Product overview
AN17(F) Series aircraft ground solid-state power supply delivers stable, high-quality 400 Hz intermediate-frequency power for civil and military aircraft during ground maintenance, engine start, and onboard equipment servicing. The unit employs pure digital control based on high-performance FPGA processors and a novel 12-pulse rectifier topology to ensure low harmonic distortion, fast dynamic response, high power factor and efficiency, minimal mains pollution and high operational reliability. The design meets outdoor use requirements with IP55 protection and an operating range of -40 °C to +60 °C. Compared with the previous generation, the AN17(F) Series offers approximately 30% volume reduction and higher power density. Multiple invention patents underline its advanced design.

Product features

• Strong overload capacity: withstands 4× rated power for 1 s.
• Excellent output waveform: harmonic content <2%.
• Interlocking power supply function to ensure safe power delivery to aircraft.
• “Black box” logging for simplified maintenance and fault recording.
• Operating temperature: -40 °C to +60 °C; protection: IP55 (suitable for outdoor use).
• Compact footprint, high power density, reduced weight, high efficiency and low acoustic noise.
• Multiple configurations: vertical, trailer-mounted, and bridge-mounted integrated designs; high modularity and reliability.
• Advanced 12-pulse rectifier: input current distortion <5%, input power factor >0.96.
• Automatic voltage-drop compensation to ensure accurate voltage at the aircraft connector.

Product application
The AN17 Series single units support parallel expansion to form centralized high-capacity systems when combined with distribution cabinets, voltage-drop compensators and accessories. Typical use cases include maintenance hangars and military aprons with multiple parked aircraft: units are paralleled via distribution cabinets to feed several aircraft positions, with optional per-route voltage-drop compensators for automatic cable compensation. The system auto-identifies master and slave units by power-on sequence; the first unit to power on becomes master. Intelligent control automatically starts/stops units according to load or aircraft count. In case of a unit failure, the system isolates the faulty unit without affecting remaining units.
