Model Number P0972QM-0C Product Line Foxboro I/A Series Component Type Redundant, Hot-Swappable Fan Assembly / Cooling Module Key Function Provides forced-air cooling for high-density power supply modules in a PSS rack. Electrical Specifications Input Voltage Powered by the power supply rack's internal DC bus, typically +24 VDC or +48 VDC. Fan Speed May operate at a fixed speed or have speed control based on temperature. Physical & Performance Airflow Designed to deliver a specific Cubic Feet per Minute (CFM) or cubic meters per hour (m³/h) to meet the cooling requirements of the associated power supplies. Mounting Slides into a dedicated slot within the power supply chassis, aligned with the cooling vents of the PSUs. Hot-Swappable Yes. Designed to be replaced without powering down the entire power system, ensuring continuous cooling. Redundancy Often used in a redundant (N+1) configuration. If one fan fails, the remaining fans can provide sufficient cooling. Status Monitoring Includes a sensor (e.g., a tachometer signal or Hall-effect sensor) to monitor fan speed and detect failures. Connector Uses a specific electrical connector to interface with the rack's backplane for power and status signaling. Environmental Acoustic Noise Specified to operate below a certain dB(A) level for acceptable noise in the control room environment.
