Delta Electronics — Variable Frequency Drives
The Delta VFD-B EL Series is a general-purpose sensorless vector AC drive designed for speed and torque control of three-phase induction motors. It features built-in EMC filters (Class A/B) for compliance with European EMC directives without external filtering. The drive supports multiple control modes including V/f, sensorless vector, and torque control, with automatic torque boost for optimal starting performance. An integrated PID controller, PLC function with 100-step capacity, and MODBUS RTU communication enable standalone process control applications.
