400Hz Power Supply / Ground Power Unit AMV/AMF Series

400Hz Power Supply / Ground Power Unit AMV/AMF Series

The AMV / AMF Series are professional ground power units (GPU) designed in compliance with MIL-STD-704F. These systems are available in both stand-alone and trailer-mounted configurations, making them suitable for a wide range of aviation, industrial, and assembly-line applications.

The AMV / AMF series provide a stable output voltage of 115 / 200V or 115 / 200V ±10% with easy voltage adjustment. A fixed 400Hz output is standard, while adjustable frequency options are available depending on the model. With robust overload capability and rugged enclosure design, these units are ideal for hangars, product assembly lines, and harsh operating environments.
