The Schneider Electric ATS22D47Q is a robust and compact Soft Starter belonging to the industry-leading Altistart 22 series. Designed specifically for asynchronous (induction) motors, this device provides a smooth, controlled acceleration and deceleration, significantly reducing mechanical stress on the motor and connected equipment. It is engineered to replace traditional star-delta starters, offering a space-saving, cost-effective, and feature-rich solution for a wide range of industrial applications.

As part of the Altistart 22 family, the ATS22D47Q is optimized for standard and severe applications such as pumps, fans, and compressors. It features an integrated heat sink, internal bypass, and built-in Modbus communication, making it a "plug-and-play" solution for modern automation systems requiring motor protection and process control.

Key Features & Benefits

Smooth Motor Control & Protection:

• Soft Start/Stop: Eliminates mechanical shocks and water hammer effects in piping systems by controlling the voltage ramp-up and ramp-down.
• Current Limiting: Limits the starting current to 3.5 times the nominal current (In), reducing voltage dips in the power supply network.
• Comprehensive Protection: Includes phase failure protection, motor thermal protection (via PTC probe input), and starter thermal protection. It also provides protection against short circuits and overloads.

Advanced Connectivity & Integration:

• Built-in Modbus: Features an RJ45 port supporting Modbus RTU protocol over RS485 physical interface. This allows seamless integration into SCADA systems, PLCs, and HMI panels for remote monitoring and parameter setting.
• Communication Speed: Supports transmission rates of 4800, 9600, or 19200 bps.

Compact & Efficient Design:

• Space-Saving: significantly smaller than traditional star-delta cabinets, saving valuable control panel space (Dimensions: 265 x 130 x 169 mm).
• Internal Bypass: Once the motor reaches full speed, the internal thyristor bypass engages automatically to minimize power dissipation (48W) and extend component life.
• Integrated Heat Sink: The unit comes with a pre-assembled heat sink, ready for immediate installation without additional cooling components.

User-Friendly Operation:

• Status Indication: Features clear LED indicators for power, running, alarm, and trip status.
• Discrete I/O: Comes with 3 Digital Inputs (for Start, Stop, Reset, etc.) and 2 Relay Outputs (for Running, Alarm, Fault signals), allowing easy integration with external control circuits.
• Easy Programming: Can be configured via the built-in keypad or remotely via PC software (PowerSuite).
