Schneider Electric ATV312H075S6

Schneider Electric ATV312H075S6 Variable Speed Drive Overview

The Schneider Electric ATV312H075S6 is a high-performance variable speed drive (VSD) designed for asynchronous motors in industrial and commercial applications. As part of the Altivar 312 series, this drive provides precision motor control, energy efficiency, and robust protection features. It operates on a three-phase 525V-600V supply and is rated at 0.75 kW (1 HP), making it ideal for simple machine applications.

Efficient and Reliable Motor Control

This Altivar 312 VSD supports sensorless flux vector control with PWM motor control signals, ensuring smooth acceleration and deceleration. It features a speed range of 1-50 and a nominal switching frequency of 4 kHz, with adjustable settings between 2-16 kHz for flexible operation. The drive also offers automatic motor slip compensation, optimizing performance across load conditions.

Advanced Communication Capabilities

The ATV312H075S6 has Modbus and CANopen communication ports, allowing seamless integration into automation and industrial control systems. The RJ45 Modbus/CANopen interface ensures compatibility with PLC systems and industrial networks, supporting transmission rates up to 1 Mbps (CANopen) and 19,200 bps (Modbus). Optional communication cards for Profibus DP, DeviceNet, and Modbus TCP enhance connectivity.

Robust Protection and Safety Features

Designed for durability and reliability, this variable speed drive includes multiple protection features, such as:

• Input phase break detection
• Overvoltage and undervoltage safety circuits
• Motor phase break detection
• Overcurrent and short-circuit protection
• Thermal protection for motor and drive

These features ensure continuous operation and prevent damage, reducing downtime and maintenance costs.

Energy Efficiency and Performance Optimization

The ATV312H075S6 is engineered to optimize energy consumption while maintaining high performance. It supports braking torque up to 150% with a braking resistor and 100% continuous braking without a resistor, making it suitable for applications requiring precise stopping and starting. The built-in PI frequency regulator allows for stable speed regulation, even under variable loads.

Compact and Easy to Install

With dimensions of 5.6 in (143 mm) height, 4.2 in (107 mm) width, and 6.0 in (152 mm) depth, and weighing only 3.7 lbs (1.7 kg), the ATV312H075S6 is compact and lightweight, facilitating easy installation in control panels. It is designed to operate vertically, ensuring optimal cooling with its heat sink assembly style.

Free Shipping and 2-Year Warranty

MRO Electric and Supply offers free shipping and a 2-year warranty, ensuring customers receive a high-quality and reliable product with excellent after-sales support.
