Description

The Schneider ATV320U07N4C412 is a compact variable speed drive (VSD) from the Altivar Solar series, specifically engineered for solar-powered pump applications. It controls the speed and torque of a three-phase asynchronous or synchronous motor by adjusting the frequency and voltage of the power supply. The drive is designed to operate directly from DC power generated by solar panels, making it ideal for off-grid installations, and can also be configured to switch to an AC grid connection for continuous operation.

Specifications

This VSD is rated for a power output of 0.75 kW (1 HP) and operates on a three-phase voltage range of 380 to 500 V. It has a compact footprint, making it suitable for space-saving installations. The drive features integrated Modbus RTU and CANopen communication protocols and is built to withstand harsh environmental conditions with an IP20 protection rating and coated circuit boards.

Key Features and Benefits

Solar Power Optimization: The drive features an integrated MPPT (Maximum Power Point Tracking) algorithm that maximizes energy extraction from solar panels, ensuring the pump operates at peak efficiency even under varying sunlight conditions.

Dual Power Supply: It offers the flexibility of a dual-supply mode, allowing the drive to connect to both solar panels and an AC grid, ensuring reliable water pumping even on cloudy days or at night.

Motor and Pump Protection: The drive includes a suite of built-in protective functions, such as dry run protection and anti-jam functions, to safeguard the pump and motor, thereby reducing maintenance costs and extending equipment life.

Ease of Use: It features a dedicated “Sun” menu for quick and easy commissioning, simplifying the setup process for solar applications.

Applications

The ATV320U07N4C412 is primarily utilized in solar water pumping systems for a wide range of applications, including:

Agriculture and irrigation systems

Water supply for remote villages and residential areas

Livestock watering in off-grid locations

Water storage tank pumping
