Introduction
The 3-Phase Power Supply System is a 10-slot chassis with 2.5KW Power Supply Units (PSUs) that provides
stable DC output power. This 21-inch power system uses up to 10 high-power, hot-swappable PSUs for
flexibility in full power or redundant operation.
There are different models of the 10-Slot Power Supply System depending on output power requirements
and input power configuration as shown in the table below.
3-phase Input Power Configuration
Model Number
Line-to-Line 4-Wire System
PF-2223-1L1N – 10 slot single input
PF-2123-2LNN – 5+5 slot single input
PF-2223-1LDN – 10 slot dual input
Line-to-Neutral 5-Wire System
PF-2223-1L1M – 10 slot single input
PF-2123-2LNM – 5+5 slot single input
PF-2223-1LDM – 10 slot dual input
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.
This startup guide provides instructions to startup the 10-Slot Power Supply System for the first time. It
assumes that the 10-Slot Power Supply System has been properly installed and is ready for initial power up
and testing. Refer to Lite-On 3-Phase 22.5kW Power Supply System User Guide for installation instructions.
