Orion Fans: Three-Position Short Fan Tray
An ac three-position short fan tray is now available with an energy-efficient smart thermal control. Designated the OA300ST Series, the smart thermal controller independently increases or decreases the speed of the three fans in response to the ambient air temperature, reducing power consumption by up to 30 percent, said the company. The fan trays can be installed in any standard 19-inch rack, making it ideal for a variety of applications including industrial control cabinets and network system enclosures, said the company. The fan tray is also offered in a model with the thermistor control on a remote lead wire that allows the sensor to be placed close to a specific heat source for more accurate temperature control as well. The series features three high-performance, sealed ball-bearing fans that combine high airflows of up to 320 cfm with low-noise operation as quiet as 23.1dB. Available in 115- and 230-vac versions, the OA300ST Series ac fan tray consists of a ball-bearing system, 2M-length power cord, a lighted rocker switch, and a resettable circuit breaker. Rated power for the standard high-speed model is 45W.
