1、A-A-50b22 1919974 0363524 09b 1 INCH-POUND 1 A-A-50622 14 March 1994 COMMERCIAL ITEM DESCRIPTION SURGE SUPPRESSOR FOR SHIPBOARD PERSONAL COMPUTERS AND PERIPHERAL EQUIPMENTS The General Services Administration has authorized the use of this Commercial Item Description. Abstract. This Commercial Item
2、Description covers cord-connected surge suppressors with or without individual switches for receptacles. These transient voltage surge suppressors (TVSS) are intended to limit the maximum amplitude of transient voltage surges on shipboard power lines that supply personal computers and other peripher
3、al equipment. These CID requirements cover hybrid surge suppressors: an assembly of series and parallel, or any combination of suppression elements with compatible filter devices to limit voltages, current or both to a specified level. The hybrid TVSS shall include sine wave clamping capability, mul
4、tiple stage surge clamping, and an EMI/RFI noise filtering network. 0 These transient voltage surge suppressors are intended to be installed on the load side of the ships branch overcurrent protection device and operate on an ungrounded delta electrical system. They are not intended to function as s
5、urge arrestors.
