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). Analogue voltage: +8V maximum; 10K to +12V_RTN 4 VDD is an internal voltage rail derived from VSB and an internal housekeeping rail (“diode ORed”) and is compatible with the voltage tolerances of VSB).
