 Power range from 25KW to 220KW series: VFD-B, VFD-M, the VFD-E, VFD-EL, VFD-L and the VFD-VE, VFD-S and other series. Provide a variety of load applications. The full range of inverter are high-speed processor, with self-developed sensorless vector control technology, can easily achieve high starting torque and smooth operation. In addition, the VFD full range of inverters by UL / CE certification, in line with global market demand, an advanced design and the latest power electronics technology, automated large-scale production, strict and timely quality control system, the best quality and the most competitive prices. Meet the needs of customers with the best control. Delta VFD series is not only focus on quality more perfect pre-sales and after-sales service, sales service system throughout the world to meet your needs, and the other with Delta PLC and HMI to do systems integration control, you are engaged in the best choice for the FA industry. This series elasticity module design, the biggest feature is the built-in PLC function, you can write a simple program storage and execution; can plus a special function expansion card and communication card is the best representative of Delta's low-power inverter to meet the industry's most diverse needs. 
 Features of this series easy to operate, said, provide a practical function keys, the use of high-frequency switching technology makes the motor running noise dropped significantly; highly cost. Product specifications output frequency of 1.0 - 400Hz can set the V / F claims Curve carrier frequency up to 10kHz embedded PID feedback control, international communication format for communication (RS - 485 interface, baud rate up to 38400bps) Built-in instant blackout and fault restart feature built-in sleep / wake function to support the communication interface module: kidney disease - 02 protein - 01 Parkinson's disease - 01 Application Example Building, air conditioning, building water supply systems within the watershed system, medium and large oven temperature control , ribbon machine (shoelaces, backpack), packaging machines, conveyors, dryers of windmills
