PSU specifications

The PowerEdge R430 system supports up to two AC redundant power supply units (PSUs) and a single AC cabled PSU.

Table 1. PSU specificationsFor 550 W AC, platinum power supply unit, the maximum heat dissipation is 2107 BTU/hr, frequency is 50/60 Hz, and voltage range is 100240 V AC autoranging and the current rating is between 7.4 A-3.7 A. For 450 W AC Bronze PSU, the maximum heat dissipation is 1871 BTU/hr, frequency is 50/60 Hz, and voltage range is 100240 V AC autoranging and the current rating is between 605 A-3.5 A.
PSU	Class	Heat dissipation (maximum)	Frequency	Voltage	Current
550 W AC	Platinum	2107 BTU/hr	50/60 Hz	100–240 V AC, autoranging	7.4 A-3.7 A
450 W AC	Bronze	1871 BTU/hr	50/60 Hz	100–240 V AC, autoranging	6.5 A-3.5 A

NOTE Heat dissipation is calculated using the PSU wattage rating.

NOTE This system is also designed to connect to the IT power systems with a phase-to-phase voltage not exceeding 230 V.
