The Schneider Altivar ATV320U75M3C412 is a compact variable speed drive (VSD) from the Altivar Solar series.It is designed for efficient and reliable operation of solar water pumping systems.The drive has a rated power of 7.5 kW and operates on a three-phase voltage supply of 200 to 240V.
Key Features and Benefits
This drive is engineered to maximize the efficiency of solar-powered pump applications. Its primary feature is Maximum Power Point Tracking (MPPT), an algorithm that continuously monitors the solar panels’ output and adjusts the motor’s speed to utilize the maximum available power. This ensures the pump delivers the highest possible water flow throughout the day, even with fluctuating sunlight.
The drive is built in a compact, book-style form factor to save space in control cabinets and features an integrated C2 EMC filter to reduce electromagnetic interference.It includes a range of integrated safety functions, such as Safe Torque Off (STO), which prevents unexpected motor startup.It also has built-in pump-specific protection features like dry-run protection, which automatically shuts off the pump when the water source is depleted, preventing damage.The drive can also be configured to operate on a dual power supply, using either a solar array or a conventional AC grid for continuous operation.
Primary Applications
The Schneider Altivar ATV320U75M3C412 is a robust solution for a variety of medium to large-scale solar pumping needs, particularly in remote or off-grid areas. Its main applications include:
Agricultural Irrigation: Providing water for farms and large greenhouses.
Community Water Supply: Supplying water to villages and rural communities.
Water Transfer and Distribution: Pumping water for filling large tanks, reservoirs, and water distribution networks.
Livestock Watering: Ensuring a reliable and consistent water supply for large herds in remote pastures.
