The UBE-PWE is an undermount enclosure for Alpha’s PWE-3. The undermount battery expansion enclosure (UBE) increases capacity of PWE Series enclosures, providing space for three additional batteries. The UBE-PWE easily and quickly attaches below an existing PWE-3 pole-mounted enclosure. The UBE-PWE has several options including battery drawers, 120VAC or 240VAC battery heaters, AlphaGuard™ charge management system and a complement of battery cable kits. This enclosure can be added to all legacy PWE three battery enclosures manufactured by Alpha.
