AC Power Input
The AC power sources must provide the correct voltage, current, and frequency
specified on the tray model and serial number label. The tray can run without
interruption within the limits shown in
DC Power Input
The DC power source must provide the correct voltage, current, and frequency
specified on the array nameplate label and the serial number label.
Nominal input voltages for the DC power source are as follows:
■
Input voltage: –42 to -60VDC
■
Operating current: 21.7 to 15.3A
Controller Tray Power Factor Correction
Power factor correction is applied within the power supply, which maintains the
power factor of the controller tray at greater than 0.95 with nominal input voltage.
Power Cords and Receptacles
Sun Storage 2500-M2 Arrays are shipped with either two AC power cords or two DC
power cords per tray, depending on the configuration ordered.
AC Power Cords
Each AC power cord connects one of the power supplies in a 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.
