Description
Schneider ATV320U15N4C412 | Variable speed drive, Altivar Solar, 1.5kW, 380 to 500V, 3 phases, compact
description
The Schneider ATV320U15N4C412 is a compact variable speed drive from the Altivar Solar series, purpose-built to optimize solar-powered pumping systems. It effectively controls the speed and torque of a 3-phase 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 1.5 kW (2 HP) and operates on a three-phase voltage range of 380 to 500 V. It’s designed for a compact installation with an IP20 protection rating and is built with coated circuit boards for enhanced durability in harsh environments. The drive includes integrated Modbus RTU and CANopen communication protocols, allowing for flexible integration into automation systems.
Key Features and Benefits
Maximum Power Point Tracking (MPPT): It uses an integrated MPPT algorithm to constantly find and track the optimal operating point of the solar panels. This maximizes the energy harnessed from the sun, allowing the pump to deliver the highest possible water output throughout the day, even with varying sunlight.
Dual Power Capability: The drive can operate on both solar power and a conventional AC grid connection. This dual-supply feature provides continuous operation, ensuring water is available on cloudy days or at night by automatically switching to the grid when solar power is insufficient.
Pump Protection: It has built-in features to protect the pump and motor, such as dry run protection (which stops the pump when water levels are too low) and an anti-jam function to prevent blockages, significantly extending the equipment’s service life and reducing maintenance.
Easy Commissioning: A dedicated “Sun” menu simplifies the setup process for solar applications, making it quick and intuitive to configure.
Applications
The ATV320U15N4C412 is primarily used in solar water pumping systems for a variety of applications, including:
Agriculture and irrigation, such as for drip systems and sprinklers.
Water supply for remote areas and livestock watering where grid power isn’t available.
Filling water storage tanks and other off-grid water management systems.
