ATV71HD55N4383 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HD55N4383 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series designed for synchronous motor control. It features a U/F ratio with options for 2 points or 5 points, 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 heatsink. The supply voltage ranges from 323-528Vac, accommodating 380Vac, 400Vac, 480Vac, and 500Vac nominal values. Dimensions are H630mm x W320mm x D290mm, with a degree of protection rated at IP20, IP21, and UL type 1. The rated current is 116A at 380Vac and 2.5kHz, 96A at 460Vac and 2.5kHz, with a maximum current of 191A for 2 seconds and 174A for 60 seconds. It supports wall mounting and uses Modbus and CANopen communication protocols. Designed for a 3-phase network with an output frequency range of 0.1-500 Hz, it includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source), an additional programmable digital input, and a PWR safety input. There are also 1 digital output (C/O SPDT relay contact) and 2 digital outputs (NO relay contacts), alongside 2 analog inputs for comprehensive connectivity. The current consumption is 120A at 380Vac and 101A at 480Vac, with a rated active power of 55kW and a rated power of 75HP.
