Newmar Power Function Manager PFM-500

The Power Function Manager (PFM-500) is a system integrating component which converts ordinary power supplies into a fully integrated and multifunctional power system. The unit provides for control, monitoring, paralleling and protection of 12, 24 or 48 VDC, positive negative or floating ground power sources.

A 500 amp, heavy duty parallel tie point bus accommodates input from multiple/redundant rectifiers. A digital meter displays system bus voltage, battery voltage, total rectifier amperage, connect/disconnect voltage set points, and system ambient temperature. Features also include status lights, load distribution circuits, low voltage battery disconnect with alarm contacts. All these functions are combined in a compact, rackmount housing which serves as a master DC power management and distribution center. A rackmount ground/return bus is provided.

The PFM may be used for integration, control, monitoring and protection of numerous different types of power sources, such as AC-DC rectifiers, regulated power supplies, DC-DC converters and battery banks
