NEWMAR's The power function manager is a system integrating component which converts ordinary power supplies (or Power Modules) into a fully integrated and multifunctional power system. The unit provides control, monitoring, paralleling, and circuit breaker distribution of 12, 24, or 48 VDC, positive, negative or floating ground power sources. A 500 A, 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.
