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 power supply. According to user requirements, static power supplies ranging from 0.5kVA to 180kVA can be produced. The voltage amplitude regulation adopts space vector pulse width modulation technology
(Sinusoidal Pulse Width Modulation), so that the static power supply still has extremely low harmonic content when the output load and input power supply change, maintaining good dynamic performance. Mobile, fixed, bridge-mounted and trailer-mounted versions can be provided according to user requirements.
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 technology gives it excellent dynamic characteristics and low distortion. It causes little pollution to the mains power grid, has no inrush current, and the three-phase output voltage can be adjusted independently. It has strong overload capacity (AC), with automatic line voltage drop compensation function and comprehensive fault self-diagnosis function, making the power supply's protection measures complete, which can ensure the safety of aircraft, equipment and operators, with 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 fault repair time is less than 3 hours
6. Service life > 10 years, fault-free 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 have undergone relevant electromagnetic compatibility treatment before leaving the factory:
Technical indicators:
Input voltage: 220V ±10%, 380V ±10%
Input phase: single-phase, three-phase four-wire system:
