51303948-100 | Honeywell | Battery Backup Module

The Honeywell 51303948-100 is a 48 VDC battery backup assembly engineered to provide uninterruptible power to High-Performance Process Manager (HPM) and Advanced Process Manager (APM) equipment. It is deployed in critical distributed control system environments to prevent system interruptions and data loss during primary power failures.

System Integration and Redundancy Support

This backup assembly is commonly integrated into redundant cabinet layouts where high reliability is mandatory. It features a dedicated disconnect connector that facilitates seamless power transition when switching between primary and backup sources.

Power Capacity and Performance

The module delivers a stable 48 VDC output designed to sustain continuous operation for critical input/output processor loads. Under standard load conditions supporting up to 40 IOPs, a fully charged unit provides an approximate backup duration of 20 minutes.

Mechanical Design and Installation

Built with a compact tray form factor, the unit slides directly into standard Honeywell cabinet racks to optimize panel space. The assembly includes internal batteries configured for secure mounting within the rack enclosure.
