PHOENIX CONTACT QUINT-PS/100-240AC/24DC/10 – Reliable 24 VDC DIN‑rail Power for Demanding Control Panels

This unit is part of the QUINT family known for rock-solid uptime in machine and process automation. Your query showed “QUINT-PS-100-240AC/24DC140,” which typically maps to the single‑phase model written as QUINT-PS/100-240AC/24DC/10 (100–240 VAC in, 24 VDC out, 10 A). From my experience, this 10 A range is the sweet spot for most compact PLC/IPC cabinets, safety relays, and motion I/O islands where stable 24 V power is non‑negotiable.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than 1 month latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Wide‑range input (100–240 VAC, 50/60 Hz): Installs anywhere without tap selection; ideal for global panels.
• 24 VDC, 10 A output (adjustable): Fine‑tune the output for voltage drops on long runs or high‑inrush loads.
• High efficiency, typically up to ~94–95%: Runs cooler, which usually translates into longer service life and smaller enclosures.
• SFB/boost capability: Short bursts of higher current help trip downstream breakers selectively and start heavy loads.
• DC OK relay contact: Simple, reliable monitoring back to the PLC or alarm stack.
• Robust protection: Overload, short‑circuit, and overvoltage protection for stable 24 V buses.
• DIN‑rail (TH35) mounting: Fast install in standard industrial cabinets; tidy wiring and serviceability.
• Parallel/redundant operation (with external modules): For applications where no single PSU can be a point of failure.
• Global approvals: Typically CE and UL/cUL; suitable for most industrial markets.

Technical Specifications

Application Fields

You might notice that this supply fits right into mid‑size control cabinets where clean 24 V power is critical—think machine tools, packaging lines, conveyors, or distributed I/O in process skids. It’s also a strong choice for water/W&WW stations, material handling nodes, and OEM control panels that ship globally and need input flexibility.

• PLC/IPC backplanes, safety relays, and light motion loads
• Panel 24 V bus for sensors, valve manifolds, and HMI backlights
• Redundant 24 V architectures with external decoupling modules
• Retrofits replacing older 24 V supplies with better efficiency

Feedback we hear a lot: “After swapping in a QUINT, nuisance breaker trips basically stopped.” That seems to be the SFB and boost doing their job with brief inrush events.

Advantages & Value

• Reliability under load: Holds 24 V even when downstream loads surge; fewer unexplained PLC resets.
• Compatibility: Works smoothly with common circuit protection schemes and selective coordination.
• Operational savings: Higher efficiency and low heat often allow smaller enclosures and less fan assist.
• Scalable redundancy: Easy to parallel with external redundancy modules for higher availability.
• Supportability: Clear status via DC OK contact makes troubleshooting fast for technicians.

Installation & Maintenance

• Cabinet environment: Mount on TH35 DIN‑rail; allow typical ventilation clearance (top/bottom and sides) to avoid thermal derating.
• Wiring: Use appropriately sized conductors for 10 A DC; tighten terminals to the manufacturer’s torque; ferrules are recommended in many cases.
• Protection: Upstream circuit breaker or fuse sized per local code; keep PE/ground bonding short and low impedance.
• Parallel/Redundancy: For N+1, use external decoupling or redundancy modules to prevent backfeed.
• Routine checks: Periodically verify output setpoint (e.g., 24.0 V), inspect for dust buildup, and confirm DC OK signaling at the PLC.
• Environment: Typically −25…+70 °C operation; consider derating at higher temps and maintain cabinet ventilation.

Quality & Certifications

• Typically CE, UL/cUL Listed; many QUINT variants support industrial and HazLoc categories
• RoHS compliant; manufactured under ISO‑certified quality systems
• Manufacturer warranty practices apply; our commercial warranty: 365 days

If your application needs a different current rating (e.g., 5 A, 20 A, or 3‑phase/40 A), I can match the exact QUINT model and confirm dimensions and approvals before you place the order.
