Default Vout, voltage programmability: A voltage level, Vprog referenced to Logic_GRD, configures the default output voltage
setting of the power supply. The graph/schematic below shows the relationship between Vprog and output voltage, and the
internally set configuration via the resistor divider, setting the output of the power supplies to 48Vdc, (Vprog = 0.587Vdc). The
Vprog signal pins of the two rectifiers are paralleled in the shelf. The Vprog pin is accessible via the J1 connector so the default
output voltage setting can be changed by the user. Note that this hardware configured default/adjust setting is valid only as long
as the output of the rectifiers were not changed via an I
2
C command. Firmware commands over-ride the hardware based Vprog
level. An AC voltage interruption that is long enough to decay the internal V
CC
supplied to the DSP controlling the dc-dc converter
of the rectifier, resets Vout to its hardware (Vprog) set default level. The rectifier will respond to the Vprog set output voltage
instructions until a firmware based output voltage adjustment is received.
8V_INT: This signal pin is interconnected between the two rectifier slots. It is also available on the J2 shelf-to-shelf connector for
reverse bias capability among shelves. The reference for this signal is Vout(-).
Ishare: This signal pin is interconnected between the two rectifier slots. It is also available on the J2 shelf-to-shelf connector for
paralleling capability of rectifiers among shelves. The reference for this signal is Vout(-).
Rectifier Installation
Caution: The rectifier latch is not a carrying handle
To release the latch press the dark gray area
Slide in the rectifier while the latch is in the open position
As resistance is felt when inserting, slowly close the latch to
complete the insertion. When the latch is locked the rectifier is
positively engaged in its housing.
The rectifier can get extracted or inserted while the bus is hot.
The rectifier is keyed to ensure that it gets inserted into the
correct shelf. Do not force mating beyond normally anticipated
resistance in order to avoid permanent damage.
