Tray Power
Factor
Correction
Power factor correction is applied within the power supply of each DE1600 drive tray,
which maintains the power factor of the drive tray at greater than 0.95 with nominal
input voltage.

Tray AC Power
Cords and
Receptacles
Each DE1600 drive tray is shipped with two AC power cords, which use standard AC
outlets in the destination country. Each AC power cord connects one of the power
supplies in the drive tray to an independent, external AC power source, such as a wall
receptacle, or to any uninterruptible power supply (UPS).
DC power is an option that is available for use with your DE1600 drive tray. For more
information, see "DE1600 Drive Tray Optional DC Power Connector Cables and
Source Wires."
