Power supply for the aeronautical industry AN27(F) Series

AC/AC

Product overview
AN27(F) Series 400 Hz intermediate-frequency solid-state power supply integrates advanced power electronics and intelligent digital control based on a high-performance FPGA. It provides a clean waveform with strong transient and steady-state behavior, designed for professional power-supply requirements in equipment testing and maintenance for aviation, radar, shipboard and related applications.

Product features

• FPGA-based digital control combined with SPWM high-frequency pulse-width modulation and isolation-transformer filtering to ensure waveform quality and stable operation.
• Sustained overcurrent capability: designed to withstand shocks up to 3× rated current to meet impact-type equipment test and maintenance needs in military and aerospace contexts.
• Real-time protection and monitoring for key components (IGBTs, transformers, input/output), with audible and visual alarm outputs.
• Modular architecture enabling straightforward maintenance and capacity expansion.
• Intelligent temperature-based fan-speed control for efficient cooling and reduced acoustic emissions.
• Safety key-lock function to prevent unintended operation.
• Rich remote-control interfaces (optional): RS485, RS232, GPIB, Ethernet and analog control options for remote operation and integration.

Product application
Suitable for aviation test benches, radar equipment testing, shipboard systems, military factories, hangars and research & production units requiring intermediate-frequency solid-state power sources.
