ATV71HD18M3X337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HD18M3X337 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 or 5 points. It features sensorless flux vector control, ENA System, and vector control with or without speed feedback. This model can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. It has a built-in heatsink, coated version for enhanced durability, and operates on a supply voltage of 170-264Vac (200Vac / 220Vac / 230Vac / 240Vac nom.). The dimensions are H420mm x W240mm x D236mm, with chemical resistance provided by a conformal coating (reinforced version). It offers a degree of protection of IP20, IP21, and UL type 1, with a rated current of 75A (230Vac; 2.5kHz) and a maximum current of 124A for 2 seconds and 112A for 60 seconds. Wall mounting is supported, and it uses Modbus and CANopen communication protocols. Designed for a 3-phase (3P) network with an output frequency range 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 another for PWR safety, and 3 digital outputs. It also features 2 analog inputs for versatile connectivity. The current consumption is 77A at 200Vac and 69A at 240Vac, with a rated active power of 18.5kW and rated power of 25HP.
