UPS

SANYO DENKI’s Cooling Systems Division has been developing and offering fans chiefly for the purpose of cooling the inside of equipment. Starting with AC fans, we developed brushless DC fans responding to changing market trends, and now we also offer ACDC fans, which are brushless DC fans that can be powered by AC power by internally converting AC power to DC power.
Use of an uninterruptible power supply (hereinafter, “UPS”) had once been limited to special applications but has now become common. Nowadays, for example, UPSs are used in a wide variety of applications such as telecommunications equipment, factory equipment, store equipment, and office equipment, and they are used in many countries. Therefore, UPSs today are required to operate safely even with variations in environmental and power supply conditions.
