Schneider Electric ATV21HU15M3X Variable Speed Drive

Schneider Electric ATV21HU15M3X is a 1.5 kW (2 HP) Altivar 21 variable-speed drive designed for 200–240 V three-phase mains and indoor panel mounting. It accepts 3-phase input in the 200–240 VAC range and provides motor speed control across a 0.5 Hz to 200 Hz output, with a compact IP20 enclosure suitable for dry indoor environments. The HU15M3X designation places this unit in Schneider’s ATV21 family and makes it a practical choice for small asynchronous motors in pumps, fans, and light conveyors, delivering smoother starts, adjustable speed, and energy‑saving operation. With a compact form factor and simple setup for 50/60 Hz service, this drive is aimed at cost-effective speed control in space‑constrained automation layouts and is typically installed in indoor control panels, where IP20 protection helps safeguard the electronics.
