Phoenix Contact QUINT-PS/1AC/24DC/5 – 24VDC 5A Single-Phase DIN Rail Power Supply | QUINT-PS Series
Engineering Background
The QUINT-PS series represents Phoenix Contact’s flagship line of industrial power supplies, engineered for mission-critical automation environments where voltage stability and load response are non-negotiable. Designed and manufactured in Germany, the QUINT-PS/1AC/24DC/5 (Article No. 2866750) delivers 24 VDC at 5 A continuous output from a single-phase AC input, making it the standard choice for compact control cabinets, distributed I/O panels, and PLC power rails across process and factory automation.
Product Positioning
This unit is purpose-built for procurement engineers who require a certified, field-proven power supply with predictable performance under dynamic load conditions. The integrated Static Boost (SFB) technology delivers up to 200% rated current for 12 ms to ensure reliable startup of capacitive and motor loads — eliminating nuisance tripping that plagues standard SMPS units in industrial deployments.

Engineering Advantages
- SFB Technology: 200% peak current for 12 ms ensures reliable startup of inductive and capacitive loads without oversizing the PSU
- Wide Input Range: 85–264 VAC universal input eliminates the need for separate SKUs across global installations
- Active Power Factor Correction (PFC): PF > 0.99 reduces harmonic distortion on facility power infrastructure
- Parallel Operation: Supports redundant N+1 configurations with optional decoupling modules
- Signaling Output: Potential-free relay contact for remote monitoring of DC OK status
- Adjustable Output: 18–29.5 VDC trim range accommodates long cable runs and voltage-drop compensation
- Compact 45 mm Width: Maximizes usable DIN rail space in space-constrained enclosures
System Architecture & Signal Flow
AC mains input → EMC input filter (Class B) → Bridge rectifier & PFC stage → High-frequency PWM converter (LLC topology) → Output rectification & filtering → 24 VDC output bus. The integrated SFB circuit monitors output current in real time; upon detecting a load surge, it temporarily boosts output current to 200% rated value for up to 12 ms before reverting to continuous-rated operation. The DC OK relay (NO contact, 24 VDC / 1 A) closes when output voltage is within ±15% of set point, providing a hardware-level health signal to the PLC or SCADA system.

Technical FAQ
Q: Can this unit operate in parallel for redundancy?
A: Yes. Use Phoenix Contact’s redundancy modules (e.g., QUINT-ORING) to achieve N+1 redundant configurations without load-sharing imbalance.
Q: Is the output voltage adjustable?
A: Yes, via the front-panel potentiometer, output can be trimmed from 18 to 29.5 VDC to compensate for cable voltage drop.
Q: What does the DC OK relay signal?
A: The potential-free NO relay contact closes when output voltage is within ±15% of the set point, providing a hardware health signal to PLC digital inputs or SCADA systems.
Q: Is this unit suitable for ATEX Zone 2 installations?
A: Yes, the QUINT-PS/1AC/24DC/5 carries ATEX and IECEx certification for Zone 2 hazardous area use when installed per the applicable installation guidelines.
Q: What is the warranty?
A: Phoenix Contact standard warranty applies (3 years). Konmask.com provides additional sourcing guarantee — contact us for details.
