The VBB Series power supplies are efficient high performance switching power supplies
with battery charger and power supervision, capable of providing two outputs, user
selectable for 12 or 24 VDC. One output provides continuous output power and the
second is programmable to either fail-safe or fail-secure lock operation, when the on
board fire alarm interface is activated. On-board visual indicators allow for immediate
installer feedback. Independent form C relay contacts are provided to report AC
and system fault conditions to remote or auxiliary equipment. The VBB Series are
uninterruptible power supplies when stand-by batteries are connected. VBB power
supplies are fully fault protected and feature fiberglass printed circuit boards to protect
the electronics from water and other corrosive elements. High efficiency design
promotes low heat generation leading to longer service life. These power supplies are
RoHs compliant, lead-free, and meet the latest state, federal and European requirements
for energy efficiency.
