PHOENIX CONTACT QUINT-PS/1AC/24DC/40 — 40A Primary-Switched Industrial Power Supply | QUINT POWER Series
Engineering Background: The QUINT POWER series represents PHOENIX CONTACT’s flagship line of primary-switched power supplies, engineered specifically for demanding industrial environments where reliability, dynamic response, and system uptime are non-negotiable. The QUINT-PS/1AC/24DC/40 delivers 24 VDC at 40 A (960 W) from a single-phase AC input, making it the preferred choice for high-current PLC panels, distributed control systems, and safety-critical automation architectures.
Product Positioning: Designed for procurement engineers and system integrators who require a certified, field-proven power supply with active power boost, SFB (Selective Fuse Breaking) technology, and comprehensive diagnostic output. This unit eliminates the need for external UPS buffering in many applications by supporting capacitive bridging modules and redundancy modules directly on the DIN rail.

Proven Application Environments
- PLC & DCS Control Panels: Primary 24 VDC bus supply for Siemens S7, Allen-Bradley ControlLogix, Schneider Modicon, and Beckhoff CX series controllers.
- Process Automation: Continuous power for field instruments, transmitters, and I/O marshalling cabinets in oil & gas, chemical, and water treatment plants.
- Machine Safety Systems: Powering safety relays, light curtains, and emergency stop circuits where SFB technology ensures selective downstream fuse clearing without nuisance tripping.
- Redundant Power Architectures: Paired with QUINT-DIODE/40 or QUINT-UPS modules for N+1 redundancy and capacitive bridging in mission-critical installations.
- Transportation & Infrastructure: Railway signalling cabinets, tunnel ventilation control, and building automation systems requiring wide-temperature operation.
Engineering Advantages
- SFB Technology (Selective Fuse Breaking): Delivers up to 200% rated current for ≥12 ms to reliably blow downstream branch fuses, eliminating the need for oversized upstream protection and simplifying panel design.
- Active Power Factor Correction (PFC): PF > 0.99 reduces harmonic distortion on the supply network, compliant with EN 61000-3-2 Class A.
- Wide-Range Input: 85–264 VAC universal input supports global deployment without manual voltage selection.
- Diagnostic Signal Contact: Floating relay output provides early warning of output voltage deviation, enabling predictive maintenance integration with SCADA/DCS systems.
- High Efficiency: ≥95.5% efficiency minimises heat dissipation, reducing enclosure cooling requirements and operating costs.
- Compact Footprint: 82.5 mm DIN rail width delivers 960 W in a space-optimised housing, freeing panel real estate for other components.
System Architecture & Signal Flow
The QUINT-PS/1AC/24DC/40 operates as a primary-switched, isolated power supply. AC mains input passes through an EMC filter and bridge rectifier to a high-frequency switching stage (PFC + LLC resonant converter), producing a regulated 24 VDC output. The DC OK relay contact monitors output voltage within a ±15% window and opens on undervoltage or overvoltage, providing a hardwired alarm signal to the PLC digital input or safety relay. The SFB circuit continuously monitors load current and activates the boost mode autonomously — no external configuration required. Output terminals accept up to 16 mm² conductors for high-current bus bar connections.

Technical FAQ
Q: Can the QUINT-PS/1AC/24DC/40 operate in parallel for redundancy?
A: Yes. Use the QUINT-DIODE/40 ORing diode module to connect two units in parallel for N+1 redundancy without load-sharing issues.
Q: What is the derating above 60 °C?
A: Output current must be linearly derated from 40 A at 60 °C to 24 A at 70 °C. Consult the datasheet Figure for the full derating curve.
Q: Is the output voltage adjustable?
A: Yes, via the front-panel potentiometer from 18 VDC to 29.5 VDC. Factory default is 24.0 VDC.
Q: Does this unit support UPS buffering?
A: Yes. Connect the QUINT-BUFFER/24DC/40 capacitive buffer module directly to the output terminals for mains-failure bridging up to several seconds depending on load.
Q: What certifications are required for ATEX Zone 2 installations?
A: The QUINT-PS/1AC/24DC/40 holds ATEX II 3 G certification for Zone 2 hazardous area installation when mounted in a suitable enclosure. Consult the ATEX certificate for full conditions of use.
