This series of products adopts high-frequency power electronic switching conversion technology and is specifically designed and manufactured for aviation and military electronic and electrical equipment as a 28.5V DC power supply. It can be used in aircraft and airborne equipment, radar, navigation, and other military electronic devices, as well as other applications requiring a 28.5V DC power supply. It serves as a next-generation replacement for thyristor power supplies.

Performance Features

1. The power supply utilizes a new generation of IGBT power devices, leveraging the advantages of high-frequency, low-loss operation in switching mode to achieve power conversion. It features compact size, light weight, high efficiency, and high reliability.

2. Current mode control employs full-bridge conversion, PWM control, and slope compensation technology, eliminating the need for series anti-saturation capacitors. It offers fast dynamic response, strong capability to withstand impact loads, and reliable overcurrent protection.

3. Intelligent monitoring is achieved through a micro single-chip computer, which oversees the power supply's operation. An LED/LCD digital panel displays operational parameters and status. It includes a self-diagnostic function that records recent faults, enhancing maintainability.

4. All functional units and components are designed with a modular structure. Expansion is achieved through series connection of modules, resulting in a compact size, high efficiency, and excellent reliability and maintainability.

5. The entire unit adopts a 19-inch standard chassis structure, suitable for standalone use or rack mounting.
