Product Description

Overview

The QUINT-PS-100-240AC/24DC/2.5 (Part No. 2938578) is a robust DIN-rail mounted DC power supply from Phoenix Contact's QUINT POWER line, delivering reliable 24 V DC output. Designed for high-demand industrial applications, this unit combines precise voltage regulation with advanced monitoring to protect sensitive electronics and controllers. Its compact profile and wide input range make it ideal for installations where space efficiency and dependable operation are critical.

Key Features and Performance

Preventive Function Monitoring: Constantly evaluates output conditions and triggers a floating relay or transistor output when the voltage deviates from normal operation, allowing preemptive maintenance before system shutdown.

Power Boost Capability: Supports up to 3.75 A (1.5× nominal) for short bursts, accommodating high inrush currents from motors, solenoids, or other inductive loads.

Universal Input Compatibility: Operates across 85–264 V AC or 90–350 V DC, making it suitable for global deployments without manual voltage adjustment.

High Efficiency: Typical efficiency exceeds 86%, minimizing heat generation and reducing stress on surrounding components.

Mains Buffering: Provides over 20 ms of holdup time at full load, ensuring continuity during short voltage dips.

Short-Circuit and Idling Proof: Incorporates SFB (Selective Fuse Breaking) technology to safely handle overloads and trigger circuit protection devices.

Thermal and Environmental Range: Reliable operation from −25°C to +70°C, with derating above 60°C, enabling deployment in harsh environments.

Compact Design: Only 32 mm wide, freeing up DIN rail space for additional modules.

Technical Specifications

Applications

Ideal for control cabinets, PLCs, sensors, and other sensitive industrial electronics requiring stable 24 V DC power. It is particularly suited for automation systems where reliability and predictive diagnostics are critical.

FAQ

Q: Can this unit handle high inrush loads?
A: Yes, the Power Boost function delivers up to 1.5× nominal current for short-term load surges.

Q: Is remote monitoring supported?
A: Yes, both a floating relay contact and a DC OK output allow integration with control systems for preventive diagnostics.

Q: How does it compare to QUINT4 series?
A: QUINT4 adds NFC communication and advanced diagnostics. The 2.5 A QUINT-PS model remains a reliable “install-and-forget” solution for smaller panels.
