ATV71HD11N4S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HD11N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series. It features variable speed/frequency drive functionality with U/F ratio (2 points / 5 points), sensorless flux vector control, ENA System, and vector control with or without speed feedback. It can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. The design includes a built-in DC choke, EMC filter, heatsink, and a coated version for enhanced chemical resistance. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.) and has dimensions of H295mm x W210mm x D213mm. The ATV71HD11N4S337 offers an IP20 UL type 1 degree of protection and supports wall mounting. It has a rated current of 27.7A (380Vac; 4kHz), 21A (460Vac; 4kHz), with a maximum current of 45.7A for 2 seconds and 41.6A for 60 seconds. Communication is facilitated through Modbus and CANopen protocols, and it is designed for a 3-phase (3P) network with an output frequency range of 0.1-599 Hz. The unit includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) programmable, 1 digital input programmable as discrete or PTC input, 1 PWR safety input, 1 digital output (C/O SPDT relay contact), 2 digital outputs (NO relay contacts), and 2 analog inputs. It has a current consumption of 36.6A (380Vac) and 30A (480Vac), with a rated active power of 11kW and rated power of 15HP.
