Product Performance
- High – precision voltage regulation: With a voltage regulation accuracy of ±0.2%, it can firmly control the generator terminal voltage deviation within a very small range when the load changes significantly, providing high – quality and stable voltage output for the power grid.
- Fast response characteristics: The response time is no more than 5ms, which can quickly respond to situations such as grid faults and sudden load changes, effectively suppressing voltage fluctuations and significantly improving the dynamic stability of generators and grids.
- Full – function control integration: Integrates multiple control modes such as AVR, VAR, and PF. Users can flexibly customize the control logic through professional software to adapt to different working conditions of the generator, such as stand – alone operation and grid – connected operation.
- Perfect protection mechanism: Multiple protection functions monitor the excitation system in real – time. Once abnormalities such as overexcitation and synchronization failure occur, the excitation output can be cut off in a very short time, comprehensively ensuring the safety of the generator and grid equipment.
- Strong environmental adaptability: The operating temperature range is from – 40°C to +70°C, and the protection class reaches IP54. It can effectively resist dust and low – pressure water splashing, and can operate stably in complex scenarios such as outdoor power plants and harsh industrial environments.
