Abstract

A standalone uninterruptible power supply includes a cabinet and a power supply unit. The cabinet has a frame, rails and carrier plates removably disposed on the rails. The power supply unit installed in the frame includes a control module, a power input module, a power output module and cables. The control module is installed in one carrier plate. The power input module and the power output module are electrically connected with the control module and installed in another carrier plate. The cables are detachably connected with the control module, the input module and the power output module.
