28.5V Ground DC Regulated Power Supply / 270V High-Voltage Aviation Ground DC Power Supply. Aviation ground power supplies and aviation DC power supplies are 28.5V DC power supplies designed and manufactured for aviation and electrical and electronic equipment, using high-frequency power electronic switching conversion technology. They can be used as 28V power supplies for various aircraft, airborne equipment, radar, navigation and other electronic equipment, as well as 27V aviation DC power supplies and 27V regulated power supplies* - Jin Electromechanical Aviation DC Power Supply. This DC power supply is suitable for the start-up and maintenance of business jets, executive jets, helicopters, and trainer aircraft. It is the main power supply equipment for aviation DC 28.5V, and is also applicable to other occasions requiring 28.5V DC regulated power supplies. It is an upgraded product of thyristor power supplies.
The 28.5V DC regulated power supply adopts a French high-speed chopper scheme, eliminating the need for large-capacity filter components such as inductors and capacitors.
It fundamentally solves the problems of voltage overshoot and voltage droop.
1. High stability and long service life;
2. Output lead long-distance voltage drop compensation function, ensuring the accuracy of terminal voltage under high current conditions;
3. Closed-loop response speed reaches 1 second, and an isolation transformer structure is adopted to ensure the safety of the electrical structure;
4. The output stage uses a non-high-frequency rectification scheme, avoiding the current runaway effect that easily occurs in high-frequency rectification devices, and ensuring the safety characteristics of the system under high-current operating conditions.
Applicable occasions: DC28.5V ground DC power supplies are widely used in aerospace, ground radar stations, ships, submarines, computer stations, military precision instruments and meters, and power supply equipment for imported equipment.
Working modes: It has two working modes: constant voltage and constant current;
