1U intelligent fan trays from Verotec

The fan trays are fully compatible with the Diplomat range of 19 desk-top enclosures and are also designed to provide forced cooling up through the active area of a subrack in any standard 19 rack or cabinet. The intelligent units are managed by a programmed controller that restricts the fans at half speed up to 35°C, subsequently linearly increases the speed to maximum at 55°C, ensuring that sound levels and energy consumption are optimised. The intelligent versions are available in either auto-ranging AC or -48V DC input versions.

As packaging densities increase and power usage rises, thermal management is assuming an increasingly important role in many different areas of the electronics industry to ensure reliable operation and long life. The units are designed to provide localised cooling of 19 rack mounted or desktop equipment, and can be used to provide forced draught cooling from below or alternatively to remove hot air from above the heat generating equipment. The efficient units combine high air throughput with low current consumption.
