Power requirements  Top

The following table describes the power requirements for the SDS12 disk shelf connected to two 20A circuits based on a maximum PSU load.

Volts

Amps per SDS12

100-240V

4.6-1.9A

Use the following graph to determine current allocation for each SDS12 power supply based on the worst-case minimum input voltage.

Power consumption and thermal rating  Top

The power consumption (in watts) and the number of BTUs per hour produced by the disk shelf depend on the number and type of devices (for example, power supplies, disks, and so on) installed in the disk shelf.

Average power consumption for one disk shelf

The following table gives an example of average power consumption for one disk shelf with 12 disks, 2 power supplies, and 3 fans.

Power consumption

Thermal rating

340W

1, 160 BTU/hr.
