Aeronautical maintenance power supply AN28(F) series

for aircraft maintenancefor aircraftfor the aeronautical industry

Product overview
The AN28(F) Series programmable intermediate-frequency solid-state power supply integrates advanced power electronics and intelligent control for professional equipment testing and maintenance in aviation, radar, naval systems and similar fields. It is suitable for military factories, land/sea/air forces, civil aviation, hangars, and R&D/production units. The series is based on a high-performance FPGA as the central processor and combines digital control with advanced waveform management to deliver pure waveform output and excellent transient and steady-state performance.

Product features

• FPGA digital control combined with SPWM high-frequency PWM and isolation transformer filtering, ensuring high power density and system stability.
• Programmable functions including step, staircase and gradient to meet diverse test sequences for laboratory and test environments.
• Shock tolerance: can withstand 3× rated current for impact testing, meeting military and aerospace maintenance requirements.
• Comprehensive protection and monitoring of key components (IGBTs, transformers, I/O), with audible and visual alarms.
• Large color LCD for clear status and parameter display.
• Modular system design for simplified maintenance and functional expansion.
• Intelligent fan-speed control based on temperature to minimize acoustic noise.
• Key-lock safety function to prevent unintended operation.
• Multiple remote-control interfaces available (RS485, RS232, GPIB, Ethernet, analog) for flexible integration.

Product application
Designed for professional power supply needs in testing and maintenance of aviation, radar and shipboard equipment, and widely used in military factories, armed forces, civil aviation, hangars, and research and production facilities.
