Bus voltage reduces with the QTY
of bus connected power supplies
Rapid_ON signal/bus provides these three functions:
Pull-up bus voltage: Bus pull-up is provided by the single PSU or the first PSU assigned the roll of “ACTIVE & MASTER” aka
“COLD_REDUNDANT ACTIVE”. More than one PSU can be assigned as “ACTIVE” only the first PSU assigned this roll provides
the pull-up path and is why this PSU is referred to as the “Master”.
Each bus connected PSU drives the Rapid_ON bus low when any fault is detected.
Each bus connected PSU powers on its main output rapidly within 100µS after detection of LOW state.
Note: “Rapid_ON” pin configuration is retained once setup via PMBus

default setting until commanded to INPUT_OK via PMBus

No additional internal capacitance is added that would affect the speed of the bus.
The signal is provided with a series isolator device to disconnect the internal power supply bus in the event that the power
module is unpowered.
Remote sense connections intended to be connected at and sense the voltage at the point of load.
The voltage sense will interact with the internal module regulation loop to compensate for voltage drops due to connection
resistance between the output connector and the load.
If remote sense compensation is not required then the voltage can be configured for local sense by:
1.
V1_SENSE directly connected to power blades 4 to 6 (inclusive)
2.
V1_SENSE_RTN directly connected to power blades 1 to 3 (inclusive)
The current sharing signal is connected between sharing units (forming an ISHARE bus). It is an input and/or an output (bi-
directional analog bus) as the voltage on the line controls the current share between sharing units. A power supply will respond
to a change in this voltage but a power supply can also change the voltage depending on the load drawn from it. On a single
unit the voltage on the pin (and the common ISHARE bus would read 8VDC at 100% load (module capability). For two identical
units sharing the same 100% load this would read 4VDC for perfect current sharing (i.e. 50% module load capability per unit).
