Description
The MX2010 supports connection of a single-phase or three-phase
(delta or wye) AC PDM. Four AC PDM models are available: three-phase
delta, three-phase wye, seven-feed single-phase, and nine-feed
single-phase.
Each three-phase AC PDM requires two three-phase feeds to be
connected. Each phase from each of the two feeds is distributed
among one or two PSMs (one feed has each phase going to two
PSMs, and the other feed has each phase going to a single PSM).
The single-phase AC PDM provides an AC input connection from
the single-phase AC power source, and also provides an input
power interface to the PSM through a system power midplane.
The single-phase AC PDMs accept seven or nine AC power cords
from a single-phase AC source.
Each AC input is independent and feeds one PSM. Up to nine PSMs
can be connected through the AC PDM.
The MX2010 AC PSMs are hot-removable and hot-insertable. The AC
PSMs have a dual redundant feed (INP0 and INP1). One input feed is
active during operation. These feeds are set by the input mode DIP
switch located on the AC PSM (see
Description" on page 107). Each AC PSM works with a single phase
derived from either three-phase delta 200–240 VAC (line-to-line) or
three-phase wye 200–240 VAC (line-to-neutral). Each AC PSM is
capable of delivering 2500 W of power.
