ATV71HD18N4S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HD18N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series. It features variable speed/frequency drive capabilities, 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 H400mm x W230mm x D213mm. The degree of protection is IP20 UL type 1. The rated current is 41A (380Vac; 4kHz), 34A (460Vac; 4kHz), with a maximum current of 67.7A for 2 seconds and 61.5A for 60 seconds. It supports wall mounting and uses Modbus and CANopen communication protocols. It is designed for a 3-phase (3P) network with an output frequency of 0.1-599 Hz. It 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 1 PWR safety input, along with 1 digital output (C/O SPDT relay contact) and 2 digital outputs (NO relay contacts). It also features 1 analog input (-10...+10Vdc) and 1 analog input (0-10Vdc / 0-20mA). The current consumption is 45.5A (380Vac) and 37.5A (480Vac), with a rated active power of 18.5kW and rated power of 25HP.
