GB/T 19520.20-2023 Mechanical structures for electrical and electronic equipment—Dimensions of mechanical structures of the 482.6 mm (19 in) series—Part 3-108:Dimensions of R-type subracks and plug-in units
Abstract
This document specifies the dimensions and characteristics of R-type plug-in boxes and plug-ins. R-type plug-in boxes and plug-ins, which are reinforced versions of the 482.6 mm (19 in) series mechanical structure, feature enhanced vibration and impact resistance and/or improved electromagnetic compatibility (EMC) performance for use in more severe environments. This results in a plug-in box standard that is externally compatible with IEC 602973100, but internally largely incompatible with IEC 602973101. Compared with IEC 602973101 (with test configurations and load specifications selected from IEC 615871 and IEC 615875), the dimensions and characteristics covered by R-type plug-in boxes, integrated chassis, and plug-ins reflect a higher level of reinforcement.
