Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Altistart 22 Complete Model Number ATS22D47Q Product Type Soft Starter (Motor Starter) Rated Operational Current (Ie) 47 A Motor Power Range (at 400V AC) Approx. 22 kW to 30 kW (30 HP to 40 HP) - Refer to the precise selection tables for exact matching. Supply Voltage 3-phase, 208 - 690 V AC, 50/60 Hz Control Voltage Typically 24V AC (as indicated by code Q). Other control voltages are available in the series (e.g., 100-120V AC, 200-240V AC). Starting Method Voltage ramping with torque control. Provides adjustable: • Initial Torque • Ramp Time • Stop Mode (Freewheel, Ramped deceleration, Braking) Built-in Bypass Yes. Internal bypass contactors reduce heat dissipation during steady-state operation. Protection Features • Motor Thermal Overload Protection (Class 10) • Phase Imbalance • Undercurrent / Jam • Excessive Starting Time / Number of Starts • Heatsink Overtemperature Standard I/O • 2x Digital Inputs (for control commands like Run, Stop, Reset). • 1x Relay Output (for signalling: Ready, Fault, Running, etc.). • 1x Analog Output (0/4-20 mA) for monitoring motor current or other parameters. Communication Integrated RS-485 serial port with Modbus protocol. Optional communication cards available for other networks (e.g., PROFIBUS DP). Enclosure IP00 (open type) or IP20 (finger-safe), designed for panel mounting inside a suitable enclosure. Keypad / Display Integrated keypad and display for local parameter setting, operation, and diagnostics. Ambient Temperature 0°C to +55°C (with derating above 45°C or 50°C). Storage Temperature -25°C to +70°C Standards & Certifications CE, cULus, RoHS, IEC/EN 60947-4-2, UL 508. Configuration Software SoMove (Free software for configuration and monitoring). Typical Applications Water pumping stations, HVAC fans and pumps, conveyor systems, centrifugal compressors, mixers, and any application requiring reduced starting current and controlled acceleration/deceleration for standard three-phase motors.
