Engineering Background
The QUINT POWER series represents Phoenix Contact’s flagship line of industrial power supplies, engineered for mission-critical automation infrastructure where voltage stability and fault resilience are non-negotiable. Introduced to address the growing demand for intelligent power management in IEC 61131-compliant control cabinets, the QUINT-PS-100-240AC/24DC/10 has become a benchmark reference in PLC panel design across process, manufacturing, and building automation sectors.
Product Positioning
The QUINT-PS-100-240AC/24DC/10 (Order No. 2938604) is a 240 W, single-phase primary-switched power supply delivering a regulated 24 VDC / 10 A output from a universal 100–240 VAC input. Its patented Static Boost (SFB) technology provides up to 200% peak current for reliable downstream device startup and selective fuse tripping — a critical differentiator for engineers designing fault-tolerant 24 VDC distribution buses.

- Adjustable Output Voltage — 18–29.5 VDC trim range compensates for long cable runs and voltage drop in distributed I/O architectures
- DC OK Signaling — Potential-free relay contact enables PLC-level power fault detection and alarm integration without additional monitoring hardware
- High Efficiency ≥93% — Reduces thermal dissipation in sealed enclosures; extends panel component lifespan and reduces cooling requirements
- Parallel Redundancy — Native support for N+1 configurations using Phoenix Contact Powerbridge decoupling modules (no external diodes required)
- Compact DIN-Rail Footprint — 55 mm width minimizes panel real estate; compatible with standard 35 mm DIN rail per EN 60715
System Architecture & Signal Flow
The QUINT-PS-100-240AC/24DC/10 operates as a primary-switched, isolated AC/DC converter. The AC input is rectified and filtered, then processed through a high-frequency PWM switching stage (typically 100–200 kHz). The transformer-isolated secondary is regulated via feedback control to maintain 24 VDC ±1% under all load conditions.
Typical Panel Wiring Architecture:
- L1/N/PE → Input terminals (fused at 6 A MCB, C-curve recommended)
- +24V / 0V → Output bus bar or terminal block distribution
- DC OK relay → PLC digital input (fault monitoring)
- Parallel units → Powerbridge module for redundancy decoupling
Grounding: PE terminal must be connected to protective earth. Output 0V may be grounded or floating per system design. Functional earth (FE) terminal available for EMC shielding.

Technical FAQ
Q: Can two QUINT-PS-100-240AC/24DC/10 units be paralleled for 20 A output?
A: Yes. Use Phoenix Contact Powerbridge (e.g., QUINT-ORING/24DC/2X10/1X20) for lossless current sharing and decoupling. Direct parallel connection without decoupling is not recommended.
Q: Is this unit suitable for ATEX Zone 2 installations?
A: Yes, with appropriate enclosure. The unit holds ATEX II 3 G certification for Zone 2 gas hazardous areas when installed in a certified Ex e or Ex d enclosure.
Q: What MCB rating is recommended for the AC input?
A: Phoenix Contact recommends a 6 A, C-curve MCB. B-curve breakers may nuisance-trip due to inrush current at cold start.
Q: Can the output voltage be adjusted under load?
A: Yes. The output trim potentiometer is accessible from the front panel and can be adjusted from 18 to 29.5 VDC while the unit is energized.
Q: What is the DC OK relay contact rating?
A: The DC OK relay is rated 24 VDC / 1 A (resistive load). It closes when output voltage is within the normal operating window and opens on undervoltage or output fault.
Q: Does Konmask provide a Certificate of Origin for customs clearance?
A: Yes. A COO (Country of Origin: Germany) is included with every shipment. HS Code 850440 applies for import classification in most jurisdictions.
