Preen AMV Series

Ground power for aircraft on the tarmac, at test flight stations, or during field maintenance can't rely on lab-grade equipment built for indoor use — it needs to survive dust, moisture, temperature extremes, and physical handling while still delivering the precise 400Hz power aircraft electrical systems require. Preen's AMV series is built specifically for this environment: a rugged 400Hz ground power unit for airports, hangars, test flight stations, and field aircraft maintenance.

IP54 ingress protection is built into the AMV's standard design, not offered as a costly add-on — a meaningful distinction, since genuinely field-deployable equipment needs that protection as baseline, not an upsell. The unit operates across a -40°C to 55°C range, covering everything from arctic ground operations to desert tarmac conditions, and is available either as a stand-alone rack unit or as a fully self-contained trailer for true field mobility between sites.

Output covers 115/200V at 400Hz fixed, or 300-500Hz adjustable for broader frequency-variable testing, with overload capability scaling from 125% sustained for 600 seconds up to an optional 300% for 1 second — covering both sustained load conditions and brief transient demands during aircraft system start-up or testing. The unit is MIL-STD-704 compliant, the governing standard for aircraft electrical power quality.
