48VIT80LAHR 1U
Cabinet-Mounted
Battery Reserve
Module for Cabinet
Applications
Overview
The 48VIT80LAHR 1U cabinetmounted battery reserve module
is an intelligent versatile electronic
fully integrated reserve system that
deliveries energy storage to support
load during AC power line disturbances
and outages. The 48VIT80LAHR is the
first of the 48VIT80LAHR family of
batteries. Its technology is lead acid
(LA) and is designed for High Rate
(HR) discharge float applications. This
module is designed for standard rackmount applications and is feature
rich when used with GE Critical
Power systems and controllers.
The 48VIT80LAHR battery reserve
module is utilized in standard Edge Power
Cabinet applications in data centers and
enterprise applications. Connectivity
with the Galaxy Pulsar Edge controller
facilitates a multitude of battery
management functions and features.
48VIT80LAHR battery module is designed
around reserve systems requiring rapid
battery discharge rates that are typical
in today’s data center applications.
This battery module supports a rapid
recharge that minimizes the time period
between unprotected AC line outages.
48VIT80LAHR battery modules are
designed to be light weight such that
they can be safely handled by a single
technician. These modules are enclosed
entirely in a sturdy metal enclosure and
are made to be plugged into and easily
removed from the reserve system. The
Output battery voltage is internally
disconnected from the module’s
pluggable connector upon removing
the module from the system. Thus, the
servicing technician and other potential
contact surfaces are not exposed to
any hazardous energy contacts from
the battery when it is not installed.
These battery modules are fully
assembled, integrated, factory tested
and are maintenance free. 48VIT80LAHR
battery modules are constructed
using high-discharge capable valve
regulated lead acid batteries.
