28.5V DC ground regulated power supply / 270V high-voltage aviation ground DC power supply, aviation ground power supply, aviation DC power supply is a 28.5V DC power supply designed and manufactured for aviation and electronic and electrical equipment using high-frequency power electronic switching conversion technology, which can be used for various aircraft and airborne equipment, radar, navigation and other electronic equipment. This DC power supply is suitable for starting and maintaining business jets, corporate jets, helicopters and trainer aircraft, and is the main power supply equipment for aviation DC 28.5V, as well as other occasions requiring 28.5V DC regulated power supply, and is a replacement product for thyristor power supplies.
The 28.5V DC regulated power supply adopts the Air France high-speed chopper scheme, which does not require large-capacity inductors, capacitors and other filtering devices.
It fundamentally solves the problems of voltage overshoot and voltage deviation.
1. High stability and long service life;
2. Long-distance voltage drop compensation function for output leads to ensure the accuracy of terminal voltage under large current;
3. The closed-loop response speed reaches 1 second, and the isolated transformer structure is adopted to ensure the safety of the electrical structure.
4. The output stage adopts a non-high-frequency rectification scheme, which avoids the current-carrying out-of-control effect that is prone to occur in high-frequency rectifier devices, and ensures the safety performance of the system under high-current working conditions
.
Application occasions: DC28.5V ground DC power supply is widely used in aerospace, ground radar stations, ships, submarines, computer stations, military precision instruments and imported equipment power supply equipment.
Working modes: It has two working modes of constant voltage and constant current;
