Premium Industrial Power: Phoenix Contact QUINT4-PS/1AC/24DC/20 High-Performance Power Supply
In high-demand industrial automation, a power failure can halt an entire production line, leading to catastrophic losses. For global procurement managers, system integrators, and electrical engineers who require zero down-time and maximum system availability, the Phoenix Contact QUINT4-PS/1AC/24DC/20 is the definitive industry-standard solution.
As the flagship 20A model from Phoenix Contact’s premium QUINT POWER range, this single-phase DIN rail power supply is engineered with cutting-edge preventive diagnostics and unparalleled power reserves to handle the most demanding industrial loads.

Why Global Buyers Choose QUINT4-PS/1AC/24DC/20
1. SFB (Selective Fuse Breaking) Technology
Traditional power supplies shut down completely during a localized short circuit, dropping power to the entire PLC cabinet. The QUINT4 features SFB Technology, which delivers up to 6 times the nominal current for 15 milliseconds. This massive energy surge trips standard circuit breakers selectively. Only the faulty path is isolated, while all other critical system components continue running without interruption.
2. Dynamic and Static Power Boosts
Starting heavy inductive loads like DC motors, actuators, or capacitive banks requires intense startup current. The QUINT4 handles this seamlessly with its dual power reserves:
  • Static Boost: Permanently supplies up to 125% (25 A) of the nominal load at ambient temperatures up to 40°C.
  • Dynamic Boost: Supplies up to 150% (30 A) for up to 5 seconds to easily start heavy machinery loads.
3. NFC Technology & Real-Time Diagnostics
The integrated NFC (Near Field Communication) interface allows you to configure precise output parameters, signaling thresholds, and characteristic curves directly via a smartphone or PC app. Furthermore, continuous preventive monitoring tracks output voltage and current in real time, alerting your PLC before a critical system fault occurs.
