1.ALD high torque online soft starter is new-generation intelligent motor starting equipment developed based on power electronics, microprocessor and modern control technology.
2.It effectively limits inrush current during motor startup, widely applied for heavy-load equipment including fans, water pumps, conveyors and compressors.
3.Ideal replacement for traditional starter modes: star-delta, autotransformer voltage reduction and magnetic voltage reduction starters.
4.Integrated online structure with three-phase input & three-phase output design. No external bypass contactor required, effectively cutting procurement and construction costs.
1.Equipped with 6 startup modes, 12 comprehensive protection functions and 2 independent stopping modes.
2.Adopts MCU digital intelligent control core, compatible with all squirrel-cage asynchronous motors, realizing smooth motor start and soft stop.
3.Greatly reduce grid impact and mechanical inertia shock caused by sudden startup, well protect whole transmission system.
4.Complete protection system extends service life of motor and mechanical equipment, reduces auxiliary electrical components and overall system cost.
1.Specially designed for heavy-load occasions with large static friction resistance.
2.Output short-term high voltage pulse at initial stage to overcome static friction torque, then follow current-limiting or voltage ramp curve for gradual acceleration.
3.Operation specification: Adopt normal soft start firstly. Switch to kick mode only when motor fails to rotate. Frequent kick startup is forbidden to prevent excessive current damage.
