1U 19" standard, filtered and intelligent fan trays
Verotec has extended its range of 19" 1U standard fan trays. Two depths are available, a
250mm deep unit fitted with three fans and a 350mm deep unit with six fans. All sizes are offered with a choice of 12, 24 or 48 VDC fans or 115 or 230 VAC fans, and each unit is available with or without a replaceable filter. Each DC fan is rated at 170 m3/h, the 115 VAC fans at 180 m3/h and the 230VAC fans at 160 m3/h. 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.
