Out if stock but available for backorder.

Schneider Electric ATV71HD18N4Z 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 / 5 points. 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 includes a built-in DC choke, EMC filter, non-detachable display, and built-in heatsink. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nominal) and has dimensions of H400mm x W230mm x D213mm. With an IP20 UL type 1 degree of protection, it supports a rated current of 41A at 380Vac (4kHz), 34A at 460Vac (4kHz), with a maximum current of 67.7A for 2 seconds and 61.5A for 60 seconds. The ATV71HD18N4Z is designed for wall mounting and uses Modbus and CANopen communication protocols. It is suitable for a 3-phase network with an output frequency range of 0.1-599 Hz. The drive offers 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) plus 1 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 includes 1 analog input (-10...+10Vdc) and 1 analog input (0-10Vdc / 0-20mA), with a current consumption of 45.5A at 380Vac and 37.5A at 480Vac. The rated active power is 18.5kW, and the rated power is 25HP.
