ATV71HU22M3S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HU22M3S337 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. This model can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. It includes a built-in EMC filter, built-in heatsink, and is a coated version for enhanced durability. The supply voltage ranges from 170-264Vac, accommodating 200Vac, 220Vac, 230Vac, and 240Vac nominal values. Dimensions are H260mm x W155mm x D187mm, with a conformal coating for chemical resistance. It has an IP20 UL type 1 degree of protection and supports wall mounting. The rated current specifications are 11A for 230Vac at 4kHz in a 3-phase configuration, 8A for 230Vac at 4kHz in a single-phase configuration, with maximum currents of 13.2A (single-phase for 2s), 18.1A (3-phase for 2s), 12A (single-phase for 60s), and 16.5A (3-phase for 60s). Communication is facilitated via Modbus and CANopen protocols, suitable for single-phase (1P) and 3-phase (3P) networks with an output frequency range of 0.1-599 Hz. It features 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source), an additional programmable digital input, and a PWR safety input, alongside 1 digital output (C/O SPDT relay contact) and 2 digital outputs (NO relay contacts). Analog inputs include 1 x (-10...+10Vdc) and 1 x (0-10Vdc / 0-20mA). Current consumption is detailed for various configurations, with rated active power of 2.2kW for 3-phase and 1.5kW for single-phase, corresponding to 3HP and 2HP respectively.
