Curtiss-Wright rolls Hybricon rugged fan controllers

Curtiss-Wright Controls Electronic Systems has introduced a family of Hybricon rugged intelligent fan controllers for chassis management.

The MIL-STD-461F, MIL-STD-810G and MIL-STD-704F fan controllers are intelligent nodes in a PMBus chassis management system. They can be used to monitor and control system fans and report fault conditions in rugged air-cooled or conduction-cooled applications.

Curtiss-Wright proposes two rugged fan controller versions: one provides fan Pulse Width Modulation (PWM) control and the other provides fan voltage regulated control.

The rugged fan controllers can be used as part of a PMBus chassis management system to monitor and control various chassis level elements, such as power supplies, fans, displays, front panel controls and indicators. The chassis management system is modular and extensible.

Main features:
. Rugged extended temperature fan controller family supports both PWM fans and voltage regulated fans (-40° C to 85° C) in both air-cooled and conduction-cooled applications
. Supports 12 VDC, 24 VDC, 28 VDC and (special order) 48 VDC fans
. Voltage regulated version can control 12 VDC or 24 VDC fans directly with MIL-STD-704F 28 VDC input power, eliminating the need for a power supply to regulate the fan voltage
. Support PMBus commands for fan control
. Designed to meet rugged standards including MIL-STD-461F, MIL-STD-810G and MIL-STD-704F

Availability:
The rugged fan controllers are available in Hybricon engineered packaging solutions.
