SAN Series Mining Frequency Converter 660V Special for Coal Mines

The Sinoda Mining Frequency Converter SAN Series 660V adopts an AC-DC-AC frequency conversion mode, primarily using IGBT as the main control component, offering high reliability and long service life. This frequency converter features low starting current, high output torque, smooth speed regulation, minimal grid impact, and ease of centralized control. It effectively addresses issues such as heavy-load soft start and stop, and stepless speed regulation of asynchronous motors, achieving energy savings and reducing mechanical equipment wear.

This device is mainly applied in: explosion-proof hoists in coal mines, belt conveyors, scraper conveyors, endless rope winches, underground man-riding vehicles, pump stations, fans, and other equipment for electrical speed control.

Performance:

1. High reliability PLC as the control unit, equipped with various protection functions such as system self-check, temperature alarm, humidity alarm, gas alarm, etc. Supports various communication functions including CAN-OPEN, Modbus, C-net, F-net, Ethernet data transceiving, GPRS, etc.

2. Proprietary DVRC (Dynamic Voltage Rise Control) hardware and software technology, detecting dv/dt, delaying the instantaneous shutdown of IGBT, limiting di/dt and destructive voltage spikes, avoiding motor insulation damage, significantly extending the actual service life of the motor.

3. Multi-motor vector control operation, featuring full vector control to ensure smooth heavy-load, high-torque startup.

4. Excellent harmonic suppression and EMC design with strong capability. Automatically controlled cooling fans, energy-saving and environmentally friendly, ensuring continuous operation of the equipment.

5. Modular structural design, high interchangeability, reducing customer spare parts inventory, easy replacement, and maintenance.

6. User-friendly interface design, facilitating user operation. Supports user-customizable interfaces, allowing display and input of all parameters requiring monitoring within the user interface.
