The QUINT-PS-100-240AC/24DC/40 is a high-performance, single-phase primary-switched power supply unit designed by Phoenix Contact to meet the rigorous demands of modern industrial automation. As a core component of the renowned QUINT POWER series, the QUINT-PS-100-240AC/24DC/40 serves as a reliable bridge between the main AC voltage supply and sensitive 24 V DC loads. It is engineered to deliver a continuous output current of 40 A (960 W) with exceptional stability, making it an ideal choice for powering complex control systems, actuators, and sensors within a control cabinet. Its robust metal housing and advanced thermal management system ensure longevity even in environments with high ambient temperatures or significant electrical noise.At the heart of this device lies intelligent technology that goes beyond simple voltage conversion. The QUINT-PS-100-240AC/24DC/40 features integrated SFB (Selective Fuse Breaking) technology and a static POWER BOOST reserve. These features allow the unit to actively support the selective tripping of miniature circuit breakers, ensuring that a fault in one branch does not lead to a total system shutdown. By monitoring critical operating states and providing real-time feedback via DC OK signaling, the QUINT-PS-100-240AC/24DC/40 transforms passive power distribution into an active element of system availability, significantly reducing downtime and maintenance costs.

Main Features and Advantages
Maximizing System Availability with SFB Technology:
One of the standout capabilities of the QUINT-PS-100-240AC/24DC/40 is its SFB (Selective Fuse Breaking) technology. Standard power supplies often struggle to trip magnetic circuit breakers quickly because their current limiters react too slowly. In contrast, the QUINT-PS-100-240AC/24DC/40 can provide a dynamic current reserve of up to 6 times the nominal current for 12 milliseconds. This ensures that standard miniature circuit breakers trip magnetically and selectively in the event of a short circuit, isolating only the faulty feeder while the rest of the system continues to run without interruption.Reliable Starting of Heavy Loads:
Industrial applications often involve capacitive loads, such as motor starters or large capacitor banks, which require high inrush currents to activate. The QUINT-PS-100-240AC/24DC/40 addresses this with its static POWER BOOST function. This feature allows the power supply to deliver up to 1.5 times the nominal current (60 A) continuously within a specific temperature range. This headroom guarantees that heavy loads start reliably without causing the supply voltage to dip, which could otherwise reset connected PLCs or relays.Preventive Function Monitoring:
Downtime is costly, and the QUINT-PS-100-240AC/24DC/40 is designed to help you avoid it through preventive function monitoring. The unit constantly checks for critical operating states—such as overload, overtemperature, or input voltage fluctuations—and reports them before they escalate into failures. The “DC OK” relay contact allows for easy integration into the control system, enabling operators to receive early warnings and take corrective action before a complete power loss occurs.Robust Design and Global Compatibility:
Built for global use, the QUINT-PS-100-240AC/24DC/40 features a wide-range input that accepts both AC (100-240 V) and DC (120-300 V) voltages. Its metal housing acts as an effective heat sink, dissipating heat efficiently to maintain performance in ambient temperatures ranging from -25°C to +70°C. Furthermore, the unit complies with international standards and holds approvals like UL, cUL, and DNV GL, making it suitable for marine applications and hazardous locations when specified.
Application Field
The QUINT-PS-100-240AC/24DC/40 is extensively used in factory automation and process engineering where reliability is paramount. In automotive manufacturing plants, for instance, robotic welding cells rely on consistent 24 V power for their control logic and solenoid valves; the QUINT-PS-100-240AC/24DC/40 ensures these systems remain operational even during brief grid fluctuations or high-demand startup phases. Its ability to handle harsh electrical environments makes it perfect for driving servo drives and frequency inverters.In the oil and gas industry, particularly in offshore platforms or refineries, equipment must withstand corrosive atmospheres and vibration. The QUINT-PS-100-240AC/24DC/40, especially variants with conformal coating, is deployed to power safety instrumented systems (SIS) and emergency shutdown (ESD) panels. Here, the device’s high Mean Time Between Failures (MTBF) and redundant capability (when paired with a diode module) are critical for maintaining safety integrity levels (SIL). Additionally, in water treatment facilities, the power supply manages the varying loads of pumps and filtration systems, utilizing its efficiency to reduce overall energy consumption.

Installation and Maintenance
Pre-installation preparation: Before installing the QUINT-PS-100-240AC/24DC/40, ensure that the DIN rail (NS 35) is securely mounted and provides adequate ventilation space, particularly above and below the unit to facilitate natural convection cooling. Verify that the input voltage matches the specifications (100-240 V AC) and that the power is disconnected. Use appropriate wire gauges capable of handling the 40 A output current to prevent overheating. It is also crucial to check the local regulations regarding grounding; the PE connection must be solid to ensure EMC compliance and safety.Maintenance suggestions: Routine maintenance of the QUINT-PS-100-240AC/24DC/40 involves periodic visual inspections and electrical checks. Every six to twelve months, inspect the terminal blocks to ensure connections remain tight, as thermal cycling can cause slight loosening over time. Monitor the status LEDs on the front panel; a flashing “DC OK” light may indicate an overload or overtemperature condition. If the unit is installed in a dusty environment, clean the air intake and housing vents to prevent dust buildup which can act as an insulator and trap heat. Always replace the unit with an identical model to maintain system compatibility and protection settings.
