Product Performance

Control Performance: It has high-precision voltage regulation function. When the grid voltage fluctuates, it can automatically adjust the excitation output within 100 milliseconds, stabilizing the terminal voltage within ±0.5% of the rated value. It supports three regulation modes: AVR, FCR and PF VAR, and has boost control and FRT detection functions.

Adaptability Performance: Specially designed for synchronous motors below 3.5MVA, it can be adapted to synchronous motors in various scenarios such as land-based power plants, ships and traction. It shares software source code and simulation models with UNITROL 1010 and 1020, and supports Ethernet time synchronization and event time stamping.

Safety Performance: Equipped with a thyristor crowbar trigger trip external fuse device, it has complete overcurrent and overvoltage protection functions, which can effectively protect the safety of synchronous motors and excitation systems, meeting the requirements of harsh grid codes.

Stability Performance: Adopting industrial-grade design, it has strong anti-interference ability, is equipped with non-volatile flash memory to record operation data, and the IGBT-based output stage operates stably, which can run continuously for a long time in harsh industrial environments and has high reliability.

Operation and Maintenance Performance: Modular structure design, convenient installation, requiring 10mm space reserved on the terminal side and 30mm space reserved on other sides. It provides free CMT 1000 commissioning and maintenance tools, has event recording function, facilitates fault troubleshooting and system debugging, and reduces maintenance costs.
