Delta Electronics — Variable Frequency Drives
The Delta VFD-BL series is a heavy-duty AC drive designed for applications requiring high overload capacity and reliable performance in demanding industrial environments. It provides sensorless vector control with 150% overload for 60 seconds and built-in brake chopper for rapid deceleration. The drive supports multiple control modes including V/F, sensorless vector, and closed-loop vector with optional encoder feedback card. Its extensive fieldbus options including PROFIBUS-DP, DeviceNet, CANopen, and EtherNet/IP make it suitable for integration into multi-vendor automation networks. The pluggable control terminals and removable fan assembly simplify installation and maintenance.
