Schneider Electric ATV32H055N4 Variable Speed Drive

Schneider Electric ATV32H055N4 is a 0.55 kW Altivar 32 variable speed drive with an integrated heat sink for reliable three‑phase motor control on 380–500 V systems. It supports both asynchronous and synchronous motors in open‑loop mode with a speed range of 1 to 100 for asynchronous operation, delivering precise torque and speed control in demanding automation tasks. The drive accepts 323–550 V, 50/60 Hz input and provides a nominal output current of 1.9 A (2.8 A at 380 V, 2.2 A at 500 V) with a maximum transient current of 2.9 A for short peaks, while the output frequency spans 0.5 Hz to 599 Hz (0.0005–0.599 kHz). It features a nominal switching frequency of 4 kHz, adjustable from 2 to 16 kHz to balance speed response and electrical noise. An integrated Class C2 EMC filter helps meet common industrial EMI requirements, and a front RJ45 port supports Modbus and CANopen communications. Physical dimensions are 45 mm wide, 325 mm high, and 245 mm deep, with a net weight around 2.5 kg. The ATV32H055N4 aligns with standards including EN 61800‑3 (environments 1 and 2, category C2) and EN 55011 (Class A), and is designed to protect against phase faults, short circuits, overheating, and motor‑phase faults. Typical applications include conveyors, pumps, fans, and other medium‑power automation tasks where energy‑efficient speed control and robust motor protection are required.
