BM Battery Shelf & Module System

BM Series Battery Module with BMS Shelf is an all-in-one, easy-to-assemble, 2RU, plug-and-play, reserve power system that accommodates two 48, 24 or 12 VDC battery modules. (The shelf and modules are sold separately.) No need for sourcing and installing separate batteries, battery trays, interconnect cable, terminals, or lugs.

The battery modules slide easily into the shelf and are secured in place with rear retaining pin and front panel latch. Plug-in connector assemblies provide for quick connection system load and/or paralleling multiple Battery Modules to meet higher run time requirements.

BM Series Battery Module internal batteries are sealed, maintenance-free, and easily replaced after a typical life of 3-5 years (standby). The input/output connectors are keyed to prevent reverse polarity hook-ups. A battery on-line circuit breaker / switch protects against overload and enables selective individual module load testing without interrupting continuity of the overall battery string.

Mounting brackets provided adapt for both 19" and 23" racks, 6" forward mount configuration. Flush (cabinet) shelf mounting and "universal" mounting of individual modules are available as options.
