Introduction to 400HZ Intermediate Frequency Power Supply:
The 400HZ ground static power supply inverts 50Hz mains power into 400Hz, 115/200V three-phase AC intermediate frequency power supply. According to user requirements, static inverters ranging from 0.5kVA to 180kVA can be produced. The voltage amplitude adjustment adopts space vector pulse width modulation technology
(SPWM), which enables the static inverter power supply to have extremely low harmonic content even when the output load and input power change, maintaining excellent dynamic performance. Mobile, fixed, bridge-mounted and trailer-mounted versions can be provided according to user needs.
Product Features:
1. Pollution-free, low noise
2. The output has current limiting function, which can adapt to rectified impact loads,
3. Adopting space vector pulse width modulation (SV-PWM) technology endows it with dynamic characteristics and low distortion. It causes little pollution to the mains power grid, has no inrush current, and can independently adjust the three-phase output voltage. It has strong overload capacity (AC), is equipped with automatic line voltage drop compensation function, and has comprehensive fault self-diagnosis function, making the power supply's protection measures complete, which can ensure the safety of aircraft, equipment and operators, and features economical operation and high efficiency (90%)
4. Convenient operation and maintenance: Only the start and stop buttons need to be operated during daily operation. Users can check the power supply's operating parameters, operation records and fault information through the friendly display interface
5. The average time to repair a fault is less than 3 hours
6. Service life > 10 years, fault-free working time > 8000 hours
7. Equipped with remote control interface, which can meet the needs of on-site remote monitoring;
8. Main electrical components all adopt standard products from domestic and foreign manufacturers:
9. All power supplies undergo relevant electromagnetic compatibility treatment before leaving the factory:
