Remote Sense

The cage 12V to 3.3V and 5V converters use remote sensing to regulate out voltage drops in

the system for the +3.3V output. The remote sense output impedance to this DC/DC converter

must be greater than 200 . This is the value of the resistor connecting the remote sense to the

output voltage internal to the DC/DC converter. Remote sense must be able to regulate out of

up to 300mV drop on the +3.3V and 5V outputs. Also, the power supply ground return remote

sense (ReturnS) passes through the PDB and the output harness to regulate out ground drops

for its +12V and 5Vsb output voltages. The power supply uses remote sense (12VRS) to

regulate out drops up to the 240VA protection circuits on the PDB.

+12V Outputs Load Requirements

This section describes the +12V output power requirements from the cage with one or two 650-

W power supplies plugged into the input of the cage. The power distribution board divides up

the 12V power from power supply modules into five separate 240VA limited channels. Channels

1 through 4 supply 12V power directly to the end system. The fifth channel supplies power to

the 3.3V and 5V converters. The 5

Notes:

12V maximum output current is 54 A.

Peak power and current loading shall be supported for a minimum of 12 seconds.

12V5 is the power source for the three DC-DC converters to generate 3.3V, 5V, and -12V.
