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
