Schneider Electric ATV320U11N4C Frequency Converter

Schneider Electric ATV320U11N4C is a 1.1 kW Altivar Machine frequency converter designed for 380–500 VAC three‑phase motors in a compact IP20 enclosure. This 3‑phase drive belongs to the ATV320 family and provides reliable variable‑speed control for small machines and automation tasks such as conveyors, pumps, and fans. It delivers a 0.1–599 Hz output frequency range and uses voltage/frequency (U/F) control with energy‑saving optimization described in the datasheet. The switching frequency is adjustable from 2 to 16 kHz (rated value 4 kHz), enabling a balance between control responsiveness and noise across diverse loads. The unit includes built‑in safety functions and EMC/IEC compliance appropriate for indoor panel installations, combining compact dimensions with dependable performance in industrial environments. As part of Schneider Electric’s Altivar Machine platform, it integrates with other automation equipment to simplify installation and coordination within machine control systems.
