Glossary Of Terms


A term used to designate that a connected electrical load is powered up and operating. In the case of a UPS, an on line device powers the load from batteries at all times, and the batteries are continuously charged by the line. When incoming power disappears there is no switching since the batteries are already powering the load. (see: Off Line; Incoming Power; Load; UPS.)
