ATV71HU55M3S337 Schneider Electric Variable Frequency Drives (VFD)

Out if stock but available for backorder.

Schneider Electric ATV71HU55M3S337 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% of the nominal motor torque for 60 seconds. This model comes with a built-in EMC filter, built-in heatsink, and a coated version for enhanced durability. It operates on a supply voltage of 170-264Vac (200Vac / 220Vac / 230Vac / 240Vac nom.) and has dimensions of H295mm x W175mm x D187mm. The drive is chemically resistant with a conformal coating (reinforced version) and has a degree of protection of IP20 UL type 1. It supports a rated current of 27.5A (230Vac; 4kHz; 3-phase), 17.5A (230Vac; 4kHz; single-phase), with maximum currents of 28.8A (single-phase; for 2s), 45.3A (3-phase; for 2s), and 26.3A (single-phase; for 60s), 413A (3-phase; for 60s). Designed for wall mounting, it uses Modbus and CANopen communication protocols and can operate on single-phase (1P) or 3-phase (3P) networks with an output frequency range of 0.1-599 Hz. The drive includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) programmable (LI1-LI5), 1 digital input programmable as discrete or PTC input (LI6), 1 PWR safety input, 1 digital output (C/O SPDT relay contact) (R1), and 2 digital outputs (NO relay contacts) (R2), along with 1 analog input (-10...+10Vdc) and 1 analog input (0-10Vdc / 0-20mA). Its current consumption is specified as 34.9A (200Vac; 4kW; single-phase), 35A (200Vac; 5.5kW; 3-phase), 29.9A (240Vac; 4kW; single-phase), and 30.8A (240Vac; 5.5kW; 3-phase), with a rated active power of 5.5kW (3-phase) and 4kW (single-phase), equivalent to 7.5HP / 7-1/2HP (3-phase) and 5HP (single-phase).
