DC cooling fans suit servers, power supplies

Sanyo Denki America Inc. introduced a counter-rotating cooling fan measuring 80-by-80mm thick. Available in 12V, S-speed and H-speed models, the San Ace 80CR series DC cooling fans are designed for use in servers, storage systems, communications equipment, power supplies and industrial machinery.

The San Ace 80CR models' high airflow and static pressure are made possible by two axially aligned counter-rotating fans. With newly developed blades and frame which improve overall performance, the result is a maximum airflow of 4.53m³/min and static pressure as high as 520Pa. Power consumption is as low as 43.2W, minimum noise generation of 68dB, and L10 life expectancy is 40,000hrs at 60°C. The cooling fan is RoHS-compliant.

Optional features include tachometer sensor and lock-rotor sensor outputs, as well as PWM control, which permits the fans' rotational speed to be accurately controlled in order to attenuate noise and power consumption.

The product is available now with pricing starting at $40each in small quantities.
