Honeywell 2MLR-AC23 Redundant Power Supply Module

The Honeywell 2MLR-AC23 is a high-capacity redundant power supply module designed for Honeywell MasterLogic-200 CPU units, specifically models 2MLR-CPUH/T and 2MLR-CPUH/F. Operating on a nominal 200–240 V AC supply, it provides a regulated 5 VDC output at up to 8.5 A to power processors and system backplane assemblies in dual-power configurations.

Power Conversion and Redundancy Integration

The module accepts an input voltage range of 200–240 V AC, converting utility power into a high-current 5 VDC backplane supply line. Engineered specifically for redundant power operation with 2MLR-CPUH processors, it works alongside a parallel power supply unit to maintain continuous rack operation without interruption if a primary source failure occurs.
