The Schneider Electric ATV930U55M3 is a 5.5 kW variable frequency drive designed for three-phase 200 to 240 VAC industrial motor control systems. It belongs to the Altivar Process ATV900 range and is intended for demanding applications requiring reliable speed regulation, process control, braking capability, and industrial communication.
In Normal Duty operation, the drive supports motors up to 5.5 kW with a continuous output current of 25.4 A at 4 kHz. For Heavy Duty operation, it supports motors up to 4.0 kW with a continuous output current of 18.7 A. This dual rating allows the drive to be selected according to the load profile, such as variable torque pump and fan duty or constant torque conveyor and machinery duty.
The ATV930U55M3 includes an integrated braking unit for applications requiring controlled deceleration. It supports output frequencies up to 599 Hz and adjustable switching frequencies from 2 to 16 kHz, providing flexible operation for asynchronous motors, permanent magnet motors, and synchronous reluctance motors.
Built-in Ethernet/IP, Modbus TCP, and Modbus serial communication make the drive suitable for networked automation systems. Optional interface cards can extend connectivity to PROFIBUS DP, PROFINET, EtherCAT, DeviceNet, CANopen, and other industrial networks.
With Safe Torque Off rated to SIL 3, integrated diagnostics, forced-air cooling, and IP21 protection, this drive is suitable for industrial process equipment, conveyors, pumps, fans, mixers, compressors, and packaging machinery.
