APU for Urban Forces Vehicles
22kW AUXILIARY POWER UNIT APU FOR URBAN SPECIAL FORCES VEHICLES
Ref no. MVK-APU
A modular 22kW Auxiliary Power Unit (APU) (Derated 17kW in 55°C Ambient) with 28 VDC 270A (230A @ 55°C) brushless alternator to:
- Supply 28 VDC, 85A to charge the vehicle batteries.
- Supply 28 VDC, 85A for the air conditioning system.
- Belt driven 14kW ACU compressor.
The APU/ACU system does not restrict the standard operational features of the vehicle in terms of mobility. The APU system shares the vehicle’s batteries and fuel tank, but the system can be equipped with its own battery pack and fuel tank. The system uses quick coupler connections for easy APU removal without losing the refrigerant charge.
The electrical connections, looms between the aircon, power units, electronic control panels and electrical control gear are designed and selected for operation in military environments, which include adverse temperatures, EMI/EMC as well as severe shock and vibration.
The aircon and power units are equipped with custom designed electronic controllers, capable of all control and safety functions. The APU runs at a fixed speed, but automatic engine speed regulation is available as an optional extra. The system has a Bluetooth login interface for remote monitoring via a smartphone app and/or laptop. Installation of the units requires minimal vehicle modifications. SME can also “repackage” this system in an enclosure which would fit any client’s requirements.
