Proven Application Environments
- Discrete Manufacturing: PLC I/O bus power, servo drive 24 V logic rails, safety relay circuits
- Process & Chemical Plants: DCS field instrument loops, HART transmitter power, solenoid valve panels
- Building Automation & Infrastructure: BMS controllers, access control panels, fire & gas detection systems
- Transportation & Rail: Trackside signalling cabinets, rolling stock auxiliary power (EN 50155 environments)
- Oil & Gas / Hazardous Areas: Zone 2 / Div 2 certified installations with ATEX / IECEx compliance
- Renewable Energy: Wind turbine nacelle control, solar inverter monitoring racks
Engineering Advantages
- SFB Technology (Selective Fuse Breaking): Delivers up to 3× rated current for ≥ 12 ms to reliably blow downstream branch fuses without tripping the upstream breaker — eliminating nuisance shutdowns.
- Active Power Boost: Handles high inrush loads (motors, solenoids) without output voltage collapse, maintaining bus stability during transient events.
- Universal AC Input: 85 – 264 VAC auto-ranging eliminates the need for input voltage selection switches, simplifying global panel standardization.
- High Efficiency ≥ 93 %: Reduces heat dissipation inside enclosures, lowering cooling requirements and extending component life.
- Integrated Diagnostics: Green/red LED status indication and potential-free signalling contact for remote monitoring via PLC or SCADA.
- Compact 45 mm DIN Rail Footprint: Maximizes panel real estate in space-constrained enclosures.
- Long MTBF > 500,000 h: Minimizes unplanned downtime and lifecycle replacement costs.
System Architecture & Signal Flow
The QUINT PS/1AC/24DC/10 operates as a primary-switched (switch-mode) topology:
- AC Input Stage: EMC filter → bridge rectifier → bulk capacitor bank (PFC passive)
- DC-DC Conversion: High-frequency PWM switching (≥ 100 kHz) → transformer isolation → synchronous rectification
- Output Regulation: Closed-loop voltage regulation with ±1 % load/line regulation; adjustable via front-panel potentiometer (18 – 29.5 VDC)
- SFB Boost Circuit: Dedicated current-boost path activates on output short/overload, delivering 3× Inom for selective downstream fuse clearing
- Signalling Output: Potential-free relay contact (24 VDC / 1 A) opens on undervoltage — wired to PLC DI for remote fault annunciation

Technical FAQ
Q: Can this PSU operate in parallel for redundancy?
A: Yes. Two QUINT PS/1AC/24DC/10 units can be paralleled using the Phoenix Contact QUINT-DIODE/40AC/2X20/1X40 redundancy module for 1+1 redundant 24 VDC systems.
Q: What is the difference between QUINT and TRIO power supplies?
A: QUINT features SFB technology and active power boost; TRIO is a cost-optimized line without boost capability. QUINT is recommended for applications with branch circuit protection requirements.
Q: Is derating required above 60 °C?
A: Yes. Output current must be linearly derated from 10 A at 60 °C to 8 A at 70 °C. Consult the Phoenix Contact datasheet (Doc. No. 107547_en_01) for the full derating curve.
Q: What fuse is recommended on the AC input?
A: Phoenix Contact recommends a 6.3 A / 250 VAC slow-blow fuse on the L conductor for single-phase 230 VAC installations.
Q: Can output voltage be adjusted in the field?
A: Yes. The front-panel potentiometer allows adjustment from 18 VDC to 29.5 VDC without tools. Set to 24.0 VDC for standard 24 V bus systems.
