The Delta VFD015E43A is a VFD-E series AC drive designed for dependable variable-speed control of three-phase AC motors. With a 1.5 kW (2 HP) motor capacity and 380–480 V three-phase input, it is suitable for industrial machinery, conveyors, pumps, fans, material-handling equipment, and other constant-torque applications. Its 4.2 A rated output current provides appropriate capacity for 2 HP motor applications.
The VFD015E43A combines V/F control with open-loop sensorless vector control to provide flexible motor-control performance. It supports an output frequency range of 0.1–600 Hz and includes DC injection and dynamic braking functions. The VFD-E platform also supports RS-485 communication and optional expansion cards for additional I/O and industrial communication capabilities, providing flexibility when integrating the drive into automation systems.
The drive uses an IP20 enclosure and Frame A construction, with natural cooling for this 1.5 kW model. Its compact design makes it practical for control-panel installation where space is limited. The VFD015E43A is an obsolete model that is no longer manufactured, making the exact part number particularly relevant for maintenance, replacement, and retrofit applications where equipment compatibility is important.
