Lovato 51ADX0190B severe-duty three-phase soft starter rated at 190 A for 208–500 V AC asynchronous motors, with an integrated bypass contactor and IEC motor ratings up to 132 kW.
£7,226.27
The Lovato 51ADX0190B is an advanced three-phase soft starter designed for controlled starting and stopping of asynchronous three-phase motors in demanding industrial applications. As part of the Lovato Electric ADX...B soft starter series, it is designed for severe-duty operation with a starting current of up to 5 × Ie and incorporates an integrated bypass contactor.
The 51ADX0190B provides three-phase control with torque or voltage ramp starting and current limitation. Multiple stopping modes include torque ramp, voltage ramp and free-wheel stopping, while its control functions include motor current thermal protection, torque control, kick start, dynamic braking, PTC input and event logging.
With a rated starter current of 190 A and a three-phase 208–500 V AC supply, the 51ADX0190B supports IEC motor ratings of 55 kW at 230 V AC, 90 kW at 400 V AC and 132 kW at 500 V AC. Its integrated bypass contactor, forced cooling system and built-in LCD interface make it suitable for demanding industrial motor-starting applications.
Soft starters progressively control the electrical power supplied to a motor during acceleration, helping to reduce the high starting current and mechanical stress associated with direct-on-line starting. The Lovato 51ADX0190B provides three-phase control with configurable torque or voltage ramp starting, allowing acceleration to be matched to the requirements of the motor and driven equipment.
The integrated bypass contactor carries the motor current after the starting sequence is complete, while forced cooling supports operation in demanding applications. Functions including current limitation, motor thermal protection, torque control, kick start, PTC monitoring and event logging provide comprehensive motor management for industrial machinery and process equipment.
