Delta VFD015E21A 2 HP 1.5 kW 230 V Single-Phase VFD-E Sensorless Vector AC Drive

The Delta VFD015E21A is a VFD-E series AC drive designed for reliable variable-speed control of small industrial motors. With a 1.5 kW (2 HP) motor capacity and single-phase 200–240 V AC input, it is suitable for compact machinery, conveyors, pumps, fans, machine tools, material-handling equipment, and other motor-driven applications. Its 7.5 A rated output provides appropriate capacity for 2 HP constant-torque applications.

The VFD015E21A provides flexible motor-control capabilities through V/F and sensorless vector control. It supports an output frequency range of 0.1–600 Hz and includes built-in PLC functionality, PID control, Modbus communication via RS-485, DC injection braking, and dynamic braking. The VFD-E platform also supports optional communication and expansion modules, providing additional flexibility for automation-system integration.

The drive uses an IP20 enclosure and Frame B construction, with natural cooling and a compact design suitable for control-panel installation. The VFD015E21A is an obsolete/discontinued model, so the exact part number can be particularly relevant for maintenance, replacement, and retrofit applications where matching the existing drive is important.
