About this item
The Altivar 21 is Schneider Electric's adjustable-speed AC drive family for three-phase asynchronous motors on variable-torque loads — the fans and pumps that dominate HVAC and building-services work. Sold under Schneider's Telemecanique brand, the ATV21HU22N4 is rated 2.2 kW (3 HP) from a 380–480 V three-phase supply and delivers 5.1 A of continuous output across a 0.5–200 Hz frequency range. Control choices run from energy-saving and V/Hz modes to sensorless flux vector, with Modbus built in over RS-485 and option cards available for BACnet, LonWorks, METASYS N2, and APOGEE FLN building networks.
This listing is for the drive unit itself: a Japan-built ATV21HU22N4 in the compact IP20 open-style frame with an integrated Class A EMC filter, exactly as photographed. It ships in the manufacturer's box with the owner's manual and mounting bracket included, and suits maintenance spares or a like-for-like replacement for Altivar 21 drives already in service, with no re-engineering around a newer platform.
Condition: Used, tested, as listed, with some cosmetic blemishes on the unit. The photographs are of the actual unit you'll receive, covered by our warranty.
