ATV71HU55N4S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HU55N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series. It features variable speed/frequency drive capabilities with U/F ratio adjustment (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.), with dimensions of H295mm x W175mm x D187mm. The degree of protection is IP20 UL type 1, with a rated current of 14.3A (380Vac; 4kHz), 11A (460Vac; 4kHz), and a maximum current of 23.6A for 2 seconds and 21.5A for 60 seconds. It supports wall mounting and uses Modbus and CANopen communication protocols. Designed for a 3-phase (3P) network with an output frequency of 0.1-599 Hz, it includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source), 1 digital input (24Vdc; sink/source) programmable as discrete or PTC input, 1 digital input (24Vdc) for PWR safety, and 3 digital outputs. It also features 2 analog inputs for versatile connectivity. The current consumption is 20.3A (380Vac) and 17A (480Vac), with a rated active power of 5.5kW and rated power of 7.5HP / 7-1/2HP.
