Description
Vertiv™ NetSure™ A50B50 DC Power Retrofit is a power solution comprising one or more frames that allow new-generation NetSure
rectifiers to be installed in the -48V Modular Power Series rectifier shelves that house the older model A50B50 rectifiers. The new
rectifiers can operate with or without the original rectifiers in the same system and the same shelf.
The A50IFRM Intelligent Frame accommodates a Rectifier Module, a Controller Unit, a CAN Interface assembly, and IB2 assembly.
The A50EFRM Expansion Frame accommodates a Rectifier Module and a CAN Interface assembly. One Intelligent Frame is required
per power system. The Controller Unit may contain the standard configuration, or may contain an optional special application
configuration.
For more information on system accessories, see SAG588250400.
