The base of the power supply unit of the TY-GPU140 towed aircraft power vehicle is installed on the trailer chassis. Its aircraft cover is formed by stamping metal sheet parts, which has good ventilation, rainproof and noise reduction capabilities. The appearance is flat and it has a large aircraft cover cabin door to facilitate maintenance personnel to repair the unit. This vehicle is composed of: an engine, a generator, a voltage regulation system, a frequency protection system, a voltage protection system, a load protection system, an output control system, an operating system, an output system and a trailer chassis, etc. The power supply vehicle adopts an intelligent integrated ECU control system. The unit takes noise reduction measures, and the noise level at a distance of 1 meter from the unit does not exceed 85 decibels.
This power supply vehicle meets the power supply requirements of the on-board electrical system for 400Hz AC/DC models. The power supply vehicle is equipped with a complete protection and dynamic regulation system, which can meet the stability requirements of frequency and voltage for aircraft using medium-frequency power supply. The power supply vehicle can work all day long and has excellent rainproof, waterproof, moisture-proof and anti-corrosion functions. It is also equipped with a rainproof device for cable plugs.
