28.5V Ground DC Regulated Power Supply / 270V High-Voltage Aviation Ground DC Power Supply, Aviation Ground Power Unit, Aviation DC Power Supply adopts high-frequency power electronics switching conversion technology, designed and manufactured for aviation and electronic electrical equipment as a 28.5V DC power source. It can be used for various aircraft and airborne equipment, radar, navigation, and other electronic devices. This DC power supply is suitable for the startup and maintenance of business jets, private jets, helicopters, and trainer aircraft. It serves as the primary power supply equipment for aviation DC 28.5V and other applications requiring a 28.5V DC regulated power supply, representing an upgraded replacement for thyristor-based power supplies.
The 28.5V DC regulated power supply utilizes the Air France high-speed chopper solution, eliminating the need for large-capacity inductors, capacitors, and other filtering components.
It fundamentally resolves issues of voltage overshoot and voltage offset.
1. High stability and long service life;
2. Output lead voltage drop compensation function over long distances, ensuring terminal voltage accuracy under high current conditions;
3. Closed-loop response time reaches 1 second, employing an isolated transformer structure to ensure electrical safety.
4. The output stage uses a non-high-frequency rectification solution, avoiding the uncontrolled current-carrying effects common in high-frequency rectification devices, ensuring system safety under high-current operating conditions.
Applications: DC28.5V ground DC power supplies are widely used in aerospace, ground radar stations, ships, submarines, computer stations, military precision instruments, and imported equipment power systems.
Operating Modes: Features both constant voltage and constant current operating modes;
