10kW VPOC™ Power System
VP-3103-111U-UG-03 Page 3 of 23 September 2016
Introduction
Virtual Power On Call (VPOC™) is a highly-efficient backup power solution that uses a fraction of the space
of a conventional Uninterruptable Power System (UPS). The 10kW VPOC™ module, along with two Lithium
Ion (Li-ion) battery modules, slides into the 1U VPOC™ Shelf. VPOC automatically manages transitions
between normal (AC) operation and battery mode (DC) to keep IT equipment safe during power
interruptions. An external VRLA battery solution may be substituted for Li-ion batteries for even longer
backup times. For more information about the 10kW VPOC™ Power Shelf, refer to the Lite-On 10kW
VPOC™ Power Shelf Datasheet.
The 10kW Power Module efficiently supplies both main output DC power and standby DC power from
