PRODUCT DESCRIPTION

The 153M power plant is designed to provide distribution and monitoring of -48VDC. The plant is rated at 5000 Amps
(total 5000 rating includes main and supplemental bays). The -48VDC is fed through a 6000 Amp total discharge shunt that is bussed to a main bay and supplemental bays rated at 2500 Amps each. The main source of power for the 153M power plant is commercial AC that is converted to DC by the rectifiers. The 153M power plant provides system monitoring, alarming, and distribution of -48VDC to load circuits.

System operation is such that the rectifiers float the battery, charge the batteries as required, and provide current to the load circuits. Audible (optional) and visual alarms are produced by the meter and alarm panel when the battery float voltage deviates from system set points.
