Dell PowerEdge R730 Owner's Manual

PSU specifications

The PowerEdge R730 system supports up to two AC or DC redundant power supply units (PSUs).

Table 1. PSU specificationsFor 495 W AC, platinum power supply unit, the maximum heat dissipation is 1908 BTU/hr, frequency is 50/60 Hz, and voltage range is 100240 V AC autoranging. For 750 W AC platinum PSU, the maximum heat dissipation is 2891 BTU/hr, frequency is 50/60 Hz, and voltage range is 100240 V AC autoranging. For 750 W AC titanium PSU, the maximum heat dissipation is 2843 BTU/hr, frequency is 50/60 Hz, and voltage range is 200240 V AC autoranging. For 1100 W AC platinum PSU, the maximum heat dissipation is 4100 BTU/hr, frequency is 50/60 Hz, and voltage range is 100-240 V AC autoranging. For 750 W DC platinum PSU, the maximum heat dissipation is 2902 BTU/hr, frequency is 50/60 Hz, and voltage range is 100240 V AC and 240 DC. The 750 W DC PSU is applicable to China only. For 1100 W DC PSU, the maximum heat dissipation is 4416 BTU/hr and the voltage range is – (4860) V DC.
