The PowerSafe D range of batteries, available in both DU and DSG models, are designed for telecommunications, utility and switchgear applications. PowerSafe DU battery models are designed to handle the demanding float and deep discharges typical for telecommunication applications. They feature proven flat plate lead-calcium grid alloy and they’re the largest amp hour capacity four cell battery in the industry, ranging from 310 to 780Ah. The DU series multi-cell construction shortens installation time and reduces the battery string footprint. In addition, PowerSafe DU batteries are designed with the edge of the plates oriented perpendicular to the rack rails for full plate edge visibility. The dual hole (top/bottom) terminal design allows for easy maintenance.
PowerSafe DSG battery models feature a lead-calcium design that reduces the maintenance (watering intervals) associated with lead-antimony batteries. This makes the DSG battery ideal for challenging utility switchgear applications. Its 0.25 inch positive grids are one of the thickest in the industry, making it an excellent long discharge battery and ideally suited for the complex duty cycle requirements of the switchgear application. The multi-cell construction helps to minimize floor space. PowerSafe DSG batteries also have individual posts for each cell, to help ease and simplify the integration of battery monitoring and test equipment used in routine maintenance inspections. All PowerSafe D batteries employ a proven Slide-Lock post seal that allows for natural plate growth over time without degrading the seal. The innovative tongue-and-groove jar-to-cover seal provides reliability with a robust airtight seal.
Engineered to meet the requirements of the power industry with its industry leading features, PowerSafe G batteries are one of the best out there. The PowerSafe G product family features calcium plates which demonstrate maximized performance in long discharge applications, allow the battery to tolerate high temperatures and, along with extra thick positive grids, make the PowerSafe G family of batteries one of the most rugged on the market. As industry requirements for less maintenance increase, the PowerSafe G family continues to be a proven solution. They're designed with an electrolyte reserve for reduced watering requirements to allow for a longer water interval. Thick lead-calcium grids maximize performance and help to provide for 100% initial capacity out of the box. The placement of copper inserts within the posts maintains excellent short duration, high-current performance, while individual posts make monitoring individual cell performance possible.
The PowerSafe F range of batteries is specifically designed for the telecommunication industry including central office, cellular, and microwave applications. They range from 840Ah to 1810Ah and provide excellent long duration discharges. The PowerSafe F battery range consists of two models: FTA-P and FTC-P. PowerSafe FTA-P models utilize proven flooded flat plate antimony technology, while the PowerSafe FTC-P models use proven flooded flat plate calcium technology.
All PowerSafe F batteries feature a multi-directional design of the post, so the cells are easily configurable in any orientation, with cells either perpendicular to the rack support rails to optimize footprint or parallel to enable easy maintenance while the system is online. PowerSafe F batteries also employ EnerSys’ exclusive Slide-Lock post seal that allows for natural plate growth over time without degrading the seal and an innovative tongue and groove jar-to-cover seal to prevent leaks.
Vented Lead Acid batteries are most commonly used in central office applications or sites with a high capacity demand and a large allowable space for the battery system. 300-4000 Ah per battery equating to up to 8,000 Watts per cell. Flooded cells provide a much longer lifespan than their equivalent VRLA batteries but also require more maintenance than their VRLA counterparts.
