PB256 - Battery Charger System

Product Overview

 

PB256 Series Battery Chargers / DC UPS

The PB256 Series is a family of 13.8Vdc and 27.6Vdc, 110W / 140W  off-line battery chargers / DC uninterruptable power supplies which operate from 220/240Vac mains power. when connected to a lead-acid battery.  These units provide uninterrupted power to a DC load in the event of mains failure.

The PB256 Series contains a two-step current limited float charger, battery charge current limiting, a battery low voltage disconnect and mains/charger and battery alarms. It employs high efficiency technology, combined with very low output noise that makes it suitable for powering broad range of loads such as security, radio, scada, control equipment and alarm systems etc.

The PB256 is available in chasis mount enclosure, and can be fitted into the WMBB wall mount box.  A supplementary heatsink is needed for 140W models to operate at maximum power.  All models employ natural convection cooling.
