The 400Hz Single-phase Intermediate Frequency Power Supply (400Hz Power Supply) is specifically designed and manufactured for aerospace electronics and other equipment. It employs advanced and reliable high-frequency power electronic switching conversion technology, a modular structure, excellent output waveform quality, and strong load adaptability. Widely used in aircraft manufacturing and maintenance, airborne equipment, radar navigation, and other electronic devices that require 400Hz AC power. Product features:
High reliability and stability: Utilizing Sinusoidal Pulse Width Modulation (SPWM) design, with the inverter core featuring original imported Japanese Mitsubishi or German Infineon IGBT inverter modules and driver circuits, ensuring stable performance, reliability, and long service life.
2. Comprehensive Protection Features: Overcurrent, short-circuit, overvoltage, overheating, overload protection, and alarm functions ensure the safety of electrical equipment.
3. Fast Dynamic Response: Load surge drop less than 1%, response time less than 2ms.
4. High-load capacity, suitable for any type of load; rational application of power devices ensures continuous operation under load; utilizes AC-DC-AC structure with an isolated transformer for output isolation, compatible with any type of load.
5. Full input-output isolation ensures safety and reliability. Isolated transformers are used for output isolation, providing pure and stable waveforms, and guaranteeing safe and reliable output.
6. The three-phase power supply can accommodate any unbalanced load, utilizing an AC-DC-AC structure. The main circuit and control circuit of the three-phase power supply are designed as three separate single-phase power supplies, allowing any phase of the three-phase power supply to be used independently as a single-phase power supply, and can adapt to any unbalanced load.
