Delta VFD007M21A 1 HP 0.75 kW 230 V Single-Phase VFD-M Sensorless Vector Micro AC Drive

The Delta VFD007M21A is a compact VFD-M series variable frequency drive designed for reliable speed control of small AC motors. With a 1 HP (0.75 kW) motor capacity and single-phase 200–240 V input, it is well suited for compact industrial machinery, conveyors, fans, pumps, production equipment, and other motor-driven applications requiring adjustable speed control. The drive provides a rated output current of 5.0 A and approximately 1.9 kVA output capacity.

A key feature of the VFD007M21A is its sensorless vector control technology, which provides improved motor-control performance compared with basic V/F operation. The drive supports an output frequency range of 0.1–400 Hz and includes functions such as DC injection braking, dynamic braking, adjustable acceleration and deceleration, and built-in keypad operation. These features allow the drive to be configured for different speed-control and stopping requirements.

The VFD007M21A uses a compact IP20 enclosure and measures approximately 85 × 141.5 × 113 mm, making it practical for installation inside industrial control panels. The model is a legacy/discontinued Delta drive, so the exact VFD007M21A remains relevant for equipment maintenance, replacement, and retrofit applications where matching the original model is important.
