Power and
Voltage-Switching Unit (PVSU)
Features
• The PVSU combines and modernizes the three most common military ground-mobile power handling
LRUs (PDU, PSU, & VSU)
• The PVSU utilizes state-of-the-art, self-protected, BIT capable, “Smart Power” switching hybrids and interface circuitry
• The PVSU unites an intuitive operator interface with military HFE designed displays and controls
• The PVSU provides full BIT/BITE, diagnostics, and fault isolation
• The PVSU is the easily integrated, full military environment qualified power handling solution for legacy Platform
upgrades and new platform designs
Description
The power distribution portion current limits, filters and distributes the platform’s prime power source to the platform’s
DC power grid
• Power system faults are displayed and communicated on the CAN Bus
• Electronic “circuit-breakers” can be reset locally or remotely via the CAN Bus
The power select portion allows the user to switch between various platform and external power sources
• NATO (28V) Receptacle, Auxiliary Power Unit, Shore Power (AC), Inverter outputs, etc.
The voltage switching portion displays the State of Health (SoH) for the battery bank(s), the ac input/inverter outputs, and
provides optional Battery Bank switching for isolation, load switching, battle-override, and emergency starting functions.
