Schneider Electric ATV21W075N4 AC Speed Drive

Schneider Electric's ATV21W075N4 Altivar 21 AC speed drive is a compact, IP54-rated variable-frequency drive that delivers 0.75 kW (1 hp) to a three-phase induction motor when powered from a 380–480 V supply. It ships with an integrated heat sink and an EMC filter Class A, enabling compliant operation in demanding environments without additional accessories. This model is part of the Altivar 21 family and supports three-phase inputs in the 380–480 V range, with typical line currents around 1.7 A at 380 V and 1.4 A at 480 V. Motor control options include constant-voltage/frequency (V/f) with automatic IR compensation and current vector control (FVC) without speed feedback, offering flexible performance for simple drive tasks and improved energy efficiency. Designed for small to mid-size applications, it targets asynchronous motor control in industrial settings where compact size, rugged IP54 enclosure, and straightforward setup are priorities.
