What is the Phoenix Contact QUINT‑PS‑100‑240AC/24DC/40?

The Phoenix Contact QUINT-PS-100-240AC/24DC/40 is a high-performance DIN-rail mounted power supply unit designed for industrial automation and control-system environments. With a 24 V DC output at 40 A, it provides robust and reliable power for demanding applications.

Key characteristics include:

• Input range: 110-240 V AC (and 90 V DC to 350 V DC for DC input).

• Output: 24 V DC, 40 A.

• DIN-rail mounting, dedicated for machine-control panels, switchgear, and automation racks.

• Features such as mains buffering (> 20 ms), high inrush-current capability, preventive monitoring — all contributing to high operational reliability.

• Part of the QUINT POWER family by Phoenix Contact, aimed at maximum functionality and system availability.

Key Features

Here is a detailed breakdown of important features of the QUINT-PS 100-240AC/24DC/40:

Wide Input & Robust Design

• Input voltage: 85 V AC to 264 V AC (typical), and 90 V DC to 350 V DC (for DC input variants).

• Frequency: 45–65 Hz for AC.

• Robust ambient capability: Operating ambient temperature from –25 °C to +70 °C (with derating above +60 °C).

• Protection: Short-circuit proof, idle proof, designed for industrial conditions.

High Output & Power Reserve

• Output: 24 V DC at 40 A nominal.

• Mains buffering: > 20 ms at full load, meaning the supply can ride through dips in input voltage without failing.

• “Power Boost” / static boost capability: Allows for high inrush loads (capacitive loads, motor start etc.). For example, within the QUINT family documentation you’ll see up to 125 % static boost, and dynamic up to 200 % for short periods.

• SFB (Selective Fuse Breaking) Technology: Allows the supply to deliver up to six times the nominal current for a short time (e.g., 12–15 ms) so that standard circuit breakers trip quickly and selectively, enhancing system reliability.

Monitoring & Diagnostics

• Built-in LED indicators: “DC OK” and “BOOST” status indication.

• Signal outputs: Active transistor output (DC OK) and a floating relay contact for remote monitoring of the power supply status. of parallel or series connection for redundancy or power expansion.

Reliability & System-Availability Enhancements

• Part of the QUINT POWER family, which emphasises “maximum functionality” and “system availability”.

• Use of robust components including gas-filled surge arresters, wide input ranges, and high ambient rating.

• Designed for industrial environments where uptime is critical (e.g., process plants, manufacturing lines, marine control panels).

Applications

The QUINT-PS 100-240AC/24DC/40 power supply unit is suitable for a wide range of industrial and marine automation settings where a reliable 24 V DC supply at high current is required. Some typical application areas include:

• Control panels and switchgear for manufacturing machines, where multiple sensors, actuators, PLCs, HMIs (Human-Machine Interfaces) are powered from a common 24 V bus.

• Marine automation & ship-board electrical systems, where stable DC supply is needed under demanding environmental conditions (vibration, wide temperature, electrical noise).

• Process plants (chemical, oil & gas, water treatment) where uptime is essential and power interruptions or voltage dips cannot be tolerated.

• Automation in heavy industries (steel, cement, mining) where large loads with high inrush currents (e.g., motors, solenoids) must be reliably powered.

• Infrastructure installations (transport, utilities) where 24 V DC sub-systems power signalling, sensors, control logic, and require redundancy or buffer capability.

• Redundant supply systems where two or more power supplies are combined to ensure continuous operation in case one fails (parallel or series connection).

By choosing such a robust power supply you ensure fewer downtime events, better control over power quality, and reliable long-term operation of your automation infrastructure.

Why Choose This Power Supply?

Here are the compelling reasons to select the QUINT-PS 100-240AC/24DC/40 for your industrial or marine system:

1. High Current Output (40 A at 24 V) – Ideal for feeding demanding loads in one go, reducing need for multiple smaller supplies and simplifying design.

2. Wide Input Range & Mains Buffering – With capability to buffer mains dips and a wide AC/DC input range you gain robustness against mains disturbances, brown-outs, or unstable inputs.

3. Power Reserve & Inrush Handling – Many industrial loads (motors, solenoids, capacitive banks) create high inrush currents at switch-on. The built-in boost and SFB technologies help handle these without supply failures or nuisance trips.

4. Monitoring & Diagnostics Built-In – Early-warning features (DC OK, BOOST signals) allow condition monitoring, predictive maintenance, less reactive downtime.

5. System Availability Emphasis – The QUINT POWER line is explicitly designed for “maximum functionality” and “system availability” which translates to less downtime, fewer failures, and longer system lifetime.

6. Scalability & Redundancy Options – Ability to connect in series or parallel means you can design for either higher power or redundant backup, giving flexibility for future expansion or fault-tolerant systems.

7. Industrial / Marine Suitability – The rugged design, DIN-rail form factor, 24 V logic compatibility, and global approvals make it well suited to both industrial automation and marine‐application usage.

8. Brand Trust & Support – Being part of the globally recognised Phoenix Contact QUINT series reinforces confidence in quality, support, and lifecycle.

9. Efficiency & Thermal Performance – Higher efficiency reduces waste heat, which is critical in confined control-panel environments or marine enclosures where thermal management is key.

10. Future-proofing – Because of features like expandability, diagnostics, and robust design, you are investing in a supply that can serve current loads and scale for future upgrades.
