Schneider Electric ATV61HU55N4 Variable Frequency Drive

Schneider Electric's Altivar 61 ATV61HU55N4 is a 5.5 kW (7.5 HP) three-phase variable-frequency drive designed for 380–480 V AC systems and 50/60 Hz power supplies. It provides precise motor speed control from 0.1 Hz up to 599 Hz, enabling fine-adjustment of general-purpose three-phase motors in industrial settings. The drive includes CANopen and Modbus communications for easy integration into automation networks, and the configuration can be done on-device with a Schneider Graphic Terminal; some configurations also ship with an integrated EMC filter. The unit is housed in an IP20 enclosure, and at 480 V it draws about 14.3 A, with higher current at lower line voltages. This ATV61HU55N4 model is part of the Altivar 61 family, aimed at compact, reliable motor control for tasks such as pumping, fan and conveyor applications in manufacturing and process environments.
