O-BBS 24-1080 and 48-540
Outdoor Battery Backup System
Key Features
•High capacity passive hydrogen
ventilation system — reliable
ventilation capacity exceeding
industry standards to minimize risk
of hydrogen build up
•Two separate compartments,
battery and electronics — no
risk for arcs or sparks to ignite
hydrogen gas as electronics
compartment is located below
batteries
•Outer skin made of 1/8" thick
powder coated aluminum —
corrosion resistant and shot gun
resistant
•Heavy duty foil backed
insulation in battery
compartment — minimizes
environmental impact and cooling
requirement
•Multiple and flexible cable inlet
positions — simple adaptability to
site conditions
Outside Plant for
Business-Critical Continuity
Description
The system includes innovative temperature control for the ultimate in reliability and long
life time. The O-BBS is state of the art engineering with extensive software analysis as well
as extensive agency testing and verification to the highest industry standards. Further
engineering focus was on installability/serviceability and cost.
DC Power
• +24VDC or –48VDC configurations — flexibility to connect to all common DC power
voltages
• Integrated Battery Breaker Module, BBM — flexibility to choose up to four feeds with
circuit breakers up to 200A each
Cooling and Heating
•Thermoelectrical cooling/heating
(Peltier) — high reliability and low maintenance cost
•No refrigerants used — environmental friendly and no requirement for specialized
refrigerant service technicians
•DC operated cooling/heating, i.e. no AC power routing required — saves site installation cost and time
•Low Voltage Disconnect device — automatic disconnect and reconnect of Peltier unit maximizes backup time and minimizes recharge time
•Thermostatically controlled by solid state circuit — high reliability and precise control
Application
Emerson Energy Systems’ O-BBS is a high
performance battery backup system for
outdoor applications. Usage can be for, but
not limited to:
•Extended RBS/BTS/data/telecom outdoor
battery backup
•Replacement of diesel generator sets
•Replacement of existing battery backup
solution to increase system reliability and
battery life
•Outdoor enclosure and shelter sites
