The electronic soft starter STJR allows smooth starting and stopping of three-phase motors. The soft starter's power ranges from 5.5 to 500 kW, operates according to a sophisticated control method with a powerful Philips chipset. It prevents mechanical shocks in machinery and voltage dips in the power supply. The softstarter accelerates gently and adjusts the engine torque according to the load characteristics of the machine. The classic star-delta function can be easily replaced. You can install the removable components in different places. With 6 digital inputs and outputs, as well as 6 different start options, an analogue output and an RS485 interface allows optimal integration into existing systems. All in all, the STJR-Softstarter is ideal for pumps, fans, cranes and lifting equipment, as well as conveyor belts and other engines. The variable control of the motor voltage in the starting phase leads to less wear and tear longer as well as increasing the life span of your fan and pump drives. More soft start applications: conveyor system, heat pump, vacuum pump, fan, saw, milling machine, dryer, elevator, door and gate openers, pump, crane, compressor, agitator, centrifuge, pressure washers, etc.
