Verotec has extended its range of 19-inch 1U standard fan trays. Two depths are available, a 250 mm deep unit fitted with three fans and a 350 mm deep unit with six fans. All sizes are offered with a choice of 12, 24 or 48 V d.c. fans or 115 or 230 V a.c. fans, and each unit is available with or without a replaceable filter.
Each DC fan is rated at 170 m³/h, the 115V a.c. fans at 180 m³/h and the 230V a.c. fans at 160 m³/h. The fan trays are fully compatible with the Diplomat range of 19-inch desktop enclosures and are also designed to provide forced cooling up through the active area of a subrack in any standard 19-inch rack or cabinet.
The intelligent units are managed by a programmed controller that restricts the fans at half speed up to 35°C, and subsequently linearly increases the speed to maximum at 55°C, ensuring that sound levels and energy consumption are minimised. The intelligent versions are available in either auto-ranging a.c. or 48 V d.c. 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-inch 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.
