Out if stock but available for backorder.

Schneider Electric ATV71HD55N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series designed for variable speed and frequency control. It features sensorless flux vector control, ENA System Vector control with or without speed feedback, and can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. This model comes with a built-in DC choke, EMC filter, and a heatsink coated version for enhanced durability. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.), with dimensions of H630mm x W320mm x D290mm. The drive has a conformal coating for chemical resistance, an IP20 UL type 1 degree of protection, and supports wall mounting. It offers a rated current of 116A (380Vac; 2.5kHz), 96A (460Vac; 2.5kHz), with a maximum current of 191A for 2 seconds and 174A for 60 seconds. Communication is facilitated through Modbus and CANopen protocols, and it is designed for a 3-phase network with an output frequency range of 0.1-500 Hz. The drive includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source), 1 additional digital input programmable as discrete or PTC input, 1 safety input, and 3 digital outputs. It also features 2 analog inputs for comprehensive control and monitoring. The rated active power is 55kW, with a rated power of 75HP.
