Description

The Schneider Electric ATV303HU22N4 is a specialized frequency inverter designed for three-phase asynchronous motors. This Altivar 303 series unit manages a power output of 2.2 kW (3 HP) at 400V. It offers a cost-effective solution for machine builders who require reliable performance in a compact footprint.

Advanced Control and Power Management

This drive provides exceptional motor control through optimized voltage-vector algorithms. The internal architecture includes a dedicated 24V DC logic supply for digital inputs. This supply delivers up to 100 mA and features integrated short-circuit protection. Consequently, users can power control circuits directly without adding external transformers.

Furthermore, the device contains a precise 10V DC reference output for speed control. This output supports potentiometers between 2.2 and 10 kOhm. The drive protects this reference signal against overloads to ensure stable frequency setpoints. These built-in power sources significantly simplify the electrical cabinet wiring process.

Versatile Industrial Applications

Industrial facilities typically deploy this drive for simple machine automation tasks. It performs exceptionally well in conveyor systems, packaging equipment, and basic pump applications. Because the drive includes comprehensive thermal protection, it effectively prevents motor damage during heavy start-up cycles. The Modbus connectivity also allows operators to monitor drive health and energy consumption remotely.
