ATV71HU22N4S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HU22N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series, designed for variable speed and frequency control with a U/F ratio of 2 points / 5 points. It features sensorless flux vector control, ENA System, and vector control with or without speed feedback, capable of delivering 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. This model includes a built-in DC choke, EMC filter, and a heatsink with a coated version for enhanced durability. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.), with dimensions of H230mm x W130mm x D175mm. The device offers chemical resistance through a conformal coating (reinforced version) and has an IP20 UL type 1 degree of protection. Rated current specifications include 5.8A (380Vac; 4kHz), 4.8A (460Vac; 4kHz), with a maximum current of 9.6A for 2 seconds and 8.7A 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 range of 0.1-599 Hz, it includes 1 x analog output (0-10Vdc / 0-20mA), 5 x digital inputs (24Vdc; sink/source), 1 x digital input (24Vdc; sink/source) programmable as discrete or PTC input, 1 x digital input (24Vdc) for PWR safety, and 3 x digital outputs. Additionally, it has 2 x analog inputs for versatile connectivity. The current consumption is rated at 8.2A (380Vac) and 7.1A (480Vac), with a rated active power of 2.2kW and a rated power of 3HP.
