PB314A -RM - Battery Charger System

Product Overview

 

PB314A Series Battery Chargers / DC UPS

The PB314A Series is a family of 13.8Vdc, 27.6Vdc and 55.2Vdc, 624W / 1056W  off-line battery chargers / DC uninterruptable power supplies which operate from 110/240Vac 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 PB314A contains a two step current limited float charger, battery charge current limiting AC mains rectifier and battery alarms, battery present detection and optional float voltage temperature compensation (option - T).  It employs high efficiency switching technology, combined with very low output noise which makes it suitable for powering a broad range of loads such as communication equipment, control equipment and alarm systems.

The PB314A is available with a 10BaseT / 100Base TX Ethernet interface (option -N).  This interface supports SNMP V1, XML and an embedded webpage allowing the PB314A to be monitored remotely.

The PB314A is available in 2RU 19" rack mount enclosure.

All models incorporate an alphanumeric LCD display as standard.
