in equipment such as communication devices and power conditioners for photovoltaic power generation which are used for long periods such as 10, 20 years, prolonged maintenancefree operation is ideal and it is desirable that the embedded fans are long-life. moreover, in order to cool the equipment which continue to increase in heat generation year after year, further improved airflow is required. in light of these changing needs, sanyo denki has commercialized a san ace 9lg type in 60 mm sq. x 25 mm thick, 80 mm sq. x 25 mm thick and 92 mm sq. x 25 mm thick. these models are significantly higher airflow than the conventional long-life fans with approximately 20 years life. furthermore, in the counter rotating fan, a san ace 9crl type (60 mm sq. x 76 mm thick, 80 mm sq. x 80 mm thick), with 130,000 hours life, has been commercialized. these are brushing-up models based on long-life technologies we have accumulated since we firstly commercialized in 1991.
while dc fans have been developed for power reduction and long-life, ac fans haven’t been developed them due to difficulty in improvement of the motor efficiency. meanwhile, sanyo denki succeeded in developing an ac fan which consumes power only around one-quarter of conventional models while expected life is extended by approximately 2.4 times. by embedding a circuit inside the fan which converts ac power to dc power, it has become possible to drive a high efficient dc motor. sanyo denki has succeeded in developing ac fans which cover a wide input voltage range (100 v to 240 v ac) in order to respond to power supplies in countries around the world, and also offer approximutely 6 years life. these ac fans feature all the merits of a dc fan.
we introduce the fans were launched in 2013 below. these are products reflected our technologies and achieved industry leading performance. sanyo denki will continue to pursue higher performance fans and improve reliability as well as the development of technologies which contribute to conserving the global environment.read more at this
