Custom Fan Tray Design

Custom Fan Tray Design – Fan Tray for Telecom Cooling

Control Resources’ custom electronic design and manufacturing group provided a dual telecom fan controller solution for this unique fan tray design. These custom fan controllers include three 3A power regulators for redundancy in each bank of 3 fans. A “master / slave” relationship between the two controllers exists for I2C communications to the backplane and for the initial power feed. Our experience with telecom fan controller design optimized this fan tray for maximum performance and reliability. CRI’s ISO 9001:2000 registered electronic design and manufacturing facilities have the capability to provide complete custom fan tray solutions from prototype to production.
