Schneider ATV320U75N4C412 | Variable speed drive, Altivar Solar, 7.5kW, 380 to 500V, 3 phases, compact

Description

The Schneider ATV320U75N4C412 is a compact variable speed drive (VSD) from the Altivar Solar series, engineered to optimize the performance of solar-powered pump systems. It efficiently controls the speed and torque of a 3-phase asynchronous or synchronous motor by converting DC power from solar panels into a variable-frequency AC output. This drive is a key component for off-grid water pumping, ensuring maximum efficiency and reliability.

Specifications

This VSD is rated for a power output of 7.5 kW (10 HP) and is compatible with a three-phase supply voltage ranging from 380 to 500 V. It features a compact, wall-mounted design with an IP20 protection rating. The drive includes integrated Modbus RTU and CANopen communication protocols, allowing for seamless integration and control within a larger automation system. It also has a built-in Class C2 EMC filter.

Key Features and Benefits

Solar Optimization: The drive incorporates a dedicated MPPT (Maximum Power Point Tracking) algorithm to harvest the maximum possible energy from the solar array, ensuring the pump operates at peak efficiency even during periods of low sunlight.

Dual Power Source: It supports a dual-supply mode, allowing it to switch between solar power and an AC grid connection. This feature guarantees continuous pump operation during cloudy days or at night.

Pump and Motor Protection: The VSD provides essential protective functions, including dry run protection, pump overload, and anti-jam features, which safeguard the pump and motor from damage, thus extending their lifespan and reducing maintenance costs.

Robust and Reliable: Built with coated circuit boards, the drive is designed to withstand harsh environments and can operate in a wide temperature range, ensuring long-term reliability.

Applications

The ATV320U75N4C412 is primarily used in solar water pumping systems for a variety of applications, including:

Agricultural and irrigation systems

Water supply for remote residential areas and villages

Livestock watering in off-grid locations

Water storage tank pumping
