to global power grids.
• AC Frequency Flexibility: Operates at 45 Hz - 65 Hz, compatible with most industrial power systems.
• Hazardous Location Approval: Certified for Class I, Division 2, Groups A, B, C, D (ANSI-ISA 12.12), suitable for risky environments like oil, gas, or chemical plants.

3. Flexible Installation & Use

• Adjustable Output Voltage: 18 V DC - 29.5 V DC (constant capacity restricted above 24 V DC) to match diverse load requirements.
• Multiple Mounting Positions:
• Normal position (depth: 176 mm + DIN rail)
• 90° rotated position (depth: 99 mm + DIN rail) for space-constrained cabinets.
• DIN Rail Compatibility: Snaps onto all EN 60715-compliant DIN rails; optional accessories (e.g., UTA 107 universal adapter) simplify installation.
• Parallel/Series Operation:
• Parallel: Increase power (n × 40 A) or enable redundancy (1+1 configuration) for fault tolerance.

• Series: Connect two units to double output voltage (up to 48 V DC).

Installation & Safety Guidelines

Installation Notes

1. Convection Requirements: Maintain a minimum vertical clearance of 50 mm (for heat dissipation) and lateral clearances of 5 mm (passive components) / 15 mm (active components).
2. Wiring:
• Use copper cables rated for >75°C (ambient <55°C) or >90°C (ambient <75°C) to comply with UL standards.
• For DC applications, install a upstream fuse; connect only one power supply per fuse/switch.
3. Phase Redundancy: When connected to 3-phase AC, the unit operates at full capacity even if one phase fails.

Safety Warnings

• Explosion Hazard: Do not remove the unit in potentially explosive areas unless disconnected from power.
• High Voltage Risk: Internal components carry dangerous voltages—never work on live parts.
• Thermal Caution: The housing may become hot during operation; avoid contact and ensure proper ventilation.
• Qualified Personnel: Only trained technicians should install, wire, or maintain the unit, adhering to EN 60950 and local electrical codes.

Monitoring & Signaling

The QUINT-PS/3AC/24DC/40 provides real-time status monitoring via LEDs and signal outputs, enabling proactive system management:

• Active Signal Outputs: Transmit status to controllers (18-24 V DC, ≤20 mA, short-circuit resistant).
• Floating Relay Contact: Switches 30 V AC/0.5 A or 24 V DC/1 A, ideal for PLC digital inputs.
• Signal Looping: Connect multiple units to a single PLC input for group error alerts, reducing wiring costs.

Applications

The QUINT-PS/3AC/24DC/40 3BHE031065R0001 is engineered for industrial environments where reliability and uptime are critical, including:

• Manufacturing: Automated production lines, robotics, and CNC machines.
• Energy: Renewable energy systems (solar/wind), power distribution, and grid monitoring.
• Transportation: Railway signaling, shipboard electronics (DNV GL-approved), and electric vehicle charging infrastructure.
• Process Industry: Chemical, oil, and gas plants (hazardous location-certified).
• Data Centers: Server racks, UPS backup systems, and network equipment.
