Softstarter with soft coasting UH 9018

Описание

The softstarter UH 9018 is an electronic device designed to enable 1-phase or 3-phase induction motors to start smoothly. The devices slowly ramps up the current on two phases, therefore allowing the motor torque to build up slowly.This reduces the mechanical stress on the machine and prevents damage to conveyed material. These features allow cost saving constructions of mechanical gear. When the motor is up to full speed the power semiconductors in UH 9018 are bridged to prevent internal power losses and heat build up. In addition UH 9018 allows a softstop function prolonging the stop time of the motor, preventing high counter torques from abruptly stopping the motor. Softstart with softstop. For motors from 1.5 kW to 7.5 kW. 2-phase control. Adjustable ramp time, starting torque and starting voltage. Kickstart-(Boost-)function. DIN-rail mounting. Width: 45 mm. Protection of the drive unit. Integrated bridging contactor (Bypass). Easy operation. Comprehensive diagnostic via LED-flashing codes possible
