3 Phase UPS overview
The HP 3 Phase UPS protects your sensitive electronic equipment from the most common power problems
including power failures, power sags, power surges, brownouts, and line noise.
Power outages can occur when you least expect it and power quality can be erratic. These power problems
have the potential to corrupt critical data, destroy unsaved work sessions, and damage hardware - causing
hours of lost productivity and expensive repairs.
With the HP 3 Phase UPS, you can safely eliminate the effects of power disturbances and guard the integrity
of your equipment. The HP 3 Phase UPS is designed for critical applications such as ultra high—density blade
servers in a data center environment.
Providing outstanding performance and reliability, the HP 3 Phase UPS unique benefits include:
• High-density three-phase input, three-phase output UPS
• Scalable to 60 kW (redundant N+1 configuration) by connecting up to six additional parallel UPS
modules.
Each UPS in the parallel system connects to a Power Bus Bar pre-installed in the rear of a rack. Racks
can be configured for bottom or top entry
A Parallel UPS Card in each paralleled UPS provides connectivity for system metering and operational
mode control. In a parallel system not fully loaded, the system will shift load to UPSs with the strongest
batteries or additional ERMs to maximize runtime when on battery. Parallel systems can be configured
for capacity or redundancy.
• 6U UPS height, 3U ERM height
• Normal operating mode that minimizes heat generation by operating at typically >98% efficiency
The UPS filters incoming AC power and provides consistent power to your equipment without draining
the battery.
• For utility line input that exceeds normal operating range, automatic transfer to an online,
double-conversion, high-frequency UPS design with pure sine wave output and power-factor correction
• EBM technology that uses advanced battery management to increase battery service life, optimize
recharge time, and provide a warning before the end of useful battery life
• Extended runtime with up to four ERMs per UPS
• Hot-swappable electronics module and batteries that simplify maintenance by allowing you to replace
them safely without powering down the critical load
• Emergency shutdown control through the REPO port
• HP UPS Management Module for network connectivity with monitoring and control
• Firmware that is service upgradeable through the standard DB-9 communication port
• Backed by worldwide agency approvals
