The following table lists the specifications for three-phase power distributions units (PDUs) in various countries.
Three-phase PDUs | North America, South America, Japan, and Taiwan | EMEA |
---|---|---|
Rack location | Vertical rack-mounted PDUs that occupy no rack unit (RU) space. | Vertical rack-mounted PDUs that occupy no RU space. |
Inlet circuits | Each PDU has one 60 A inlet circuit. Each phase supplies a maximum of 40 A. Output is 23 A (maximum) for each phase. | 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. |
AC voltage | 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. | 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. |
Power | Each PDU can supply 14.4KW of power. The inlet cable has a plug style that is an IEC309 60A 4 Pin. | Each PDU can supply 14.4 KW of power. The inlet cable has a plug style that is an IEC309 32A 5 Pin. |
Outlet groups | 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 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. |
Receptacles | 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.
