Power requiremements

The input current, power (VA), and dissipation per enclosure listed in this document are based on measurements of fully configured enclosures under worst-case operating conditions. Use the operating maximum values to plan the configuration of your storage system. These values represent either:

the values for a single power supply line cord, or
the sum of the values shared by the line cords of the combined power supplies in the same enclosure, with the division between the line cords and supplies at the current sharing ratio (approximately 50% each).

A failure of one of the combined power supplies per enclosure results in the remaining power supply supporting the full load. You must use a rackmount cabinet or rack with appropriate power distribution, and have main branch AC distribution that can handle these values for each enclosure in the cabinet.

Table 1. AC power specifications
Requirement	Description
AC line voltage	100 to 240V AC ± 10%, single-phase, 47 to 63 Hz
AC line current (operating maximum)	2.9 A max at 100V AC

Power factor	0.9 min at full load at 200V AC
Heat dissipation (operating maximum)	1.01 x 10⁶ J/hr (959 Btu/hr) max at 100V AC
Heat dissipation (operating maximum)	1.01 x 10⁶ J/hr (945 Btu/hr) max at 200V AC
In-rush current	30 A max for ½ line cycle, per line cord at 240V AC
Startup surge current	25 A peak max per line cord, max at any line voltage
AC protection	10 A fuse on each power supply, both Line and Neutral
AC inlet type	IEC320-C14 appliance coupler, per power zone
Ride-through time	30 ms min
Current sharing	Droop Load Sharing
NOTE: Ratings assume a fully loaded DAE that includes 2 power supplies and 12 worst case disk drive slot numbers. All power figures shown represent max normal operating numbers with the chassis running in a normal 20°C to 25°C ambient temperature environment. The chassis power numbers given may increase when running in a higher ambient temperature environment. For specific product configuration power numbers, refer to the EMC Power Calculator located on the internet at https://powercalculator.emc.com. The Power Calculator will provide the chassis power delta when operating in different ambient temperature ranges and configurations. However, it will only support products with an input voltage range of 200-240V ac.

Table 2. DC power specifications

Ride-through time	5 ms min. (test condition: Vin = -40V DC)
Current sharing	Droop Load Sharing
NOTE: Ratings assume a fully loaded DAE that includes 2 power supplies and 15 maximum disk slot numbers. All power figures shown represent max normal operating numbers with the chassis running in a normal 20°C to 25°C ambient temperature environment. The chassis power numbers given may increase when running in a higher ambient temperature environment. The EMC Power Calculator does not support DC chassis.
