Product details

Overview

The ATV32H055N4437 is a Schneider Altivar 32 variable speed drive rated at 550 W output power on a 500 V supply, delivering 1.9 A output current. It supports CANopen and Modbus protocols via an RJ45 connector, includes an integrated Class C2 EMC filter, and is rated IP20 for cabinet mounting.

Applications

As an Altivar 32 drive, it provides variable-speed control for three-phase asynchronous motors in applications such as conveyors, pumps, fans, and packaging machinery.

The drive communicates via CANopen and Modbus, enabling integration into distributed automation networks without additional gateways. An adjustable PID regulator allows closed-loop process control for pressure, flow, or level regulation directly from the drive. Built-in protections include input phase loss, output phase-to-earth overcurrent, overheating, motor short-circuit, and thermal overload, reducing the need for external motor protection relays.
