Auxiliary Power Unit – M2312
M2312 / AC & DC AUXILIARY POWER Auxiliary Power Unit – M2312
The Auxiliary Power Unit – M2312 is an onboard auxiliary power system developed to maintain critical military vehicle systems when the main engine is switched off or unavailable. Its architecture supports both AC and DC power requirements while supplying electrical, pneumatic and hydraulic subsystems, onboard climate control and mission equipment across demanding operational conditions.
Modular AC and DC auxiliary power platform for main-engine-off operation, co-generation and multi-system military vehicle integration.
Integrated AC and DC Auxiliary Power for Military Platforms
The Auxiliary Power Unit – M2312 provides uninterrupted power to selected vehicle systems without requiring continuous operation of the main engine. It supports pre-mission weapon and system testing, onboard diagnostics and main-engine cooling, while helping essential equipment remain operational if the primary engine is damaged or unavailable.
The system also extends onboard power availability in deployment areas where fixed external power infrastructure is not available.
Modular Integration Across Ground, Stationary and Airborne Systems
The M2312 is intended for tracked and wheeled armored vehicles, tactical and support vehicles, stationary systems and airborne platforms. Supplied application examples include main battle tanks, self-propelled artillery systems, armored and infantry fighting vehicles, armored personnel carriers, MRAP vehicles, rocket systems, shelters, tents, helicopters and aircraft.
Depending on vehicle architecture and mission requirements, the system can be installed inside a sound-insulated compartment or externally on the platform structure to address thermal dissipation, acoustic management and integration requirements.

kVA
Dual AC/DC Architecture for Diverse 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. For the M2312 specifically, the technical table lists 230 VAC with 4 kVA continuous AC power and 28 VDC with 10,5 kVA continuous DC power.
The system draws fuel directly from the vehicle fuel tank and does not require a separate fuel tank or battery. Depending on application requirements, air-cooled or liquid-cooled diesel architectures may be configured; the M2312 technical table specifically lists Water Cooled.
