Product Performance

Adopting 32-bit RISC microprocessor and adaptive PID control algorithm, combined with high-precision A/D converter, it achieves voltage regulation accuracy of ±0.25% with response time ≤10ms, which can quickly adapt to load fluctuations and grid changes. The IGBT power module supports 10A continuous current output, compatible with synchronous generators ranging from 100kVA to 80MVA, meeting the needs of equipment with different power levels.

Built-in dual-channel redundancy design enables precise load sharing between parallel units, with load imbalance ≤1%. Integrated with rotating diode monitoring and automatic synchronization functions, it real-time diagnoses the status of power devices with synchronization error ≤0.5°, ensuring stable grid connection of parallel units. Supports NTP time synchronization and event log recording, fault information is uploaded to the monitoring system within 100ms, with diagnostic coverage ≥99%.

Modular structure facilitates expansion and maintenance, allowing component replacement without shutdown, adapting to 24/7 continuous operation scenarios. Industrial-grade protection design can resist electromagnetic interference and vibration impact in harsh environments, with Mean Time Between Failures (MTBF) ≥600,000 hours.
