Product Information
Full details
The Phoenix Contact QUINT-PS/3AC/24DC/5 is a robust 120W DC power supply designed for industrial applications requiring high system availability and reliable power delivery. It is ideal for professionals in automation, control systems, and manufacturing who need consistent power for critical equipment, even under heavy loads or during voltage fluctuations. A key benefit is its SFB technology for fast triggering of standard output switches, ensuring operational continuity. However, its wide input voltage range may require careful consideration in regions with highly unstable power grids.

FAQs
What is the primary advantage of SFB technology?
SFB technology ensures reliable triggering of standard output switches, allowing faulty circuits to be disconnected quickly while maintaining power to other parts of the system, thus increasing overall system availability.
Can this power supply be used to charge batteries?
Yes, the unit offers adjustable output voltage, making it suitable for battery charging applications. The specific charging parameters would need to be set accordingly.
How do I increase the total power output?
The total power output can be increased by connecting multiple units in parallel using an appropriate switch bar, which provides both increased capacity and redundancy.
What is the expected lifespan of this power supply?
The power supply boasts a high Mean Time Between Failures (MTBF) of 1,290,000 hours, indicating excellent long-term reliability under specified operating conditions.
What operating temperature range is supported?
The unit can operate reliably within an ambient temperature range of -25°C to 70°C.
Is this power supply suitable for use in different countries?
Yes, it features a wide-range input voltage (320-575V AC) and includes an international approval package, making it suitable for worldwide use.
How long can the unit buffer power during mains failure?
The power supply offers long mains buffering times, exceeding 20ms, ensuring uninterrupted operation during short power interruptions.
Troubleshooting
Unit not powering on
Verify AC input voltage is within the 320-575V range and correctly wired to the input terminals. Check if the circuit breaker supplying power is tripped.
Output voltage is unstable or low
Check the load connections and ensure they do not exceed the unit's power or current limits. Verify the input voltage stability. If using for battery charging, ensure the output voltage is correctly adjusted.
SFB technology not triggering correctly
Confirm that the downstream protective devices (fuses/breakers) are of the standard type compatible with SFB. Ensure the load fault is significant enough to warrant SFB activation.
Preventive function monitoring LED is lit
Consult the unit's manual for specific LED indicator meanings. This typically signals a critical operating condition, such as overload or over-temperature, requiring investigation of the load or operating environment.
Pros and Cons
Pros
- High system availability due to SFB technology.
- Predictive fault detection with preventive function monitoring.
- Reliable power delivery with Power Boost for heavy loads.
- Extended operational safety with long mains buffering (> 20 ms).
- Flexible configuration options for battery charging and parallel operation.
- Suitable for global use with wide-range input and international certifications.
Cons
- Requires careful input voltage consideration in unstable power grids.
- SFB technology may be overkill for basic, non-critical applications.
- No user-serviceable parts inside; requires professional installation.
- Higher initial cost compared to standard power supplies.
Setup, Compatibility & Care
Setup: The unit is designed for DIN rail mounting. Ensure it is installed in a well-ventilated area, adhering to the specified clearances for heat dissipation. Connect the AC input voltage (320-575V AC) to the designated screw terminals. The DC output is also connected via screw terminals, with a maximum wire gauge of AWG 12 (2.5 mm²) supported. For systems requiring redundancy or higher output current, parallel operation can be achieved using the appropriate switch bars.
Compatibility: This power supply is compatible with standard industrial control systems and automation equipment. It operates effectively with 3-phase AC input voltages within the 320-575V range. Ensure that the connected loads do not exceed the 120W total power output or the 7.5A maximum output current.
Care: Regular visual inspection for dust accumulation is recommended. Clean the unit with a dry or slightly damp cloth; avoid using solvents or abrasive cleaners. Ensure ventilation slots remain clear of obstructions. No user-serviceable parts are inside; maintenance should only be performed by qualified personnel.
