Uninterruptible power supply
摘要:
An uninterruptible power supply (UPS) (100) has a housing (111) that supports the major electrical components of the UPS (100), i.e., a transformer circuit (207), a switching circuit (217), and a battery (209). Furthermore, a connector (107;115;117) affixed to the housing (111 ) is capable of removably affixing the UPS (100) to an alternating-current (AC) outlet (102).
