Schneider Electric ATV61HC11N4D Variable Speed Drive

Schneider Electric ATV61HC11N4D Altivar 61 variable speed drive delivers precise motor control for 3‑phase systems up to 150 HP (110 kW) on 380–480 V mains, with the HC designation indicating a DC choke‑free configuration. This model, part of the Altivar 61 family, uses sensorless vector control to optimize torque and speed across a broad operating range and is commonly applied to pumps, ventilation, conveyors, and other automation tasks. The unit is offered as a heat‑sink‑ready assembly and supports optional communications cards for fieldbus integration (for example CANopen, Modbus, BACnet, CC‑Link, EtherNet/IP, and related interfaces, depending on configuration). Schneider Electric has cataloged ATV61HC11N4D as discontinued for new sales in several regions, with replacement recommendations pointing to ATV630C11N4 for new designs; end‑of‑sales occurred around July 26, 2023, though after‑sales service and spare parts remain available through the product’s end‑of‑life period. This drive continues to be associated with applications requiring robust speed control of industrial motors, including pumping and general ventilation equipment.
