Storage Battery Systems Inc. offers the OSP Series for any uninterruptible power system application requiring high capacity or extended runtimes. Although able to perform in long duration discharge profiles, the extremely robust design of the cell internals lends itself to the stresses encountered by rapid high ampacity discharges found in most critical data power environments supported by a UPS. The OSP offers very high power density & a 25 year design life. Fully insulated, copper conductor intercell connectors with stainless steel fasteners present zero hazardous voltage to personnel. Unique "flip-top" arrestor vent caps facilitate the 1-3 year watering intervals. The post design is triple sealed & virtually leak-proof. The cover & case are flame retardant ABS & SAN respectively as standard. Economical Seismic Zone 4 racking is available to further take advantage of the high density, low footprint design. The 5 year 100% warranty assures you of solid manufacturing processes.
