EnerSys has Announced that Its PowerSafe DDm Line of Valve-Regulated Lead-Acid Batteries has Received NEBS Zone 4 Seismic Certification for 24 V and 48 V Configurations

EnerSys (NYSE:ENS), the worlds largest manufacturer, marketer and distributor of industrial batteries, has announced that its PowerSafe DDm line of valve-regulated lead-acid (VRLA) batteries has received NEBS (Networks Equipment Building System) Zone 4 seismic certification for 24 V and 48 V configurations.

Reading, PA (PRWEB) March 25, 2005 -- EnerSys (NYSE:ENS), the worlds largest manufacturer, marketer and distributor of industrial batteries, has announced that its PowerSafe DDm line of valve-regulated lead-acid (VRLA) batteries has received NEBS (Networks Equipment Building System) Zone 4 seismic certification for 24 V and 48 V configurations. This certification enables telecommunications customers in the wireline and wireless segments to install DDm battery systems in earthquake-prone regions for central office and wireless site applications.

In order to receive the NEBS Zone 4 rating, the EnerSys DDm 24 V and 48 V configurations underwent and passed a number of tests including flame retardancy; bonding and grounding; temperature, humidity and altitude effects; and earthquake office and transportation vibration. In addition, new steel framing able to withstand earthquake effects was certified by an independent third-party laboratory.

The cell design of the DDm incorporates thick 0.25" positive plates for an extremely long battery life of up to 20 years. The battery cells have welded epoxy, dual post seals that are 100% water bath tested in the factory and provide the highest seal integrity in the industry. Lead-casted terminal posts include a large threaded copper insert that enhances the high rate performance by providing maximum conductivity. This product line ranges from 200 to 2000 Ah at 25ºC (77ºF).

PowerSafe DDm battery cells are encased in dedicated protective steel modules that provide uniform and consistent compression for the life of the cell as well as cell protection during transport and installation. The modules design incorporates thermal management that allows maximum airflow and the one-piece container construction improves leak resistance. The design also enables flexible configuration as well as cost-effective, fast and easy installation, even in difficult locations.

Unlike competitive systems, the EnerSys battery cells do not have to be removed from the modules during installation. Users simply set up the rack and install the modules in configurations of 2, 3, 4 or 6 cells wide and up to 8 cells high. The DDm line is NEBS certified to 6 high for the DDm125 series and 8 high for DDm50/85/100 series. The system provides complete front access of the batteries for easy maintenance. Top termination is standard for shorter connections to the overhead bus, with optional side termination available.

PowerSafe DDm batteries provide minimized maintenance costs, using proven gas recombinant VRLA technology that eliminates the need for watering. In addition, a clear flame-retardant safety shield allows for easy visual inspection without battery removal.
