Embedded

•In these shelf-specific applications (Table 4) the rectifiers are designed to fit signals that are brought out from the shelf through an open ended cable or as suited by the particular application requirements.

•the AC input is either common bussed or individually fed, equipped or not, for EMI filtering to the rectifiers.

In all of the above versions the DC output is common bussed within the shelf with separate BAT RTN (+V DC), BAT (-V DC) and LOAD (-V DC) where an LVD is installed.
