Out if stock but available for backorder.

Schneider Electric ATV71HD37M3X337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series. It features sensorless flux vector control, ENA System Vector control with or without speed feedback, and can deliver 220% of the nominal motor torque for 2 seconds and 170% for 60 seconds. This model comes with a built-in heatsink in a coated version, operates on a supply voltage of 170-264Vac (200Vac / 220Vac / 230Vac / 240Vac nom.), and has dimensions of H550mm x W320mm x D266mm. It offers chemical resistance with a conformal coating (reinforced version) and has a degree of protection rated at IP20, IP21, and UL type 1. The rated current is 144A (230Vac; 2.5kHz) with a maximum current of 238A for 2 seconds and 216A for 60 seconds. Designed for wall mounting, it supports Modbus and CANopen communication protocols, operates on a 3-phase network, and has an output frequency range of 0.1-599 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 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), with a current consumption of 141A at 200Vac and 127A at 240Vac. The rated active power is 37kW, and the rated power is 50HP.
