STATUS AND CONTROL SIGNALS

V1_SENSE

V1SENSE_RTN

Input

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:

V1_SENSE directly connected to power blades 6 to 10 (inclusive)

V1_SENSE_RTN directly connected to power blades 1 to 5 (inclusive)

Compensation for up to 0.12Vdc total connection drop

(output and return connections).

ISHARE

Bi-Directional

Analogue

Bus

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).
