Schneider Electric ATV930U40N4 Variable Speed Drive

The Schneider Electric ATV930U40N4 Altivar Process 930 series variable frequency drive (VFD) delivers precise speed and torque control for three‑phase motors in industrial process applications. This 4 kW (5 HP) drive operates on 380–480 V AC three‑phase power with a 50–60 Hz input (±5%), providing an output current of approximately 9.3 A to a three‑phase motor. It supports vector control and V/F control, and includes a built‑in braking chopper for dynamic braking as needed. Communication options cover Modbus TCP, Ethernet/IP, and Modbus serial, with dual RJ45 Ethernet ports for reliable network integration. An integrated EMC filter (C2/C3 category) helps meet electrical noise requirements, and the unit is housed in an IP21 enclosure suitable for panel or wall mounting. The operating temperature range is −15°C to +60°C, making it suitable for demanding industrial environments. Typical applications include water and wastewater treatment, oil and gas processing, mining, food and beverage production lines, pump and fan systems, conveyors, compressors, and other heavy process machinery requiring reliable variable speed motor control and energy efficiency.
