WISCO International (Newmar - Power Function Manager)

The Power Function Manager (PFM-400) is a system integrating component which converts ordinary rectifiers, power supplies or NEWMAR Power Modules into a fully integrated and multifunctional power system.
It provides control, monitoring, paralleling and circuit distribution and protection of 48 VDC, 24 VDC or 12 VDC power sources, in positive ground or negative ground applications.

Power Function Manager 200

Model: PFM-400 with optional load distribution circuit breakers installed

The Power Function Manager provides a heavy duty 400 amp parallel input tie point, digital DC output voltage and amperage metering, system and battery status lights, up to five individual load distribution circuits, low voltage battery disconnect (ideal for telecom systems with battery back-up) and summary alarm contacts, all combined in a compact, rackmount housing which serves as a master DC power management and distribution center. A 400 amp rackmount ground bus bar is also provided standard.

The PFM may be used for integration, control, monitoring and protection of numerous different types of DC power sources, such as AC-DC rectifiers, regulated DC power supplies or DC-DC converters. Note: Installation of oring diodes is recommended for paralleling of most power sources. Oring diode output is standard on NEWMAR's PM Series Power Modules
