Saftronics CIMR-G3U4015 Variable Frequency Drive

The Saftronics CIMR-G3U4015 is a 20 HP, 40 A, three‑phase AC drive (VFD) that provides precise variable‑speed control for industrial motors. It accepts 380–460 VAC input at 50/60 Hz and delivers a 0–460 VAC, three‑phase output with a programmable frequency range up to 0–400 Hz, enabling fine‑tuned speed adjustments across a broad operating envelope. This model is identified by CIMR-G3U4015 (often listed as CIMRG3U4015) and weighs about 48 pounds. The CIMR-G3U4015 is part of Saftronics' G3 series of adjustable‑frequency AC drives and is noted as discontinued by the manufacturer, making availability of spare parts and direct support a consideration for procurement. Typical applications for this class of drive include direct control of 3‑phase motors in machinery where variable speed is required, such as fans, pumps, and conveyors, helping to optimize process control, energy use, and motor protection. When selecting a replacement or upgrade, verify compatibility with your motor’s voltage and current ratings, the required control interfaces, and your system’s harmonic and protection requirements to ensure reliable operation with your existing electrical infrastructure.
