Auxiliary Power Unit – A12011
A12011 / ONBOARD AUXILIARY POWER Auxiliary Power Unit – A12011
The Auxiliary Power Unit – A12011 is a compact onboard auxiliary power system developed to maintain essential armored vehicle systems when the main engine is switched off or unavailable. It supports electrical, pneumatic and hydraulic subsystems, onboard climate control and mission equipment while reducing dependence on continuous main-engine operation.
Compact auxiliary power platform for embedded or external vehicle integration, silent-mode operation and mission-system support.
Compact Auxiliary Power for Armored Vehicle Systems
The Auxiliary Power Unit – A12011 supplies power to selected vehicle subsystems without requiring continuous operation of the main engine. It supports onboard systems during pre-mission weapon testing, system checks and main-engine cooling, while also providing auxiliary power when the primary engine is unavailable or damaged.
The supplied technical table specifies 28 VDC output voltage, 6 kVA continuous power, 8.4 kVA output power and a maximum current of 210 A.
Embedded or External Integration for Military Platforms
The A12011 is intended for tracked and wheeled armored vehicles, tactical and support vehicles, and stationary military systems. Compatible platform examples include main battle tanks, infantry fighting vehicles, armored personnel carriers, MRAP vehicles and related armored systems.
The system can be embedded within the vehicle structure or installed externally according to platform requirements. Internal installations may use sound-insulated compartments, while external mounting can support heat dissipation and packaging requirements.

Power Architecture for Increasing Onboard Loads
The broader APU architecture described in the supplied information supports configurations from 2 kW to 20 kW and provides 24/28 VDC as well as higher AC and DC voltage options depending on the application.
The A12011 is integrated with the vehicle fuel and control systems and draws fuel directly from the vehicle fuel tank. The supplied information states that it does not require a dedicated battery or fuel reservoir. Air-cooled or liquid-cooled diesel architectures may be configured according to application requirements; the A12011 technical table specifically lists Water Cooled.
A12011 Auxiliary Power Features
Main-Engine-Off Power
The A12011 supplies selected onboard systems without requiring the vehicle's main engine to remain running.
Silent-Mode Support
Auxiliary operation reduces reliance on the main engine during low-signature stationary missions.
Co-Generation Capability
The APU can monitor vehicle power demand and compensate for electrical shortfalls alongside the main generator.
Vehicle Fuel Integration
The system draws fuel directly from the vehicle fuel tank without requiring a separate fuel reservoir.
