Description
Schneider ATV320U04M2C412 | Variable speed drive, Altivar Solar, 0.37kW, 200 to 240V, 1 phase, compact

The Schneider Altivar ATV320U04M2C412 is a compact variable speed drive (VSD) specifically for solar pump applications with a low power rating. It’s designed to operate on a single-phase voltage supply from 200 to 240V and has a rated power of 0.37 kW.
Key Features and Benefits
This VSD is optimized for efficiency and reliability in off-grid and remote settings. It includes Maximum Power Point Tracking (MPPT), a key feature that continuously adjusts the motor speed to match the available power from the solar panels, ensuring the pump operates at maximum efficiency. This is crucial for maximizing water output throughout the day, especially in changing weather conditions.
The drive’s compact, book-style form factor is ideal for saving space in control cabinets. It has a high-quality integrated C2 EMC filter to reduce electromagnetic interference, which is important for sensitive electronic equipment. For safety, it includes built-in functions like Safe Torque Off (STO) to prevent accidental motor startup. It also has specific protections for pumping applications, such as dry-run protection to prevent damage when the water source is depleted.
Primary Applications
The ATV320U04M2C412 is well-suited for smaller-scale solar water pumping systems where a single-phase power supply is required. Its primary applications include:
Small-scale agricultural irrigation such as watering small plots or greenhouses.
Residential and rural water supply for homes or small farms.
Livestock watering in remote areas without a reliable power grid.
