Yaskawa CIMR-P7U4055 AC Variable Frequency Drive

The Yaskawa CIMR-P7U4055 Varispeed P7 AC Drive delivers precise, high-power motor speed and torque control for demanding industrial systems, improving energy efficiency and process stability in large machinery. As part of AC variable frequency drive systems, this 3‑phase PWM inverter with advanced vector control drives AC induction motors from a 380–480 VAC input, offering a ~150 HP class rating and about 134 A of model-rated output current. It provides an output frequency range of 0–400 Hz and is typically mounted in a panel or integrated cabinet within harsh industrial environments. The drive belongs to the Varispeed P7 series and is a Yaskawa Electric Corporation product designed for high-power motor speed and torque control, with motor compatibility limited to AC 3-phase induction motors. Common applications include conveyors, compressors, pumps, heavy-duty processing equipment, material handling systems, large HVAC installations, pump stations, and manufacturing lines seeking energy-efficient operation and tighter process control. Common replacements include Yaskawa CIMR-AU4A0055FAA, CIMR-AC4A0055FAA, and CIMR-G7A4055.
