Schneider Electric ATSU01N209LT Partida Suave Altistart 01

Description

The ATSU01N209LT is an Altistart 01 soft starter designed for the controlled starting and stopping of three-phase asynchronous motors. Rated for a nominal current of 9A, this unit supports a wide supply voltage range of 200–480 V AC, making it a flexible solution for diverse industrial motor applications ranging from 1.5 kW to 4 kW. By providing a smooth, stepless acceleration and deceleration of the motor, the soft starter reduces mechanical stress on gearboxes and drive belts, mitigates current spikes on the power network, and enhances the operational longevity of the driven equipment.

Features

• Soft Starting/Stopping: Reduces mechanical shock and provides smooth torque transitions.
• Compact Design: Small footprint, ideal for installation in space-constrained control panels.
• Broad Voltage Compatibility: Supports 200V to 480V networks, simplifying inventory and application.
• Operational Efficiency: Limits high inrush current, preventing voltage drops and circuit breaker tripping.
• Ease of Use: Simplified adjustment parameters for quick setup and commissioning.

Applications

• Conveyor systems and small material handling equipment.
• HVAC fan and blower motors.
• Centrifugal and reciprocating pump systems.
• Small compressors and specialized machine tools.

Installation Guidelines

• Mounting: Install vertically in a well-ventilated enclosure, ensuring at least 50mm of clearance around the top and bottom to allow for proper thermal dissipation.
• Wiring: Connect the three-phase motor leads to the output terminals and the line supply to the input terminals. Ensure all power connections are torqued to the manufacturer's specified values.
• Control Circuit: Connect the appropriate control signal wiring. The ATSU01 series uses basic control signals to trigger the ramp-up/ramp-down sequence.
• Setting Adjustments: Adjust the voltage ramp time and start/stop settings via the integrated potentiometers to match the load characteristics of your application.
• Safety: Always install external thermal overload protection for the motor, as the soft starter is designed for starting control and may not provide full motor protection functionality.
