Out if stock but available for backorder.

Schneider Electric ATV71HD22N4S337 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 or 5 points. It features sensorless flux vector control, ENA System, and vector control with or without speed feedback. This model can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. It includes a built-in DC choke, EMC filter, and a heatsink, with a coated version for enhanced chemical resistance. The supply voltage ranges from 323-528Vac, accommodating 380Vac, 400Vac, 480Vac, and 500Vac nominal values. Its dimensions are H420mm x W240mm x D236mm, and it offers an IP20 UL type 1 degree of protection. The rated current is 48A at 380Vac (4kHz), 40A at 460Vac (4kHz), with a maximum current of 79.2A for 2 seconds and 72A for 60 seconds. For installation, it supports wall mounting and communicates via Modbus and CANopen protocols. It operates on a 3-phase network with an output frequency range of 0.1-599 Hz. The device includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source), an additional programmable digital input, and a PWR safety input, along with 3 digital outputs. It also features 2 analog inputs for comprehensive control. The current consumption is 50A at 380Vac and 42A at 480Vac, with a rated active power of 22kW and a rated power of 30HP.
