Power factor correction is applied within the power supply, which maintains the
power factor of the controller-drive tray at greater than 0.95 with nominal input
voltage.

Cords and
Receptacles
Each E2600 controller-drive tray is shipped with two AC power cords. Each AC
power cord connects one of the power supplies in a controller-drive tray to an
independent, external AC power source, such as a wall receptacle or a UPS.
If you have a cabinet with internal power cabling, such as a ladder cord, you do not
need the AC power cords that are shipped with the controller-drive tray.
DC power is an option that is available for use with your controller-drive tray and
drive trays. For more information, see E2600 Controller-Drive Tray Optional DC
Power Connector Cables and Source Wires.
