PBB2S - Battery Charger System

Product Overview

 

PBB2S Series Battery Chargers / DC UPS

The PBB2S Series is a family of 13.8Vd, 3.5A and 7A off-line battery chargers / DC uninterruptable power supplies which operate from 100-240Vac mains power. When connected to a valve regulated lead-acid (VRLA) battery, these units provide uninterrupted power to a DC load in the event of mains failure.

The PBB2S Series contains a two-step current limited float charger, output overcurrent and short circuit protection, a self-resetting battery fuse, overtemperature protection, and mains DC OK battery OK and battery fuse fail alarms

THe PBB2S is available in a light weight corrosion resistant aluminium chassis mount enclosure.  Both models employ natural convection cooling.  The PBB2S series is for indoor use only.
