Allen-Bradley QUINT-PS/1AC/24DC/10 Power Supply Unit

Technical Specifications Breakdown

Key parameters for the QUINT-PS/1AC/24DC/10 are listed below for quick reference:

Industry Applications

In a typical automotive assembly line, the SFB technology ensures that a short circuit on one sensor does not trip the entire control panel. Instead, the faulty branch is isolated quickly, allowing the rest of the line to continue operating. This selective protection minimizes downtime and simplifies troubleshooting, directly improving operational ROI.

Another common use is in process industries where reliable starting of heavy inductive loads is critical. The static power reserve (POWER BOOST) delivers up to 15 A for a short duration, ensuring motors and contactors start reliably even with high inrush currents. This feature prevents nuisance tripping and increases the lifespan of downstream components.

Installation & Setup Guidance

Mount the unit on a standard DIN rail in a well-ventilated enclosure. Maintain the recommended installation clearances: 5 mm horizontally and 50 mm vertically to ensure adequate airflow. Use screw connections with a tightening torque of 0.5 to 0.6 Nm. The unit accepts conductors from 0.2 mm² to 2.5 mm² (AWG 16 to 12). For input protection, install a circuit breaker rated between 10 A and 20 A with characteristics B, C, D, or K. For DC operation, connect a suitable fuse upstream as per the datasheet.

Maintenance & Reliability

The QUINT-PS/1AC/24DC/10 is designed for high reliability, with an MTBF exceeding 940,000 hours at 25 °C. Preventive function monitoring reports critical operating states before errors occur, allowing for planned maintenance. Inspect the unit periodically for dust accumulation and ensure the ambient temperature stays within -25 °C to 70 °C. Above 60 °C, derate the output current by 2.5% per Kelvin. Keep the unit clean and dry to maintain its IP20 rating.

Power Supply Unit for Critical Automation

In modern manufacturing, voltage dips and overloads can halt production lines, causing costly downtime. The Allen-Bradley QUINT-PS/1AC/24DC/10 power supply unit addresses this challenge with its QUINT POWER technology, ensuring reliable 24V DC power for control systems, sensors, and actuators. This unit is engineered for maximum system availability, making it a cornerstone for robust industrial operations.

Compatibility & Integration

The unit provides multiple signaling outputs: a DC OK active signal (high when UOUT > 0.9 x UN), a floating relay contact, and a POWER BOOST active signal. These signals can be integrated into PLC or SCADA systems for remote monitoring. The unit is approved for DeviceNet™ power supply conformance, making it suitable for DeviceNet networks. It also meets SEMI F47-0706 for semiconductor industry voltage dip requirements.

Selection Guide & Purchasing Advice

When selecting a power supply, consider your load profile and required hold-up time. The QUINT-PS/1AC/24DC/10 offers a mains buffering time of >36 ms at 230 V AC, which is critical for ride-through during brief interruptions. For redundancy or increased capacity, the unit can be connected in parallel. Always verify the current lifecycle status and availability with AutoDCSTech before ordering.
