Introduction
The 22.5kW Power System is a 3-phase, 10-slot chassis with 2.5KW Power Supply Units (PSUs) that
provides stable DC output power (12.5VDC / 1800A). This 21-inch power system uses up to 10 high-power,
hot-swappable PSUs for flexibility in full power or redundant operation. For more information about the
22.5kW Power Shelf, refer to the
Lite-On 22.5kW Power Shelf Datasheet
.
The 2.5kW PSUs efficiently supply both main output DC power and standby DC power from either AC or DC
sources. These compact PSUs provide 2.5kW, 12.5V / 200A for main power output and 30W, 12V / 2.5A for
standby power applications. In addition, they support PMBUS 1.2 with boot loader, LED status indicators,
and circuit protection features. For more information about the 2.5kW PSU, refer to the
Lite-On 2.5kW
Power Supply Unit Datasheet
