High-Performance 3-Phase 11kW Online Soft Starter, 50/60Hz AC Motor Soft Starter
If you are sourcing reliable 11kW 3-phase online soft starter for squirrel-cage asynchronous motors, this PQZR8-Z series online-running soft starter adopts full-time thyristor control without external bypass contactor, delivering smooth soft-start and soft-stop performance. As a cost-saving motor control solution, this 380V AC soft starter effectively suppresses high in-rush starting current, reduces grid impact and mechanical shock caused by direct-on-line motor startup for industrial integrators and end-users.
Equipped with high-speed forced-air cooling radiator and high-quality thyristor power modules, this online type motor soft starter supports 6 optional starting modes including current-limiting start, voltage ramp start and kick-start function to match varied load requirements. The multi-language LCD display shows real-time three-phase current, operating status and fault history for quick on-site troubleshooting. Standard RS485 Modbus communication enables PLC networking and remote monitoring; the detachable operation panel supports remote cabinet-door mounting for convenient local-remote switching. Adjustable start-up time ranges 2-60 seconds and soft-stop time from 0-60 seconds, making it suitable for frequent start-stop working conditions (max 20 starts per hour)Alibaba.co....
Built-in comprehensive multi-layer protection is a key advantage of this 380V industrial soft starter. It covers over-voltage, under-voltage, over-current, over-heat, phase loss, short-circuit, overload and stall protection to safeguard both soft starter and connected motor, avoiding unplanned production shutdown and expensive equipment damage. IP20 indoor enclosure features optimized ventilation structure for stable long-time continuous operation. Besides the 11kW variant, our online soft-starter product portfolio covers power range from 11kW up to 630kW to satisfy diverse motor-control project demands.
This online soft starter for pumps fans compressors conveyors fits broad industrial application scenarios. It is widely deployed for water supply pumps, HVAC ventilation fans, belt conveyors, air compressors, mixers, crushers and agitators in water-treatment plants, mining sites, cement workshops, chemical factories and municipal engineering projects. It minimizes water-hammer effect for pump pipelines, lowers wear on belts and gear sets, serving as ideal upgrade replacement for traditional star-delta and auto-transformer starters.
