About ATV12HU30M3 Schneider VFD

Description

This Altivar 12 variable speed drive can feed 3-phase asynchronous motors in supply line connection. It works at a rated power up to 3kW / 4hp and a rated voltage from 200V to 240V AC. It is designed with heatsink for normal environments and fan-cooled enclosure. Transient overtorque function prevents stoppages by unjamming the machine with extra torque, when needed, this reduces downtime and maintenance costs. It features underload and overload detection, this contribute to protect your installation. The Altivar 12 drive integrates as standard the Modbus communication protocol, which can be accessed via the RJ45 connector located on the underside of the drive. It is designed for simple industry and commercial machines and appliances, such as conveyors, pumps, extractors, access barriers and treadmills. SoMove software compatibility enables saving and transfering of configurations to spare drive, reducing maintenance downtime. It features an optimized application of power and torque for ventilation and pumping applications, this allows up to 30% energy savings.
