1. SCR trigger closed-loop control algorithm
SCR closed-loop control function, designed for standard and heavy loads. The user can select current-limiting start and voltage ramp start according to the load condition to achieve smooth torque-free oscillating start effect.
2. High control precision
Real-time use of Cortex-M332-bit core CPU to perform central control, with fast speed, high precision and strong anti-interference ability.
3. Beautiful appearance
The patent-protected main circuit has a three-in-six-out structure and a built-in current transformer, which is convenient for wiring and high reliability.
4. Standard MODBUS-RTU protocol
When ordering, the user can choose the standard MODBUS-RTU communication protocol or not according to the needs of the site.
5. Integrated advanced protection features
It has protection functions such as input and output phase loss, overload, overcurrent, phase current imbalance, thyristor overtemperature, etc., to protect the motor and related equipment.
6. Fireproof material
Below 90KW is a full plastic shell structure, which is made of flame-retardant ABS material. The upper cover of the power section of 90KW and above is a plastic shell structure, and the main frame is made of aluminum-zinc plate material, which has heat resistance and corrosion resistance.
7. Movable panel
The panel can be moved to equipment operating surface through machine interface for remote control, which is convenient for on-site use.
8. Easy maintenance
The monitoring signal coding system composed of 4-digit digital display monitors the working conditions of the system equipment 24 hours a day, and provides fast fault diagnosis at the same time.
