Boston Design Solutions will Design a Fan Controller to meet your Specifications:

• System Optimized Controller & Fan Controller designed to meet cooling requirements
• Single or Multiple, Redundant Fan Shelves
• Optically Isolated Control & Status
• On board DC-to-DC converters
• Hot swappable bi-directional buffers
• Redundant, two channel I2C switch for fail free communication with system controller
• Synchronized fan control to reduce audible beat frequency
• Software enabled, automatic fan speed control
• N+1 Fan and 1+1 System Redundancy
• Programmable status LED’s

Typical Specifications

• Redundant -48V nominal input voltage
• On-board DC-to-DC converters to regulate voltage to the fans and control logic.
• Input power filter and in-rush current limit circuit and power pin sequencing to allow hot-insertion
• Optically isolated control and status signals to the system controller, eliminating the possibility of ground loop
• Able to Communicate to a pair of redundant system controllers via a two channel I2C (SMBus) switch
• Hot swappable I2C bi-directional buffer, allowing long backplane traces or cables.
• Control and monitor up to 16 linear fans
• Control and monitor up to 16 PWM (20Hz to 250Hz)
• Supports hot swapping of Fans
• Supports backup and redundant Fans
• Synchronized fan control to reduce audible beat frequency
• Software controlled and automatic fan speed control
• Automatic fan speed control allows control independent of system controller intervention
• Allows N+1 Fan configuration for high reliability
• Provides control signals for 1+1 Fan tray redundancy
• Programmable status signals to control LEDs
