Auxiliary Power Units (APU)

Uninterrupted 28 VDC with the main engine off — Silent Watch

Running an armoured vehicle's main diesel engine just to power its electronics during a surveillance task burns fuel and gives the vehicle away acoustically and thermally. Auxiliary power units (APU) solve this by powering mission electronics at 28 VDC with the main engine off — a capability known as Silent Watch.
