ATV71HU40M3S337 Schneider Electric Variable Frequency Drives (VFD)

Schneider Electric ATV71HU40M3S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series. It features variable speed/frequency drive capabilities with U/F ratio adjustment (2 points / 5 points), sensorless flux vector control, ENA System, and vector control with or without speed feedback. It can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. The design includes a built-in EMC filter, a 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 H260mm x W155mm x D187mm. The part offers chemical resistance with a conformal coating (reinforced version) and has a degree of protection of IP20 UL type 1. The rated current is 17.5A (230Vac; 4kHz; 3-phase), 13.7A (230Vac; 4kHz; single-phase), with maximum currents of 22.6A (single-phase; for 2s), 28.8A (3-phase; for 2s), 20.6A (single-phase; for 60s), and 26.3A (3-phase; for 60s). It supports wall mounting and uses Modbus and CANopen communication protocols. It is compatible with both single-phase (1P) and 3-phase (3P) networks, with an output network frequency of 0.1-599 Hz. The device 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). It also features 1 analog input (-10...+10Vdc) and 1 analog input (0-10Vdc / 0-20mA). The current consumption is specified as 25.9A (200Vac; 3kW; single-phase), 25.8A (200Vac; 4kW; 3-phase), 22A (240Vac; 3kW; single-phase), and 22.9A (240Vac; 4kW; 3-phase), with rated active power of 4kW (3-phase) and 3kW (single-phase), and a rated power of 5HP (3-phase).
