APA-4G (АПА-4Г - Аэродромный подвижный электроагрегат) - mobile power supply for aviation ground support


The APA-4G is designed for single and group starts of aircraft engines with 24/48 V and 70 V voltages, with a maximum current of up to 2800 A. In addition, it allows the electrical power supply of the on-board electrical system during ground tests with DC voltages of 28.5 V and 57 V and AC single-phase voltages of 115 V / 400 (600) Hz, or with variable frequency in the range of 400-900 Hz.


The individual elements of the APA-4G are mounted on a special frame on the chassis of the Ural-375 / Ural-4320 automobile. APA-4G includes:
- DC voltage generator PR-600Ch2 (ПР-600Х2[/i:a656565c45fe])
- generators G108G ([i:a656565c45fe]Г108Г[/i:a656565c45fe]) and G107B ([i:a656565c45fe]Г107Б[/i:a656565c45fe]) with the possibility of regulating the output voltage frequency
- Pair of AKU batteries 12-ASA-145 (12-АСА-145[/i:a656565c45fe])
- cable system and cable feed system to aircraft (2x)
- control measurement and control system
