The ABB BaileyIEFAN01is a high-reliability Fan Assembly designed specifically for the Infi 90 and Symphony Plus Harmony rack systems. It is an essential thermal management component, providing forced-air cooling to prevent the overheating of critical processor modules (like the IMMFP03) and I/O slave modules housed within the Cabinet Mounting Unit (MMU).
Specifications
Part Number:IEFAN01 (Alternate:P-IEFAN-01,YIEFAN01)
Configuration:Dual-fan unit for redundant or high-volume airflow.
Input Voltage:24 VDC (Standard for Infi 90 power systems).
Current Draw:Approximately 0.5 A to 0.8 A (depending on fan speed and model revision).
Airflow Capacity:High-CFM (Cubic Feet per Minute) output designed to pull heat away from high-density electronic components.
Dimensions:Fits standard 19-inch rack width; height is approximately 1U (1.75 inches).
Weight:~1.2 kg (2.6 lbs).
Operating Temperature:0°C to 70°C (32°F to 158°F).
Features
Redundant Cooling:Typically contains two independent DC brushless fans.If one fan fails,the second continues to provide airflow,reducing the risk of a system-wide thermal shutdown.
Integrated Monitoring:Includes a "Fan Fail" alarm circuit that interfaces with the system's power entry module or a digital input,allowing the DCS to alert operators to a mechanical failure.
Low Noise Design:Balanced fan blades and vibration-dampening mounts minimize acoustic noise and mechanical resonance within the control cabinet.
Easy Maintenance:Designed as a slide-out or front-access assembly,allowing for rapid replacement or cleaning of dust filters without de-energizing the entire rack.
Longevity:Equipped with high-grade ball bearings rated for continuous 24/7 operation in industrial environments.
