The following figure shows the outlet groups for three-phase PDUs.
North America, South America,
Japan, and Taiwan
Vertical rack-mounted PDUs that
occupy no rack unit (RU) space.
Each PDU has one 60 A inlet
circuit. Each phase supplies a
maximum of 40 A. Output is 23 A
(maximum) for each phase.
The PDU supports AC input
voltage levels from 200 to 240
VAC. The domestic PDU is used
with 60 A 208 V three-phase Wye
service.
Each PDU can supply 14.4KW of
power. The inlet cable has a plug
style that is an IEC309 60A 4 Pin.
in six groups of seven. Each phase
drives two groups on the PDU.
Phase 1 supplies power to group 0
and 3. Phase 2 supplies power to
group 1 and 4. Phase 3 supplies
power to groups 2 and 5.
All 42 outlets are IEC60320 C13
style receptacles. The C13
receptacle can supply 10A.
Note: If two outlets are configured
to draw 10 A each, the remaining
five outlets in the group cannot be
used.
Each group of seven outlets have a
20 A rated circuit breaker that can
be re-set.

Vertical rack-mounted PDUs that
occupy no RU space.
Each PDU must have one 60 A
inlet circuit. Each phase supplies
a maximum of 40 A. Output is 23
A (maximum) for each phase.
The PDU supports AC input
voltages from 200 to 240 VAC.
The European PDU is used with
25 A 380 VAC three-phase Wye
service.
Each PDU can supply 14.4 KW of
power. The inlet cable has a plug
style that is an IEC309 32A 5 Pin.
All PDUs have 42 outlets
arranged in six groups of seven.
Each phase drives two groups on
the PDU. Phase 1 supplies power
to group 0 and 3. Phase 2 supplies
power to group 1 and 4. Phase 3
supplies power to groups 2 and 5.
All 42 outlets are IEC60320 C13
style receptacles. The C13
receptacle can supply 10A.
Note: If two outlets are
configured to draw 10A each, the
remaining five outlets in the
group cannot be used.
Each group of seven outlets have
a 20 A rated circuit breaker that
can be re-set.
