Product Introduction
The modular multi-circuit VFD is an integrated product developed for specific application scenarios with a rated voltage of 1140V. The 2-in-1 combination product covers the power range of 110kW~400kW, while the 3-in-1 combination product covers 400kW~710kW. It can be used in underground coal mine multi-drive belt conveyors, armored face conveyors, emulsion pumps and other applications.
Triple combination inverter
Technical Characteristics
Modular structure
the VFD module can be pulled out as a single unit for complete replacement and fast maintenance;
Fast connection to power supply and loads
The main circuit uses flame-proof quick-connect terminals for fast connection to power supply and loads;
Water cooling
both internal or external circulation cooling water can be used, for flexible and versatile deployment;
Low parasitic inductance with laminated bus design
Low parasitic inductance with laminated bus design, long service life, low interference and reliable operation;
Advanced master-slave load-sharing function based on communication
Advanced master-slave load-sharing function based on communication, long-term reliable multiple-device operation, high balancing accuracy, short commissioning cycle;
Improve reliability and response time
The load-sharing communication cable is connected internally to improve reliability and response time;
The optional speed control function
The optional speed control function enables real-time speed control depending on the amount of materials on the conveyor; energy-saving and cost-reducing;
The three-level topology
The three-level topology provides a perfect output waveform, low dv/dt, and worry-free motor operation.
The long-distance power transmission technology
The long-distance power transmission technology allows the distance from the inverter to the motor to be up to 1500m;
Optimized EMC design
Optoelectronic isolation at input and output; good anti-interference capability and low failure rate;
No need to configure any external equipment
Optimized EMC design for low grid impact;
long service life
Self-healing film capacitors
Convenient and flexible
Easy-to-use operation and control interface
Silent operation
