ATV71HU40N4S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HU40N4S337 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 (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.) and has dimensions of H260mm x W155mm x D187mm. The degree of protection is IP20 UL type 1, with a rated current of 10.5A (380Vac; 4kHz), 7.6A (460Vac; 4kHz), 17.3A max. current (for 2s), and 15.8A max. current (for 60s). 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 x analog output (0-10Vdc / 0-20mA), 5 x digital inputs (24Vdc; sink/source) plus 1 additional digital input programmable as discrete or PTC input, and 1 x digital output (C/O SPDT relay contact) plus 2 x digital outputs (NO relay contacts). It also features 1 x analog input (-10...+10Vdc) and 1 x analog input (0-10Vdc / 0-20mA), with a current consumption of 14.1A (380Vac) and 11.5A (480Vac). The rated active power is 4kW, and the rated power is 5HP.
