Abstract

A rack mounted rectifier has a cooling fan module which is removable and replaceable in the field for servicing the rectifier when a cooling fan failure occurs. The rack mounted rectifier module includes a rectifier unit, a housing, DC output contacts, AC input contacts, and a data signal connector. The cooling fan module has a mounting bracket, a cooling fan unit which is secured to the mounting bracket, and a cooling fan connector which is mounted to the mounted bracket and electrically connected to the cooling fan motor. The housing of the rectifier unit has a socket for receiving the cooling fan module and a mating cooling fan connector for engaging the cooling fan connector to electrically connect the cooling fan unit to electric power when the cooling fan module is fully inserted within the socket. The socket for receiving the cooling fan module is open on a side of the housing of an exterior portion of the rectifier module, and is located for removing the cooling fan module only after the housing which has been partially removed from within the rectifier cabinet. The socket is located in the housing such that the cooling fan module cannot be removed from the housing until the rectifier module is at least partially removed from the enclosed space, such that the DC output contacts and the AC input contacts of the rectifier module are disconnected from mating contacts of the rectifier cabinet.
