ATV71HC28N4D Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HC28N4D is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series designed for variable speed and frequency control. 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% for 60 seconds. This model comes with a built-in EMC filter, a built-in heatsink, and a coated version without a DC choke. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.) and has dimensions of H1190mm x W595mm x D377mm. The ATV71HC28N4D offers chemical resistance with a conformal coating (reinforced version) and has an IP30 UL type 1 degree of protection. It supports a rated current of 550A (380Vac; 2.5kHz), 550A (460Vac; 2.5kHz), with a maximum current of 907A for 2 seconds and 825A for 60 seconds. Wall mounting is the prescribed mounting mode. Communication is facilitated via Modbus and CANopen protocols, and it is designed for a 3-phase (3P) network with an output frequency range of 0.1-500 Hz. The unit includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) plus 1 additional digital input programmable as discrete or PTC input and another for PWR safety, along with 3 digital outputs. It also features 2 analog inputs for comprehensive control. The current consumption is rated at 494A (380Vac) and 396A (480Vac), with a rated active power of 280kW and a rated power of 450HP.
