Electronic ballast/starter Schneider Electric ATS01N112FT White, input 110–480 V, 50/60 Hz, dimming -10–10%

Schneider Electric Altistart ATS01N112FT is a compact soft starter for single- and three-phase AC motors with input voltage from 110 to 480 V and a continuous current rating of 12 A. It provides controlled start and stop functions to limit inrush current, reduce mechanical stress and improve equipment lifetime. The unit supports common motor power classes (reference values 1.5, 2.2 and 5.5 kW at 230/400 V) and is intended for applications that need simple integration, basic motor protection and smooth torque control during acceleration and deceleration.

Advantages

The Altistart ATS01N112FT reduces electrical and mechanical stress on motors and driven equipment by limiting starting current and providing adjustable soft acceleration and deceleration profiles. Its compact footprint and straightforward wiring make it suitable for retrofit and new installations where space and simplicity matter. Built-in protection functions such as overload and phase-loss detection help prevent damage and enable predictable start/stop behaviour that can reduce downtime and maintenance needs.

Suitable for

• Pumps and pump systems that benefit from reduced water hammer and gentler starts
• Fans and ventilators where smooth acceleration improves airflow control
• Conveyors and belt drives requiring controlled starts to avoid product shift or belt slip
• Compressors and small machinery with moderate starting torque requirements

When it may not be suitable

This soft starter is intended for motors within the specified voltage and power ranges; it may not be appropriate for larger motors or applications that require high starting torque beyond its capability. It does not replace a variable frequency drive when precise speed control, energy-saving variable-speed operation or full regenerative control are required.

Key specifications

• Supply voltage range: 110–480 V, single- and three-phase
• Frequency: 50/60 Hz

• Fast start-up time: approximately 1 s (as noted in product data)
• Control functions: soft start and soft stop to limit inrush current and mechanical shock
• Protection features: overload and phase-loss detection (basic motor protection)
• Finish and mounting: white finish, compact design suitable for panel mounting

How to use

Install the Altistart ATS01N112FT in a suitably sized enclosure or control panel following Schneider Electric installation instructions and local electrical codes. Connect supply and motor conductors to the designated terminals, configure start/stop control inputs and adjust start/stop ramp times to meet the mechanical requirements of the driven load. Verify correct phase sequence, set protection thresholds and test the soft start/stop behaviour under light load before placing the equipment into regular operation. If the application uses the dimming/control range, configure the control interface according to the wiring and parameter settings provided by the manufacturer.

What to consider before purchase

• Confirm motor rated voltage and power to ensure compatibility with the device's supported ranges
• Check required starting torque and whether a soft starter provides sufficient torque compared with a VFD
• Assess available panel space, mounting orientation and thermal conditions for correct installation and ventilation
• Review control integration needs (start/stop inputs, fault signaling and any dimming/control range) to match the installation design

Usage recommendations

Set start and stop ramp times to the minimum required to reduce mechanical stress while ensuring reliable acceleration. Perform periodic checks of electrical connections and monitor protection alarms to detect phase imbalance or overload conditions early. For applications needing precise speed control, frequent reversing or significant energy savings through variable-speed operation, consider a variable frequency drive instead of a soft starter.
